Abstract:

Objective To probe into the endovascular stent angioplasty in the treatment of symptomatic middle cerebral artery stenosis, and evaluate its safety and therapeutic effect. Methods A retrospective analysis of the patients with middle cerebral artery stenosis who had received endovascular stent angioplasty treatment from May 2008 to December 2015 in Neurology Department, Cangzhou City People's Hospital was made to observe the success rate of endovascular stent, surgical complication rate, preoperative and postoperative stenosis stent rate, and follow-up the therapeutic effect of patients who had endovascular stent angioplasty. Results A total of 98 patients who have been successfully implanted brackets were enrolled into the group. The preoperative stenosis rate was (83.8±7.9)% on average, and postoperative residual stenosis rate was (21.9±4.2)%. There was 1 case (1.0%) of subacute thrombus which happened 3 days after the operation, with the restenosis rate of 12.9%. The 1 year follow-up cumulative incidence of endpoint events (onset of ischemic stroke at 30 d after operation, hemorrhagic stroke and operation associated death, ischemic stroke within the lesion region after 30 d) was 14.3%. Conclusion Endovascular stent angioplasty shows good therapeutic effect and safety, high success rate of the operation, and low incidence of 1 year restenosis.
