摘　　要：目的:探讨多层螺旋CT(MSCT)对椎基底动脉延长扩张症(VBD)的诊断价值。方法:对照Smoker标准分析16例VBD的MSCT表现。结果:16例椎VBD中,基底动脉延长与偏移均为2级的12例、3级的4例;基底动脉最大径4.5～7.9 mm,平均(5.07±0.89) mm;脑干受压7例,三脑室受压4例致脑积水1例,急性脑梗死5例(桥脑1例),脑内出血1例,硬膜下血肿1例。结论:MSCT能显示VBD本身及其与周围组织结构的关系,甚至VBD造成的并发症,是目前有效诊断与动态观察VBD的检查方法之一。Objective:To evaluate the value of multi-slice helical computer tomography(MSCT)in the diagnosis of vertebrobasilar dolichoectasia(VBD).Methods:MSCT presentations were examined in 16 cases of VBD according to Smoker's diagnostic criteria.Results:Elongation and deviation of basilar artery occurred in 12 cases(grade 2),and in 4(grade 3).The mean maximal diameter of basilar artery was(5.07±0.89)mm(ranging from 4.5 to 7.9 mm).Brainstem compression was seen in 7 cases,involvement of three ventricles in 4(1 complicated with hydrocephalus),acute cerebral infarction in 5(infraction in pons in 1),intracerebral hemorrhage in 1 and subdural hematoma in another 1.Conclusion:MSCT can clearly display the structure of VBD and involvement of the lesions and surrounding tissues,and even the complications associated with VBD,suggesting that MSCT should be the most effective technique for the diagnosis and dynamic observation of VBD.
