目的:探讨血管内支架成形术治疗大脑中动脉狭窄的疗效及安全性。方法:对22例大脑中动脉狭窄患者行血管内支架成形术,回顾性分析其临床特点、疗效及治疗经验。结果:22例患者共植入22枚支架,均获得成功。术后即刻造影狭窄率为(11.2±4.5)%,较术前(79±15)%明显改善。术后残余狭窄程度均小于20%。临床随访无TIA发作或脑卒中再发,DSA随访除1例外均无再狭窄发生。结论:血管内支架成形术治疗大脑中动脉狭窄安全有效,但远期疗效还需进一步观察。
Objective: To investigate the efficacy and safety of endovascular stenting in the treatment of middle cerebral artery stenosis. Methods: Twenty - two patients with middle cerebral artery stenosis underwent endovascular stent angioplasty. The clinical features, therapeutic effects and treatment experience were retrospectively analyzed. RESULTS: A total of 22 stents were implanted in 22 patients and were successful. Immediate postoperative angiography stenosis rate was (11.2 ± 4.5)%, compared with preoperative (79 ± 15)% was significantly improved. Postoperative residual stenosis were less than 20%. No clinical follow-up TIA attack or stroke recurrence, DSA follow-up with 1 exception, no restenosis occurred. Conclusion: Endovascular stenting is safe and effective in the treatment of middle cerebral artery stenosis. However, long-term efficacy needs further observation.
