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.
