摘　　要：目的:探讨椎-基底动脉延长扩张症(VBD)的临床表现和影像学分型的关系。方法:回顾性分析2008年1月至2014年8月我院收治的VBD31例的临床及影像学资料。结果 :临床表现为后循环缺血9例,脑干压迫8例,颅神经卡压症状5例,脑出血2例,脑积水1例,无症状6例;影像表现为椎基底动脉呈S型、U型和螺旋型迂曲、扩张,基底动脉上端超过鞍上池或床突平面6 mm以上,位置在鞍背或斜坡旁正中至边缘以外,直径大于4.5 mm;S型主要见于无症状患者或表现为脑干压迫,U型主要表现为神经卡压症状,螺旋型主要表现为后循环缺血症状。结论:熟悉VBD的影像学分型和临床症状的关系,有助于对该病进行早期干预、治疗,对评估预后亦有重要指导意义。Objective：To explore the relationship between the clinical manifestations and imaging classification of vertebrobasilar dolichoectasia（VBD）. Methods： The clinical and imaging data of 31 patients with VBD were analyzed retrospectively from Jan 2008 to Aug 2014. Results： Clinical manifestations of posterior circulation ischemia were 9 cases , brain stem compression were 8 cases , cranial nerve compression symptoms were 5 cases , 2 cases were cerebral hemorrhage, 1 cases was hydrocephalus, 6 cases were asymptomatic. Imaging manifestation as vertebrobasilar artery was S type , U type and spiral type tortuosity , dilatation , basilar artery top over the suprasellar cistern or the clinoid plane above 6 mm, position outside the saddle back or slope paramedian to edge, diameter greater than 4.5 mm , and type S was mainly seen in asymptomatic patients or for the performance of brainstem compression , U mainly manifested was nerve compression symptoms, spiral type mainly for posterior circulation ischemia. Conclusion：Familiar with the relationship between the clinical manifestations and imaging classification of VBD , contribute to early intervention, treatment of the disease, but also has important guiding significance for evaluation of prognosis.
