FDA approves sealant to prevent cerebrospinal fluid leaks after brain surgery.
The DuraSeal Dural Sealant System is used in dura mater surgery and is applied over sutures to prevent CSF fluid from leaking out of the incision site. The dura mater is the tough, outermost fibrous membrane that covers the brain and spinal cord, and lines the inner surface of the skull. Leakage of CSF can lead to serious complications, such as severe headaches, infection and meningitis.
