Cervical spine csf leak mri11/10/2023 ![]() In this article, the incidence, risk factors and complications of CSF leaks after spine tumor surgery are reviewed, with an emphasis on avoidance of post-operative CSF leaks, early post-operative identification and effective secondary intervention.Ĭerebrospinal fluid (CSF) leaks are a known complication of spine surgery, and an effective protocol for prevention, recognition and treatment of postoperative CSF leakage is essential to avoiding a cascade of associated adverse outcomes, such as durocutaneous fistula, wound infection ( 1- 5), intracranial hemorrhage ( 6- 12), arachnoiditis ( 13, 14), nerve root incarceration/strangulation ( 15, 16) and meningitis ( 3- 5, 17). Intraoperative identification of unintended durotomies and effective primary repair of dural defects is an important first step in the prevention of post-operative CSF leaks, but in patients who develop post-operative pseudomeningoceles, durocutaneous fistulae or other CSF-leak-related sequelae, early recognition and secondary intervention are paramount to preventing further CSF-leak-related complications and achieving the best patient outcomes possible. Post-operative CSF leaks increase morbidity, lengthen hospital stays, prolong immobilization and subject patients to a number of associated complications. Post-operative CSF leaks are a known complication of spine surgery in general, and patients undergoing surgical intervention for spinal tumors may be particularly predisposed due to the presence of intradural tumor and a number of other factors. ![]()
