摘要

椎基底动脉硬化症（VBD）是一种导致椎基底动脉病理性伸长、扭曲和扩张的动脉疾病。多发于大脑后循环，但也可发于大脑前循环；基底动脉占80%以上。由于基底动脉以大角度发出多个分支，并且分支点处的剪切力较大，因此可能发生VBD[1，2]。病例报告

Acute subarachnoid hemorrhage due to giant vertebrobasilar dolichoectasia

Vertebrobasilar dolichoectasia (VBD) is an arteriopathy resulting in pathological elongation, twisting, and dilatation of the vertebrobasilar artery. Dolichoectasia mostly occurs in the posterior cerebral circulation, but it can also occur in the anterior cerebral circulation; the basilar artery is involved in >80% of cases. As the basilar artery gives off several branches at large angles, and the shearing forces are greater at the branching points, VBD can occur [1,2]. CASE REPORT
