Abstract

Introduction :
Anterior communicating artery "AcoA" aneurysms are considered highly complex due to their intricate vessel geometry and blood flow conditions. This study explores the morphological parameters related to rupture of AcoA aneurysms as observed angiographically.


Aim of the work
This study aims to identify common geometrical characteristics associated with rupture of AcoA aneurysms at the Alexandria main hospital and affiliated hospitals, Alexandria University.


Patients
This study includes a retrospective analysis of 200 cases of ruptured anterior communicating artery aneurysms admitted at the neurosurgery department at Alexandria University hospitals.

Methods:
Analysis for 200 patients diagnosed with ruptured AcoA aneurysms was conducted using 3D angiographic studies. AcoA aneurysms were classified according to A1 predominance into dominant and true types. The correlations between rupture of both types of AcoA aneurysms and A1-A2 diameter discrepancy, and A1-A2 angle narrowing were investigated. Additionally, the correlation between maximum aneurysm depth and aneurysm neck was recorded.
