摘　　要：目的分析椎基底动脉延长扩张症(VBD)的临床表现,探讨MR在椎基底动脉延长扩张症的诊断价值。方法回顾性分析我院2006年3月至2012年3月确诊的28例VBD患者的临床表现及MR特点,所有患者行头颅MRI扫描及磁共振血管造影(3D-TOF MRA)检查。结果椎基底动脉供血不足及脑梗塞13例;脑干压迫7例;脑神经压迫症状5例;脑出血5例;脑积水2例。所有患者基底动脉和(或)椎动脉最大直径超过4.5 mm,其中最大直径达到8.3 mm,基底动脉向右迂曲19例,向左迂曲9例;椎动脉单纯型23例,骑跨型5例。结论椎基底动脉扩张延长症最主要临床表现为后循环缺血或梗死,其他表现有脑干受压、脑神经损害、脑出血及脑积水等,无特异性。VBD主要依靠影像学诊断,磁共振可作为VBD诊断的首选检查方法 。Objective To assess the clinical and MR features of vertebrobasilar dolichoectasia （~BD）. Methods The clinical records of 28 patients with diagnosis of VBD from March 2006 through March 2012 in our hospital were analyzed retrospectively. All of the patients underwent MRI and magnetic resonance angiography （MRA）. Results The patients suffered from cerebral infarction （13）, brainstem compression （7）, cranial nerve compression （5）, cerebral hemorrhage （5）, or hydrocephalus （2）. There were 2 types of VBD ： simple （n = 23） and saddle （n = 5）. In all patients, the maximum diameters of the basilar and/or vertebral arteries were greater than 4.5 mm with the greatest diameter of 8.3mm. of 28 patients, the tortuous basilar arteries coursed from left to right in 19 and from right to left in 9. Conclusions The clinical manifestations of VBD are variable. MRI and MRA are valuable for diagnosing VBD.
