     【摘要】目的应用数字减影主动脉弓及全脑血管造影方法观察老年椎基底动脉供血不足患者的血管结构异常表现，探讨其在临床上的应用价值。方法对3年来收治的41例老年椎基底动脉供血不足患者行数字减影血管造影检查，并进行综合分析。结果 41例老年椎基底动脉供血不足的患者中，共有32例(780%)患者存在颈及颅内血管结构异常：其中单纯前循环病变4例(98%)；后循环病变28例(683%)；其余9例(220%)造影未见血管结构异常。除1例患者在造影过程中出现短暂的椎动脉痉挛外未出现其它严重并发症。结论后循环血管结构异常是最常见的导致椎基底动脉缺血的血管性病因，前循环狭窄亦是致病因素之一。数字减影血管造影是椎基底动脉供血不足安全准确的检查手段，有助于临床诊断和治疗选择。

    【Abstract】 Objective To observe the incidence of abnormal vascular structures in elderly patients with vertebrobasilar arterial insufficiency(VBI) with digital subtraction angiography(DSA) and to study the clinical value of DSA in VBI Methods Fortyone elderly patients with VBI were all examined with DSA to detect the quantity, types and locus of abnormal vascular structures Resukts Abnormal vascular structures in neck and brain were detected in 32 patients(780%),which included 4 patients(97%)with procyclic lesion only and 28 patients(683%) with postcyclic lesion Other 9 patients(220%) showed no abnormal blood vessel Conckusions The procyclic stenosis ,such as the postcyclic abnormal structure, is frequently to be detected in vertebrobasilar ischemia,DSA is an effective and safe method for the diagnosis of VBI. ......
