【摘要】 目的探讨大脑中动脉(MCA)狭窄支架血管成形术的安全性和疗效。方法26例经内科保守治疗无明显疗效的短暂性脑缺血发作或有明显大脑中动脉供血区缺血临床表现的患者,经脑血管造影检查诊断大脑中动脉狭窄后予以支架血管成形术治疗。结果狭窄血管均得到成功的扩张,术前、术后狭窄程度分别为(78.4±6.2)%和(13.4±4.5)%,所有残余狭窄均小于30%,短暂性脑缺血发作症状均得到控制,脑梗死患者症状得到明显改善。结论支架血管成形术是治疗大脑中动脉狭窄的一种安全、有效的治疗方法,其短期疗效肯定,长期疗效有待进一步观察.更多还原

【Abstract】 Objective To value the effect and safety of the endovascular stenting angioplasty for stenosis of middle cerebral artery.Methods We performed percutaneous endovascular stent assisted angioplasty in 26 patients with high-grade stenosis of MCA diagnosised by angiography,who had either recurrent transient ischemic attacks (TIAs) resistant to medical therapy or severe persistent ischemic of MCA.Results Stent placement and angioplasty were successfully performed in all patients .The mean degree of stenosis reduced from(78.4±6.2)% to (13.4±4.5)%,and the degree of residual stenosis were less than 30%.None of the patients developed TIAs ,and the neurologic deficit with ischemic stroke were improved. Conclusion Endovascular stenting for MCA stenosis seems to be a safe and effective theraputic method.Further study is needed for long term outcome.更多还原
