摘　　要：目的探讨椎基底动脉扩张延长症(VBD)的CT血管造影(CTA)影像学特点及临床表现。方法回顾性分析30例VBD患者的影像学及临床资料,根据椎基底动脉CTA形态进行影像学分型,并与对照组(30例)比较后循环脑梗死及血管狭窄的发生率。结果 (1)根据VBD在CTA上的表现,分为:S型、U型/L型、螺旋型;S型临床症状最轻,U型/L型次之,螺旋型最重。(2)30例VBD患者中,后循环脑梗死12例,血管狭窄8例,对照组分别为5例、17例,2组间后循环脑梗死及血管狭窄的发生率差异有统计学意义(P<0.05)。结论CTA可以对VBD进行分型,各型影像学及临床表现各异。VBD与后循环脑梗死关系密切。Objetive To evaluate the imaging characteristics and clinical manifestations of CT angiography in vertebrobasilar dolichoectasia(VBD).Methods The imaging and clinical data of 30 patients with VBD were retrospectively analyzed.The imaging of CTA was performed according to the morphology of vertebrobasilar CTA,and the incidence of cerebral infarction and vascular stenosis was compared with the control group(30 cases).Results(1)According to the performance of VBD on CTA,it is divided into:S type,U type/L type,spiral type;S type clinical symptoms are the lightest,U type/L type is the second,and spiral type is the heaviest.(2)Among the 30 patients with VBD,12 patients had posterior circulation cerebral infarction,8 patients had vascular stenosis,and 5 patients in the control group,17 patients.There was a statistically significant difference in the incidence of posterior circulation cerebral infarction and vascular stenosis between the two groups(P<0.05).Conclusion CTA can be used to classify VBD,and each type of imaging and clinical performance varies.VBD is closely related to posterior circulation cerebral infarction.
