目的研究择期血管内支架成形术治疗症状性颅外动脉狭窄的远期临床疗效。方法对36例弓上颅外动脉狭窄的患者(40处病变)行血管内支架成形术治疗。临床随访观察4～33个月,平均18个月。结果颅外动脉内支架成形术的技术成功率100%,血管狭窄由术前(72.12±8.86)%下降至术后(10.12±6.17)%。围术期内,1例(2.78%,1/36)发生原狭窄供血区轻微缺血性卒中,其余患者未发生手术相关并发症;临床随访无卒中复发或死亡,CT造影随访1例支架内轻度再狭窄。结论血管内支架成形术治疗弓上颅外动脉狭窄远期疗效良好。
Objective To study the long-term clinical efficacy of elective endovascular stenting in the treatment of symptomatic extracranial arterial stenosis. Methods Thirty-six patients (40 lesions) with extracranial extracranial artery stenosis underwent endovascular stenting. Clinical follow-up observation of 4 to 33 months, an average of 18 months. Results The technical success rate of extracranial stent was 100%. The stenosis of blood vessel decreased from 72.12 ± 8.86% before operation to 10.12 ± 6.17% after operation. During the perioperative period, one case (2.78%, 1/36) had mild ischemic stroke in the original stenosis donor area, and the other patients did not have surgery-related complications. There was no recurrence or death after clinical follow-up. One case of CT angiography was followed up Slight restenosis. Conclusion Endovascular stenting has good long-term efficacy in the treatment of extracranial extracranial arterial stenosis.
