覆膜支架腔内隔绝术治疗外周动脉瘤

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。

Endovascular covered stent-graft exclusion of peripheral aneurysms

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.
