Abstract:we included 58 patients, mean age 46 years , 65% female, with the diagnosis of SIH. We treated 38 ventral leaks, 17 dorsal/lateral leaks, 2 CSF-venous fistulas.

Leaks were visualized via a transdural approach, after cutting the dentate ligament and lateralization of the ventral dura. Microspurs were removed and leaks were closed by sandwich patch using a fibrin sealant patch (ventral leaks) or clippin… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
