摘要
目的探讨经皮腔内血管成形和支架植入术治疗椎基底动脉狭窄的效果和安全性。方法2003年4月至2004年6月,对28例椎基底动脉狭窄患者进行了经皮腔内血管成形和支架植入术治疗;随访观察治疗效果和不良反应。结果28例患者,18例为优势侧椎动脉狭窄,4例为双侧椎动脉狭窄,3例为一侧椎动脉狭窄、对侧椎动脉闭塞,1例为串联狭窄,2例为基底动脉狭窄。狭窄段位于椎动脉开口9例,位于颈部椎动脉2例,位于颅内段17例。Mori A型病变24例,B型病变3例,C型病变1例。全组技术成功率100%,术前28例平均狭窄率为81.3%,术后残余狭窄率均<10%。所有病例在围手术期内均未发生严重并发症。本组随访17例患者,时间为6个月,M alek评分为1分者15例,2分者2例。其中3例经DSA脑血管造影复查均未见支架内再狭窄。结论经皮腔内血管成形和支架植入术是治疗椎基底动脉供血不足、预防椎基底动脉系统卒中的安全和有效方法。
Objective To investigate the effectiveness, safety of the percutaneous transluminal angioplasty and stenting （PTAS） in the management of the vertebrobasilar stenosis. Methods From April 2003 to June 2004, the PTAS was performed in 28 patients with the vertebrobasilar stenosis. Results Among the 28 patients, the unilateral significant stenosis of the dominant vertebral artery was found in 18 patients, the bilateral stenosis of the vertebral artery in 4 patients, the tandem stenosis of the vertebral artery in 1 patient, the stenosis of the basilar artery in 2 patients. According to Mori＇ s division, the type A occurred in 24 patients, the type B in 3 patients, the type C in 1 patient. The successful rate of stent implantation was 100% without any serious complication. Twenty-eight patients underwent PTAS with a mean pre-procedural vertebrobasilar stenosis of 81.3% and the residual stenosis was less than 10%. Over a mean 6-month follow-up in 17 patients, according to Malek＇ s scale, the scale 1 was in 15 patients, the scale 2 in 2 patients. No restenosis was in 3 patients by the cerebral angiography. Conclusion PTAS in the management of the vertebrobasilar stenosis is a safe and effective method. Meanwhile, PTAS may alleviate the vertebrobasilar ischemia and prevent stroke of the vertebrobasilar system.
