颈内动脉分叉部动脉瘤

Internal carotid artery bifurcation aneurysms

颈内动脉分叉部动脉瘤在临床上相对罕见,其位于颈内动脉终末分叉处,其间有众多分支和穿支血管走行。无论血管内治疗还是开颅夹闭手术,均需要保证分支及穿支血管的通畅。关于颈内动脉分叉部动脉瘤的系统性报道极少。文章总结了其定义、流行病学、形成和破裂机制、临床特征以及影像学特征,并重点阐释了其分类和治疗方法。

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.
