椎基底动脉狭窄血管内支架成形术效果分析

目的 探讨症状性椎基底动脉血管内支架成形术的远期效果.方法 选取症状性椎动脉狭窄接受血管内支架治疗的33例患者,对临床症状和支架内再狭窄情况进行随访观察分析.结果 33例患者支架成形术后临床症状均明显改善,术前平均狭窄率为（92.36±3.23）％,术后即刻平均残余狭窄率为（9.13±2.57）％.术后23例临床症状完全消失,10例明显改善.1例基底动脉重度狭窄患者术后出现一侧肢体麻木的并发症,1例术后出现脑栓塞表现,3d后恢复正常.随访6～24个月,9例出现头晕、头昏等不适症状,其中29例获得数字减影血管造影检查,残余狭窄率为（19.27±5.62）％,3例椎动脉开口支架内再狭窄＞50％,再次给予支架内成形术,症状消失.结论 症状性椎基底动脉狭窄血管内支架成形术能够明显缓解脑缺血症状,提高患者生存质量,同时有一定的再狭窄率.

Clinical analysis of stenting administration on angioplasty of patients with vertebrobasilar artery stenos

Objective To investigate the long-term effect of angioplasty of patients with symptomatic vertebrobasilar artery stent.Methods Thirty-three patients with symptomatic vertebral artery stenosis who underwent endovascular treatment stent.The clinical symptoms and stent restenosis were recorded.Results The clinical symptoms of 33 cases with angioplasty were improved significantly.The preoperative stenosis rate was （92.36 ±3.23）% before operation and the average postoperative residual stenosis rate was （9.13 ±2.57）% after operation.Clinical symptoms of 23 patients disappeared completely after operation,and 10 cases improved significantly.As to complications,1 case with severe basilar artery stenosis had a side numbness of extremities,1 case showed postoperative cerebral embolism,and return to normal after 3 days.When follow up periods lasted for 6-24 months,9 cases were with dizziness or other symptoms.Of which,29 cases were performed DSA imaging,the residual stenosis rate was （19.27 ± 5.62）%,3 cases of vertebral artery in-stent restenosis were reached over 50%.Those 3 cases were give stent angioplasty again and the uncomfortable symptoms disappeared.Conclusion Stenosis opeation can significantly alleviate the symptoms of cerebral ischemia and symptomatic vertebrobasilar artery,and improve the quality of life of patients.However,restenosis should paid more attention.
