Clinical features and outcomes of PComA aneurysms originating from fetal posterior communicating arteries in a single institution

Abstract

Background: The aim of this study was to retrospectively analyze our experience with the patients who underwent surgical treatment of posterior communicating artery (PComA) aneurysms originating from fetal posterior cerebral artery (fPCA) and analyze the risk factors for the postoperative radiological infarction and outcome. Methods: From 2011 to 2020, we retrospectively reviewed 74 PComA aneurysms originating from fPCA in terms of the clinical and radiological features and obtained the follow-up data from the

Treatment of a ruptured fetal-type posterior communicating aneurysm with a combined approach using the new contour neurovascular system

“…Surgical treatment has a considerable chance of inadvertently injuring the PCom or adjacent perforating arteries. An FPCom tends to be a predictive factor for postoperative infarction, which is estimated to be up to 25.7% 6. Moreover, PCom aneurysms have the second highest rate of intraoperative rupture, after anterior communicating aneurysms, among anterior circulation aneurysms (9.3%) 7.…”
