Abstract:Aneurysms involving the origin of the posterior inferior cerebellar artery (PICA) have a greater incidence of fusiform morphology, intraluminal thrombi, and wall calcifications. At times, a complex treatment strategy with vessel occlusion and revascularization using a bypass graft is necessary for successful obliteration of these aneurysms. The occipital artery (OA) is often the preferred donor graft for lesions of the posterior fossa because of its proximity to the target recipient vessels. However, dissectio…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
