Abstract

Introduction
Geometrical and hemodynamic factors play major role in aneurysms growth and rupture. This study explores the interplay between different geometrical features of various types of aneurysms related to aneurysm rupture angiographically.
Aim of the work
The aim of this study is to investigate the three-dimensional geometrical features associated with 250 ruptured saccular intracranial aneurysms admitted at the neurosurgery department hospitals, Alexandria University
Patients
This study includes retrospective analysis of 250 cases of ruptured saccular intracranial aneurysms admitted to the neurosurgery department hospitals and affiliated hospitals at Alexandria University.
Methods
3D DSA studies were retrospectively analysed for 180 patients with ruptured SW and SWB aneurysms and 70 patients with ruptured endwall aneurysms, excluding AcoA aneurysms. In SW and SWB cases, relationships between maximum aneurysm depth and different geometrical features including neck diameter, parent vessel curvature angle and diameter difference between proximal and distal parent vessel segments were explored. In EW cases, maximum aneurysm depth was correlated with neck diameter, branching angle and discrepancy between daughter vessel diameters.
