Proposed Parent Vessel Geometry Based Classification of Anterior Communicating Artery-Located Aneurysms.

Background And Objectives: The present study is focused on correlation of parent vessels and neck diameters with anterior communicating artery (AComA) aneurysmal depth and growth direction. The study principally aims to suggest a new classification of AComA-located aneurysms based on the physical characteristics of parent vessels.

Methods: A retrospective analysis was performed of 155 patients with ruptured AComA-located aneurysms.
