目的 探讨外周动脉瘤应用覆膜支架腔内隔绝术治疗的疗效和安全性.方法 对12例外周动脉瘤(真性动脉瘤5例,假性动脉瘤7例)患者行经股动脉穿刺插管造影,之后于病变部位放置覆膜支架行腔内隔绝术.结果 12例成功进行外周动脉瘤覆膜支架腔内隔绝术,其中11例动脉瘤腔完全封闭隔绝,1例动脉瘤治疗后有内漏,无手术相关并发症,即刻造影示置入覆膜支架远端动脉均血流通畅.随访观察3 ～ 36个月,无动脉瘤复发及动脉瘤相关并发症发生,1例3个月后发生覆膜支架腔内闭塞.结论 覆膜支架腔内隔绝术治疗外周动脉瘤是一种创伤小、安全易行、疗效确切的治疗方法.%Objective To discuss the efficacy and safety of endovascular covered stent-graft exclusion for the management of peripheral aneurysms. Methods Twelve patients with peripheral aneurysms, including true aneurysms (n = 5) and pseudoaneurysms (n = 7) were enrolled in this study. By using Seldinger technique, catheterization via femoral artery was performed, which was followed by angiography to demonstrate the diseased site. The covered stent-graft was then implanted in the diseased site to complete the endovascular exclusion. Results Endovascular covered stent-graft exclusion of peripheral aneurysms was successfully performed in all 12 cases. The aneurysm was completely isolated in 11 cases, and endoleak was observed in 1 case. No procedure-related adverse effect or severe complications occurred. Angiography performed immediately after the procedure showed that the artery distal to the stent-graft was well patent. All the patients were followed up for 3-36 months, no recurrent aneurysms or related complications were observed. In-stent occlusion was seen in 1 case 3 months after the procedure. Conclusion Endovascular covered stent-graft exclusion of peripheral aneurysms is a minimally-invasive, safe, simple and effective technique. (J Intervent Radiol, 2012, 21: 107-110)
