HIV related aneurysms are characterised by their predilection for young patients, multiplicity, atypical location and their distinct histological features. Their increasing frequency reflects the unchecked advance of the HIV epidemic.
Carotid aneurysms pose a considerable surgical challenge but are amenable to operative intervention with good result. Ligation appears to be well tolerated in this group of predominantly non-atherosclerotic aneurysms.
initial experience with large-vessel occlusive disease in HIV positive patients suggests an underlying arteritic aetiology, with clinical and pathological features distinct from atherosclerosis. Further in-depth study is necessary to clarify the pathophysiological basis thereof.
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.
