Angles between A1 and A2 Segments of the Anterior Cerebral Artery Visualized by Three-dimensional Computed Tomographic Angiography and Association of Anterior Communicating Artery Aneurysms

Abstract

ACoA aneurysms are associated with the smaller A1-A2 angle junction of the ACoA complex, where higher hemodynamic stress may occur in patients with normoplastic A1 segments.
