The mortality and morbidity of aneurysms treated in our department, both unruptured and ruptured, were relatively low and comparable with the results presented in the literature. The number of unruptured aneurysms with visual dysfunction was not as high as reported in the literature, but our results correlate with the main conclusion of those studies: to treat those aneurysms surgically when possible and within three months from the start of symptoms.
This study presents a rare case of subarachnoid hemorrhage (SAH) caused by an aneurysm formation on the posterior communicating artery (P Com), adjacent to the junction with the P1 branch in a patient with a long-lasting, bilateral occlusion of the internal carotid arteries (ICA). Furthermore, we discuss the incidence of aneurysm formation in idiopathic occlusion of the ICA. Ã
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.
