Management of CSF leaks after spinal surgery

Subspecialty: Spine

Type: Clinical Summary

Educational content sponsored by Joint Operations, the official distributor of LiquoGuard 7: Postoperative cerebrospinal fluid (CSF) leak after spinal surgery results from dural defects that create a path for CSF egress, increasing risk of wound breakdown, pseudomeningocele, pleural effusion and meningitis; management aims to reduce the pressure gradient across the dural defect and support watertight closure. This review and associated studies examine patient-specific automated CSF pressure/volume control using the LiquoGuard7 system, the physiologic basis of CSF production rate (prCSF), the e…
