Vascular Geometry Associated with Anterior Communicating Artery Aneurysm Formation.

ABSTRACT:

Objective

To identify clinical and morphologic risk factors correlated with anterior communicating artery (ACoA) aneurysm formation.

Methods

Three-dimensional morphologic parameters obtained from computed tomography angiography or digital subtraction angiography from 504 patients with ACoA aneurysms and 201 patients with aneurysms in other locations that were diagnosed at Brigham and Women's Hospital and Massachusetts General Hospital between 1990 and 2016 were evaluated. The presence of hypoplastic and aplastic A1 segments and diameters and angles of surrounding parent and daughter vessels were examined. Univariable and multivariable statistical analyses were performed to determine statistical significance. Sensitivity analyses for small (≤3 mm) aneurysms only were also per
