Cerebrospinal fluid (CSF) leak is a common complication of spinal and cranial surgery, and patients undergoing spinal tumor surgery are probably particularly predisposed due to the presence of an intradural tumor and many other factors. Furthermore, a meticulous dural closure technique does not always result in watertight closure. A number of adjunctive methods have been used to assist with dural closure. Synthetic, absorbable polyethylene glycol hydrogel dural sealants are widely used and have been approved for use as adjuncts for cranial applications requiring sutured dural closure. We report a case of thecal sac compression by DuraSeal® Dural Sealant used to repair the CSF leak after intentional durotomy during lumbar schwannoma extirpation.
