支架辅助血管成形治疗椎动脉起始部狭窄

Stenosis at Original Vertebral Treated by Stent Assisted Angioplasty

目的:探讨支架置入治疗椎动脉起始部狭窄的疗效。方法:对9例椎动脉起始部狭窄患者,实施血管内支架置入。结果:患者血管狭窄程度从术前的平均78%下降到术后的3%。除1例术后症状加重外,其余8例未出现任何与操作有关的并发症。术后颈部超声示椎动脉收缩期血流峰值流速从术前的平均215cm/s下降到术后的105cm/s,舒张期末最低流速从70cm/s下降到45cm/s,血流动力学都得到明显的改善。术后随访1～20个月,除1例未变化,其余8例临床症状改善,超声未见再狭窄。结论:支架辅助血管成形治疗椎动脉粥样硬化性狭窄是可行、安全、有效的方法,临床及影像短期效果较好。

Objective： Discuss the curative effection of the patients who was disposed stent at original vertebral artery stenosis section. Methods： Nine patients who had stenosis at original vertebral artery were treated by intravenous stent disposation. Results： All stenosis section had obvious improvement. The degree of stenosis reduced from average 78% preoperatively to 3% postoperatively. Eight patients didn＇t appear any complication relevant of operation except 1 patient＇s syndrom aggravated after operation. Systole peak velocity of vertebral artery ultrasound investigation reduce from 215cm/s before operation to 105cm/s after operation, the lowest velocity of the end of distole reduced from 70cm/s to 45cm/s, blood dynamics got apparently improvement. After clinically followed up （1 - 20 months）, eight patients had obvious improvement with 1 patient no change. No restenosis were found by ultrasound investigation. Oonclusion： Stent assisted angioplasty is an effective and safe treatment for vertebral arteriosclerotic stenosis diseases. A good outcome and imaging could be obtained within short periods.
