The A1-A2 diameter ratio may influence formation and rupture potential of anterior communicating artery aneurysms.


BACKGROUND Specific morphological factors contribute to the hemodynamics of the anterior communicating artery (AComA). No study has examined the role of the A2 segment on AComA aneurysm presence and rupture. OBJECTIVE To examine the possibility that the ratio between A1 and A2 segments (A1-2 ratio) represents an independent risk factor for presence and… (More)
