Clinical analysis of stenting administration on angioplasty of patients with vertebrobasilar artery stenos / 中国综合临床

ABSTRACT

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.
