Three dimensional geometrical features of intracranial aneurysms at the time of rupture; saccular aneurysms

Abstract

Geometric factors such as PV curvature angle, neck width, and PV distal narrowing could affect the risk of growth and rupture of SW and SWB aneurysms. A wider branching angle could be considered in the early rupture of EW aneurysms. Neck width could be significantly related to the growth and rupture of both SW and EW intracranial aneurysms.
