Objective To investigate the clinical and imaging features of vertebrobasilar dolichoectasia (VBD). Methods The clinical data of a patient with VBD was analyzed retrospectively. Results The patient occurred as headache, vomiting, disturbance of consciousness, hemiplegia, hydrocephalus and brain stem infarction performance. Imaging examination displayed ventricular enlargement, hydrocephalus and pontine infarction. The extension and expansion of the basilar artery extend to third ventricle were seen by CT, MRI, CTA, DSA inspection.The symptom remissed by antihypertensive treatment after the first onset, and the CT showed significantly reduced of lateral ventricle. Conclusions VBD can occur the manifestation of hydrocephalus and posterior circulation ischemia.Imaging can demonstrate extension and expansion of the basilar artery. Control high blood pressure can alleviate the symptom of VBD.%目的:探讨椎-基底动脉延长扩张症(VBD)的临床及影像学特点.方法:回顾性分析1例VBI)患者的临床资料.结果:本例患者先后出现头痛、呕吐、意识障碍、偏瘫,脑积水和脑干梗死的表现.影像学检查分别提示侧脑室扩大、脑积水和脑桥梗死.CT、MRI、CTA、DSA检查均见椎-基底动脉延长扩张、深入至第三脑室.首次发病后经降血压治疗,症状缓解,头颅CT示侧脑室明显缩小.结论:VBD可出现脑积水和后循环缺血的临床表现.影像学检查显示延长扩张的椎-基底动脉.控制高血压对本病有缓解作用.
