Internal carotid artery bifurcation aneurysms / 国际脑血管病杂志

ABSTRACT

Internal carotid artery bifurcation aneurysm is relatively rare in clinical practice. It locates at the bifurcation of the internal carotid artery, with numerous branches and perforating vessels running through it. Whether endovascular treatment or craniotomy clipping, it is necessary to ensure the patency of the branches and perforating vessels. There are very few systematic reports on internal carotid artery bifurcation aneurysms. This article summarizes its definition, epidemiology, formation and rupture mechanisms, clinical features, and imaging features, with a focus on explaining its classification and treatment.
