OBJECTIVE:Previous studies have retrospectively analyzed the likely causes of cerebrospinal fluid leakage (CSFL) during cervical spine surgery and the management of CSFL after its occurrence. In the present study, we aimed to develop and validate a nomogram for the risk of CSFL in Chinese patients who had undergone cervical decompression and internal fixation (CDIF) surgery. METHODS:We performed a retrospective analysis of patients who had undergone CDIF surgery. Of the 1286 included patients, 54 were in the CSFL group and 1232 were in the normal group. The patients were randomly divided into training and validation tests. The risk assessment for CSFL included 21 characteristics. The feature selection for the CSFL model was optimized using the least absolute shrinkage and selection operator regression model in the training test. Multivariate logistic regression analysis was performed to construct the model according to the selected characteristics. The clinical usefulness of the predictive model was assessed using the C-index, calibration curve, and decision curve analysis with identification and calibration. RESULTS:The risk prediction nomogram included the diagnosis, revision surgery, ossification of the posterior longitudinal ligament, cervical instability, and a history of malignancy in the training test. The model demonstrated high predictive power, with a C-index of 0.914 (95% confidence interval, 0.876-0.951) and an area under the curve of 0.914. The results of the decision curve analysis demonstrated the clinical usefulness of the CSFL risk nomogram when the probability threshold for CSFL was 1%-62%. CONCLUSIONS:Our proposed nomogram for CSFL risk includes the diagnosis, revision surgery, ossification of the posterior longitudinal ligament, cervical instability, and a history of malignancy. The nomogram can be used to evaluate the risk of CSFL for patients undergoing CDIF surgery.

Kinaci Ahmet,Moayeri Nizar,van der Zwan Albert,van Doormaal Tristan P C
World neurosurgery
BACKGROUND:Sealants are often used in spine surgery to prevent postoperative cerebrospinal fluid (CSF) leakage. OBJECTIVE:To investigate the efficacy of sealants in preventing postoperative CSF leakage in spine surgery. METHODS:The PubMed, Embase, and Cochrane databases were searched for articles reporting the outcome of patients treated with a sealant for spinal dural repair. The number of patients, indication of surgery, surgical site, applied technique, type of sealant used, and outcome in terms of postoperative CSF leakage were noted for each study. The primary outcome was CSF leakage in general and secondary outcome infection. RESULTS:Forty-one articles were selected with a total of 2542 cases; there were 4 comparative studies with 540 sealed cases and 343 cases with primary suture closure only. The quantity of CSF leakage did not differ between the sealant group (50 of 540, 9.1%) and the group treated with sutures only (48 of 343, 13.8%) (risk ratio [RR], 0.58 [confidence interval [CI], 0.18-1.82]). The infection rate did also not differ between the sealant and primary suture groups (RR, 0.94 [CI, 0.55-1.61]). This result was found in both the intended and the unintended durotomy subgroups. Secondary analysis of all cases showed that endoscopic or minimally invasive surgery had lower CSF leakage rates compared with open surgery regardless of sealant use (RR, 0.18 [CI, 0.05-0.75]). CONCLUSIONS:Currently available sealants seem not to reduce the rate of CSF leakage in spine surgery. In endoscopic and minimally invasive surgery, the CSF leakage rate is less frequent compared with open, conventional surgery regardless of sealant use.

Electrophoresis
A simple and rapid detection of cerebrospinal fluid (CSF) leakage would benefit spine surgeons making critical postoperative decisions on patient care. We have assessed novel approaches to selectively determine CSF β2-transferrin (β2TF), an asialo-transferrin (aTF) biomarker, without interference from serum sialo-transferrin (sTF) in test samples. First, we performed mild periodate oxidation to selectively generate aldehyde groups in sTF for capture with magnetic hydrazide microparticles, and selective removal with a magnetic separator. Using this protocol sTF was selectively removed from mixtures of CSF and serum containing CSF aTF (β2TF) and serum sTF, respectively. Second, a two-step enzymatic method was developed with neuraminidase and galactose oxidase for generating aldehyde groups in sTF present in CSF and serum mixtures for magnetic hydrazide microparticle capture. After selectively removing sTF from mixtures of CSF and serum, ELISA could detect significant TF signal only in CSF, while the TF signal in serum was negligible. The new approach for selective removal of only sTF in test samples will be promising for the required intervention by a spine surgeon.

Biochemia medica
INTRODUCTION:The management of posttraumatic cerebrospinal fluid (CSF) rhinorrhoea remains a clinical challenge. Cerebrospinal fistula is a dural defect responsible for possible CSF leakage into the contiguous air-filled cavities located at the skull base. The risk of central nervous system infection in these conditions is severe and can be life threatening. Consequently, a specific CSF biomarker might be used in case of difficult diagnosis of CSF rhinorrhoea. CSF Tau protein is a neuronal protein, commonly assessed for diagnosis of Alzheimer Disease (AD). The aim of this study was to determine whether the Tau protein could be a relevant marker of CSF leakage. MATERIALS AND METHODS:Tau protein measurement was performed by enzyme-linked immunosorbent assay in 13 patients with CSF leakage (CSF rhinorrhoea group), and 8 patients with spontaneous aqueous rhinorrhoea (non-CSF leakage group). The serum concentration of Tau protein was measured by ELISA in both CSF rhinorrhoea group and non-CSF leakage group. RESULTS:In patients with CSF leakage, CSF Tau protein median concentration was 479 ng/L (197 - 2325 ng/L). On the other hand, the Tau protein concentration was below the lower limit of quantification (LLoQ) (< 87 ng/L) in non-CSF leakage group. Serum Tau protein concentration by ELISA was also below LLoQ (< 87 ng/L) for all subjects. CONCLUSION:ELISA measurement of Tau protein in rhinorrhoea fluid may be a reliable and relevant marker for detecting the presence of CSF in the nasal discharge and sign the existence of a CSF leakage.

Zhongguo gu shang = China journal of orthopaedics and traumatology
OBJECTIVE:To explore the effectiveness of absorbable hemostatic fluid gelatin in preventing postoperative cerebrospinal fluid leakage. METHODS:The clinical data of 17 patients with dura mater tear were retrospectively analyzed from March to September in 2003. There were 16 males and 1 female, aged from 16 to 67 years old with an average of (39.6 ± 15.4) years. The injury site was at cervical vertebrae in 1 case, thoracic vertebrae in 9 cases, thoracolumbar junction in 4 cases, lumbar vertebrae in 3 cases. There were burst fracture in 4 cases and fracture-dislocation in 13 cases. According to ASIA grade, 12 cases were grade A, 2 cases were grade B, 2 cases were grade D, 1 case were grade E. Two cases caused by traffic accident, 10 by high falling, 4 by heavy parts crash, 1 by stairs fell during the earthquake. Absorbable hemostatic fluid gelatins were used to plug the dura mater tear,in order to prevent postoperative cerebrospinal fluid leakage. Postoperative drainage were recorded every day. RESULTS:Of 17 patients, 15 cases did not develop with cerebrospinal fluid leakage. Two cases develop with cerebrospinal fluid leakage after operation and their drainage were removed at 6 to 7 days after operation. In all cases, no complications related with cerebrospinal fluid leakage occurred, such as headache, dizzy, fever,neck resistance, rash, incision disunion, incision infection, hematoma, neurologic symptoms aggravation. No abnormal phenomena was found on incision surrounding at follow-up of 9 months. CONCLUSION:Using absorbable hemostatic fluid gelatin to plug the dura mater tear during operation is an effective method in preventing postoperative cerebrospinal fluid leakage.

Chinese journal of traumatology = Zhonghua chuang shang za zhi
Owing to the complexity of spinal surgery, there is a great prevalence of dural tear causing cerebrospinal fluid (CSF) leakage. Many studies focused on suture repair for dural tear to stop CSF leak. Now some new treatment strategies have shown a promising effect that is listed as follows: 1) creating watertight dural closure to stop CSF leak with the help of dural substitute material; and 2) retarding CSF leak by changing pressure difference, including reducing the subarachnoid fluid pressure, increasing the epidural space pressure and both. In fact several methods mentioned above are usually combined to treat CSF leak. However, no update review summarized the relevant studies implemented in recent years. In this review, the authors would compare the effects of different dural closure techniques, and introduce the latest treatment methods and mechanisms.

Risk Factors for Cerebrospinal Fluid Leakage After Extradural Spine Surgery: A Meta-Analysis and Systematic Review.
World neurosurgery
BACKGROUND:Cerebrospinal fluid (CSF) leakage is 1 of the common complications of spine surgery and is largely caused by intraoperative or postoperative dural tears. Associations of different factors with postoperative CSF leakage have not been consistent. In this study we aimed to identify demographic, disease-related, and surgical risk factors for CSF leakage after extradural spine surgery in a systematic review and meta-anlysis. METHODS:The PubMed, EMBASE, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Chinese Wanfang data, Chinese Weipu Database, and SinoMed databases were searched from inception until October 24, 2022. Fixed-effects or random-effects models were used to calculate odds ratios and 95% confidence intervals. The quality of observational studies was evaluated using the Newcastle-Ottawa scale instrument. RESULTS:A total of 15 observational studies with 1,719,923 participants were included in this systematic review. All studies had a Newcastle-Ottawa scale score greater than or equal to 6. Age older than 70 years, smoking, ossification of the posterior longitudinal ligament, adhesion of spinal dura, spinal canal stenosis, cervical fracture, spondylolisthesis, revision surgery, and multiple surgical segments were all related to CSF leakage in the pooled analysis. Obesity and disease duration>1 year were not associated with the leakage of CSF. CONCLUSIONS:This study will provide a reference for the identification of patients at high risk of developing CSF leakage, which suggests clinicians to strengthen the observation of drainage fluid in high-risk groups.

Analytica chimica acta
Cerebrospinal fluid (CSF) leakage due to incidental durotomy is an inherent complication of spine surgery. With appropriate treatment, complications of CSF leakage, such as headache and even meningitis, can be reduced. CSF leakage could be detected on the basis of correlated clinical symptoms; diagnosis should be based on these symptoms and appropriate imaging studies. However, the diagnosis of CSF leakage remains a challenge, especially if incidental durotomy is unrecognized during surgery; even if incidental durotomy is detected and repaired intraoperatively, the severity of the leakage and quality of the primary dural repair are difficult to evaluate postoperatively. Rapid, inexpensive, and safe methods of detecting CSF-containing samples are currently lacking; hence, the development of a point-of-care test (POCT) method to improve diagnostic efficiency is necessary. We developed a high-sensitivity lateral flow immunoassay with a stacking pad (sLFIA) for quantitative detection of β-trace protein (BTP), a specific CSF marker. The BTP concentration in 39 clinical samples was calculated using a calibration equation for test-line intensity and evaluated by a standard laboratory method. To avoid the hook effect, we diluted each sample prior to testing. The correlation coefficient between the enzyme-linked immunosorbent assay and our BTP sLFIA method was 0.991 A 75-fold sample dilution was applied owing to the hook effect point, identified as 175 ng mL. We established an optimal sample-specific cutoff point at a value of 4.0 μg mL for CSF leakage in subfascial drainage samples following spinal posterior decompression. The sensitivity and specificity of the BTP sLFIA method were 90% and 97%, respectively, according to a receiver operating characteristic curve analysis. In addition, clinical samples from patients who underwent primary dural repair intraoperatively were tested, and CSF leakage was successfully diagnosed using our method. Finally, the quantitation of BTP in samples collected daily provided an accurate assessment of the severity of the residual leakage. Our results demonstrate that the BTP sLFIA method possesses the potential to serve as a POCT method for screening and monitoring postoperative CSF leakage.

Risk factors and management strategies for cerebrospinal fluid leakage following lumbar posterior surgery.
BMC surgery
OBJECTIVE:To analyze the risk factors of cerebrospinal fluid leakage (CSFL) following lumbar posterior surgery and summarize the related management strategies. METHODS:A retrospective analysis was performed on 3179 patients with CSFL strategies lumbar posterior surgery in our hospital from January 2019 to December 2020. There were 807 cases of lumbar disc hemiation (LDH), 1143 cases of lumbar spinal stenosi (LSS), 1122 cases of lumbar spondylolisthesis(LS), 93 cases of lumbar degenerative scoliosis(LDS),14 cases of lumbar spinal benign tumor (LST). Data of gender, age, body mass index(BMI), duration of disease, diabete, smoking history, preoperative epidural steroid injection, number of surgical levels, surgical methods (total laminar decompression, fenestration decompression), revision surgery, drainage tube removal time, suture removal time, and complications were recorded. RESULTS:The incidence of 115 cases with cerebrospinal fluid leakage, was 3.6% (115/3179).One-way ANOVA showed that gender, body mass index (BMI), smoking history, combined with type 2 diabetes and surgical method had no significant effect on CSFL (P > 0.05). Age, type of disease, duration of disease, preoperative epidural steroid injection, number of surgical levels and revision surgery had effects on CSFL (P < 0.05). Multivariate Logistic regression analysis showed that type of disease, preoperative epidural steroid injection, number of surgical levels and revision surgery were significantly affected CSFL (P < 0.05).Drainage tube removal time of CSFL patients ranged from 7 to 11 days, with an average of 7.1 ± 0.5 days, drainage tube removal time of patients without CSFL was 1-3 days, with an average of 2.0 ± 0.1 days, and there was a statistical difference between the two groups (P < 0.05).The removal time of CSFL patients was 12-14 days, with an average of 13.1 ± 2.7 days, and the removal time of patients without CSFL was 10-14 days, with an average of 12.9 ± 2.2 days, there was no statistically significant difference between the two groups (P > 0.05). CONCLUSION:Type of disease, preoperative epidural steroid injection, number of surgical levels and revision surgery were the risk factors for CSFL. Effective prevention were the key to CSFL in lumbar surgery. Once appear, CSFL can also be effectively dealt without obvious adverse reactions after intraoperative effectively repair dural, head down, adequate drainage after operation, the high position, rehydration treatment, and other treatments.

Chen Hung-Chieh,Chen Po-Lin,Chai Jyh-Wen,Teng Chieh-Lin Jerry
BMC neurology
BACKGROUND:Spinal cerebrospinal fluid (CSF) leakage is frequently encountered clinically after lumbar puncture or spontaneous events. Although some patients recover without treatment or after intensive hydration, some require an epidural blood patch (EBP). The risks of nonresponsive hydration remain unknown. Therefore, we identified the risk factors for patients with spinal CSF leakage nonresponsive to hydration. METHODS:We retrospectively reviewed patients diagnosed with spinal CSF leakage between January 2010 and March 2021. Clinical data, including patient age, sex, etiology, and radiological indications in magnetic resonance imaging, were compared between patients who were responsive and non-responsive to hydration. RESULTS:Of the 74 patients with spinal CSF leakage, 25 were responsive to hydration and 49 required EBP. Patients who were nonresponsive to hydration were older (39.27 vs. 34.32 years, P = 0.01), had a higher percentage of spontaneous intracranial hypotension (93.88% vs. 68.00%, P = 0.005), had more spinal CSF leakage (12.04 vs. 8.04, P = 0.01), and had a higher percentage of dural sinus engorgement (81.63% vs. 60.00%, P = 0.044). Spontaneous intracranial hypotension (odds ratio [OR]: 4.63; 95% confidence interval [CI]: 1.00-21.38) and having ≥9 spinal CSF leakages (OR: 3.29; 95% CI: 1.08-10.01), as indicated by magnetic resonance myelography, are considered risk factors for noneffective hydration. CONCLUSIONS:Patients with spinal CSF leakage who have spontaneous intracranial hypotension and those with ≥9 spinal CSF leakages are considered at risk for noneffective hydration. EBP should be considered early in these patients.

Cerebrospinal fluid (CSF) leakage is a serious postoperative complication associated with total en bloc spondylectomy. The authors examined the risk factors for CSF leakage after this procedure. A total of 72 patients underwent total en bloc spondylectomy at the authors' institution between May 2010 and April 2013. Postoperative CSF leakage was observed in 17 of the 72 patients (23.6%). The results of univariate analysis suggested that age 54 years or older, preoperative surgical site irradiation, resection of 3 or more vertebral bodies, and dural injury were significant risk factors for postoperative CSF leakage after total en bloc spondylectomy. Multivariate analysis showed that preoperative surgical site irradiation was the only significant risk factor for postoperative CSF leakage (adjusted odds ratio, 5.22; 95% confidence interval, 1.03-26.45, P=.046). The authors also assessed the course of treatment for postoperative CSF leakage in each patient. Of 17 patients with postoperative CSF leakage, 13 recovered without further complications, but 4 required reoperation (2 for wound dehiscence, 1 for surgical site infection, and 1 for severe intracranial hypotension). All 4 patients who required reoperation had a history of surgical site irradiation. Thus, this study suggests that careful consideration should be given to postoperative CSF leakage in patients with a history of surgical site irradiation. These findings may contribute to the management of postoperative CSF leakage associated with total en bloc spondylectomy and supplement the information given to the patient in the process of obtaining informed consent.

Determination of cerebrospinal fluid leakage by selective deletion of transferrin glycoform using an immunochromatographic assay.
Oh Jusung,Kwon Seok-Joon,Dordick Jonathan S,Sonstein William J,Linhardt Robert J,Kim Min-Gon
Theranostics
Cerebrospinal fluid (CSF) leakage can lead to brain and spine pathologies and there is an urgent need for a rapid diagnostic method for determining CSF leakage. Beta-2 transferrin (β2TF), asialotransferrin, is a specific CSF glycoprotein biomarker used to determine CSF leakage when distinguished from serum sialotransferrin (sTF). : We detected β2TF using an immunochromatographic assay (ICA), which can be potentially developed as a point-of-care (POC) testing platform. Sialic acid-specific lectin selectively captures sTF in multiple deletion lines within an ICA test strip, enabling the detection of β2TF. A sample pre-treatment process efficiently captures excess sTF increasing sensitivity for CSF leakage detection. : An optimal cut-off value for determining the presence of CSF in test samples was obtained from receiver operating characteristic (ROC) analysis of the ratio of the test signal intensity and the deletion lines. On 47 clinical samples, ICA test strips discriminated CSF positive from negative samples with statistically significant (positive negative t-test; =0.00027). Additional artificial positive samples, prepared by mixing CSF positive and negative clinical samples, were used as a further challenge. These positive samples were clearly discriminated from the negative samples (mixture negative t-test; =0.00103) and CSF leakage was determined with 97.1% specificity and 96.2% sensitivity. : ICA represents a promising approach for POC diagnosis of CSF leakage. While requiring 70 min assay time inconvenient for POC testing, our method was significantly shorter than conventional electrophoresis-based detection methods for β2TF.

Community-acquired Bacterial Meningitis in Adults With Cerebrospinal Fluid Leakage.
Ter Horst Liora,Brouwer Matthijs C,van der Ende Arie,van de Beek Diederik
Clinical infectious diseases : an official publication of the Infectious Diseases Society of America
BACKGROUND:Cerebrospinal fluid (CSF) leakage is a risk factor for developing bacterial meningitis. METHODS:We analyzed episodes of community-acquired bacterial meningitis associated with CSF leakage from a prospective nationwide cohort study. RESULTS:CSF leakage was identified in 65 episodes of 2022 episodes (3%) in 53 patients. The cause of CSF leakage was identified in 49 of 65 episodes (75%), which most commonly consisted of ear-nose-throat surgery (19 of 49 episodes [29%]) and remote head trauma (15 of 49 episodes [23%]). The episode was a recurrent meningitis episode in 38 patients (59%). Of the recurrent episodes, 27 had known CSF leakage (71%) of whom 20 (53%) had previous surgery aiming to close the leak. Nine patients (38%) with known CSF leakage had been vaccinated (23-valent pneumococcal vaccine in 9 patients, meningococcal serogroup C vaccine in 2, meningococcal serogroup A and Haemophilus influenzae type b vaccine each in 1 patient). Streptococcus pneumoniae was cultured in 33 episodes (51%) and H. influenzae in 11 episodes (17%). The most common pneumococcal serotypes were 3 (4 episodes), 35B, 9N, 38, and 15C (each 2 episodes). Haemophilus influenzae was unencapsulated in all 10 episodes with known capsule type. The outcome was unfavorable in 8 episodes (12%) and no patient died. CONCLUSIONS:Bacterial meningitis in patients with CSF leakage has a high recurrence rate, despite surgical repair or vaccination, and outcome is generally favorable. CSF leakage should be suspected in patients with bacterial meningitis presenting with liquorrhea, recurrent meningitis, or with disease caused by H. influenzae.

Risk Factors for Postoperative Cerebrospinal Fluid Leakage After Intradural Spine Surgery.
World neurosurgery
OBJECTIVE:Well-defined risk factors for cerebrospinal fluid leakage (CSFL) after intradural spine surgery are scarce in the literature. The aim of the present study was to identify patient- and surgery-related risk factors and the incidence of CSFL. METHODS:For the present retrospective cohort study, we identified consecutive patients who had undergone intradural spine surgery between 2009 and 2021 at our department. The primary endpoint was the incidence of clinically or radiologically proven CSFL. The effects of the clinical and surgical factors on the occurrence of CSFL were analyzed. RESULTS:A total of 375 patients (60.3% women; mean age, 54 ± 16.5 years) were included. Of the 375 patients, 30 (8%) had experienced postoperative CSFL and, thus, a significantly greater risk of wound healing disorders (odds ratio [OR], 24.9; 95% confidence interval [CI], 9.3-66.7) and surgical site infections (OR, 8.4; 95% CI, 2.6-27.7; P < 0.01 for each). No patient-related factors were associated with the development of CSFL. Previous surgery at the index level correlated significantly with the occurrence of postoperative CSFL (OR, 2.76; 95% CI, 1.1-6.8; P = 0.03) on multivariate analysis. Furthermore, patients with intradural tumors tended to have a greater risk of CSFL (OR, 2.3; 95% CI, 0.9-5.8; P = 0.07). Surgery-related factors did not influence the occurrence of CSFL. Surgery on the thoracic spine had resulted in a significantly lower postoperative CSFL rate compared with surgery on the cervical or lumbar spine (OR, -2.5; 95% CI, 1.3-4.9; P = 0.02). CONCLUSIONS:Our study found no modifiable risk factors for preventing CSFL after intradural spine surgery. Patients with previous surgery at the index level had a greater risk of CSFL. The occurrence of CSFL resulted in significantly more wound healing disorders and surgical site infections, necessitating further therapy.

Dural sealants for the management of cerebrospinal fluid leakage after intradural surgery: current status and future perspectives.
Kinaci Ahmet,Van Doormaal Tristan P C
Expert review of medical devices
: Cerebrospinal fluid leakage is a complication after intradural surgery and is associated with severe secondary complications like compromised wound healing and meningitis. Dural sealants are meant to augment the primary dural closure in order to achieve a watertight closure. : This review summarizes the efficacy of currently available dural sealants. Potential future improvements and biomaterials are discussed. : The use of a dural sealant seems to be the logical method to prevent CSF leakage. However, based on the efficacy of currently available dural sealants according to systematic reviews and studies, a significant effective dural sealant seems is still lacking. A new dural sealant has to be thoroughly assessed before clinical application in , in vivo and clinical trials. A new research area within sealant development might be the introduction of dural sealants with both antimicrobial and analgesic properties.

Cerebrospinal fluid leakage prevention using the anterior transpetrosal approach with versus without postoperative spinal drainage: an institutional cohort study.
Neurosurgical review
The efficacy of spinal drain (SD) placement for cerebrospinal fluid (CSF) leakage prevention after the anterior transpetrosal approach (ATPA) remains unclear. Thus, we aimed to assess whether postoperative SD placement improved postoperative CSF leakage after a skull base reconstruction procedure using a small abdominal fat and pericranial flap and clarify whether bed rest with postoperative SD placement increased the length of hospital stay. This retrospective cohort study included 48 patients who underwent primary surgery using ATPA between August 2011 and February 2022. All cases underwent SD placement preoperatively. First, we evaluated the necessity of SD placement for CSF leakage prevention by comparing the postoperative routine continuous SD placement period to a period in which the SD was removed immediately after surgery. Second, the effects of different SD placement durations were evaluated to understand the adverse effects of SD placement requiring bed rest. No patient with or without postoperative continuous SD placement developed CSF leakage. The median postoperative time to first ambulation was 3 days shorter (P < 0.05), and the length of hospital stay was 7 days shorter (P < 0.05) for patients who underwent SD removal immediately after surgery (2 and 12 days, respectively) than for those who underwent SD removal on postoperative day 1 (5 and 19 days, respectively). This skull base reconstruction technique was effective in preventing CSF leakage in patients undergoing ATPA, and postoperative SD placement was not necessary. Removing the SD immediately after surgery can lead to earlier postoperative ambulation and shorter hospital stay by reducing medical complications and improving functional capacity.

Cerebrospinal fluid leakage after intradural spinal surgery in children.
Child's nervous system : ChNS : official journal of the International Society for Pediatric Neurosurgery
PURPOSE:This study aimed to establish the incidence of CSF leakage in children and associated complications after intradural spinal surgery in three tertiary neurosurgical referral centers and to describe the treatment strategies applied. METHODS:Patients of 18 years or younger who underwent intradural spinal surgery between 2015 and 2021 in three tertiary neurosurgical referral centers were included. Patients who died or were lost to follow-up within six weeks after surgery were excluded. The primary outcome measure was CSF leakage within six weeks after surgery, defined as leakage of CSF through the skin. Secondary outcome measures included the presence of pseudomeningocele (PMC), meningitis, and surgical site infection (SSI). RESULTS:We included a total of 75 procedures, representing 66 individual patients. The median age in this cohort was 5 (IQR = 0-13 years. CSF leakage occurred in 2.7% (2/75) of procedures. It occurred on days 3 and 21 after the index procedure, respectively. One patient was treated with a pressure bandage and an external lumbar drain on day 4 after diagnosis of the leak, and the other was treated with wound revision surgery on day 1 after the leak occurred. In total, 1 patient developed a PMC without a CSF leak which was treated with wound revision surgery. SSI occurred in 10.7%, which included both cases of CSF leak. CONCLUSIONS:CSF leakage after intradural spinal surgery in the pediatric population is relatively rare (2.7%). Nevertheless, the clinical consequences with respect to secondary complications such as infection and the necessity for invasive treatment are serious.

Prompt diagnosis and early treatment of cerebrospinal fluid (CSF) leakage minimizes the risk of severe complications. In patients presenting with clear fluid nasal discharge it is important to identify the nature of the rhinorrhea. The CSF leakage may occur as post-traumatic, iatrogenic, spontaneous or idiopathic rhinorrhea. The differential diagnosis of CSF rhinorrhea often presents a challenging problem. The confirmation of CSF rhinorrhea and localization of the leakage may be diagnosed by CT, MRI cisternography and MRI cisternography in combination with single photon emission tomography or radioisotopic imaging. Although these methods allow estimation of the CSF leakage with high accuracy, they are expensive and invasive procedures. Therefore, biochemical methods are still used in the differentiation. Although the most common diagnostic method for screening CSF leakage is glucose oxidase, its diagnostic sensitivity and specificity is generally unsatisfactory. False negative results may occur with bacterial contamination and false positive results are common in diabetic patients. Glucose detection is not recommended as a confirmatory test. As such, other biomarkers of the CSF leakage, such as beta-2-transferrin (beta-2 trf) and beta-trace protein (betaTP) are necessary to identify and confirm of this condition.

Hu Pan-Pan,Liu Xiao-Guang,Yu Miao
Chinese medical journal
OBJECTIVE:The objective of this study is to review cerebrospinal fluid leakage (CSFL) after thoracic decompression and describe its regular and special features. DATA SOURCES:Literature cited in this review was retrieved from PubMed and Medline and was primarily published during the last 10 years. "Cerebrospinal fluid", "leakage", "dural tears", and "thoracic decompression" were the indexed terms. Relevant citations in the retrieved articles were also screened to include more data. STUDY SELECTION:All retrieved literature was scrutinized, and four categories were recorded: incidence and risk factors, complications, treatment modalities, and prognosis. RESULTS:CSFL is much more frequent after thoracic decompression than after cervical and lumbar spinal surgeries. Its occurrence is related to many clinical factors, especially the presence of ossified ligaments and the adhesion of the dural sac. While its impact on the late neurological recovery is currently controversial, CSFL increases the risk of other perioperative complications, such as low intracranial pressure symptoms, infection, and vascular events. The combined use of primary repairs during the operation and conservative treatment postoperatively is generally effective for most CSFL cases, whereas lumbar drains and reoperations should be implemented as rescue options for refractory cases only. CONCLUSIONS:CSFL after thoracic decompression has not been specifically investigated, so the present study provides a systematic and comprehensive review of the issue. CSFL is a multi-factor-related complication, and pathological factors play a decisive role. The importance of CSFL is in its impact on the increased risk of other complications during the postoperative period. Methods to prevent these complications are in need. In addition, though the required treatment resources are not special for CSFL after thoracic decompression, most CSFL cases are conservatively curable, and surgeons should be aware of it.
