目的 探讨对外科高危的症状性颈动脉狭窄患者采用直接内支架成形术治疗的安全性及并发症。方法 对 9例 (11支血管 )外科高危的症状性颈动脉狭窄进行了内支架成形术治疗 ,随访 1～ 5个月 (平均 3个月 ) ,观察术中及术后并发症。结果 9例 (11支血管 )的内支架植入手术成功率为10 0 %。术中及术后随访 ,支架开通良好 ,无短暂性脑缺血发作 (TIA)及卒中发生 ,脑缺血症状消失 ,无围手术期严重并发症。结论 直接内支架成形术治疗高危症状性颈动脉狭窄是一种可以采用的治疗方法 ,但还需进一步临床积累
Objective To investigate the safety and complications of direct stent-graft in surgical high-risk patients with symptomatic carotid stenosis. Methods 9 cases (11 vessels) of surgical high-risk symptomatic carotid stenosis were treated by endovascular stenting. The patients were followed up for 1 to 5 months (average 3 months). The intraoperative and postoperative complications were observed. Results The success rate of stent implantation in 9 cases (11 vessels) was 100%. During the operation and postoperative follow-up, the stent was well opened without transient ischemic attack (TIA) and stroke, and symptoms of cerebral ischemia disappeared without serious complications during perioperative period. Conclusions Direct stenting for the treatment of high-risk symptomatic carotid stenosis is a viable treatment but requires further clinical benefit
