Summary

Epidural blood patching (EBP) is an important therapeutic approach in managing spontaneous cerebrospinal fluid leaks. The mechanism of action of blood patching is likely to be twofold; fluid replacement having an immediate tamponade effect and the proximal flow of blood products having a ‘plug’ effect. The negative pressure gradient within the epidural space may be important to the rostral flow of injected blood and is possibly increased in intracranial hypotension.
