Abstract
Background: Cerebrospinal fluid (CSF) leak is a serious complication of endoscopic endonasal surgery for pituitary adenoma; leading to a more serious and financial burden of the surgery. Prediction of the occurrence of such sequale and proper plaining for reconstruction can reduce its prevalence and associated morbidities. Purpose: To determine the predictors and risk factors associated with intra/and postoperative cerebrospinal fluid (CSF) leaks in endoscopic endonasal pituitary surgery. Methods: A retrospective study included 150 patients who underwent endoscopic endonasal approach for resection of pituitary adenomas between 2015 and 2018. We analyzed the association between CSF leaks (intra/post-operative) and perioperative variables including patients’ demographic data, medical comorbidities, tumor characteristics and operative data (rates of intraoperative leak, reconstructive techniques). Results: 34 patients (22.6%) out of the 150 patients had an overall, CSF leak: 26 (76.5%) patients had intraoperative leaks; 5 patients out of them continued to have a postoperative leak. 8 patients (23.5%) had postoperative leak. Based on multiple logistic regression model analysis; increased body mass index (BMI), associated hydrocephalus, suprasellar extension and recurrent tumors had a significant association with intraoperative CSF leaks, while only BMI and hydrocephalus predicted postoperative CSF leaks. Conclusion: Elevated BMI, suprasellar extension of the tumor, recurrence or previous radiation are all important risk factors that have been proved in this study to have statistically significant association with the incidence of CSF leak. In high risk patients for CSF leakage: adequate reconstruction planis advised to avoid such morbidity.
