Vicryl (polyglactin 910) mesh as a dural substitute

Abstract

Many substances have been used as dural substitutes. Although the various materials are effective in a variety of settings, a material that is absorbed over time, elicits minimal inflammatory reaction, is relatively inexpensive, and is easily manipulated would be beneficial. An experimental project was conducted involving closure of dural defects in dogs with a Vicryl (polyglactin 910) mesh graft. Macroscopic and histological examination performed at various times after placement revealed resorption of the graft material, little cerebromembranous adhesion formation, and complete lack of injury to subjacent cortical zones. A substantial neomembrane forms over the zone of the mesh graft. The authors suggest that Vicryl mesh has significant potential as an absorbable, minimally reactive dural substitute.
