Objective To investigate the feasibility and safety of covered stent implantation in treating the peripheral aneurysm and arterial dissection. Methods During the period from Nov. 2008 to May 2012, a total of 24 patients with peripheral vascular diseases were treated in the hospital. The lesions included subclavian arterial pseudoaneurysm (n = 10), iliac arterial dissection (n = 5), iliac arterial pseudoaneurysm (n = 4), iliac arterial aneurysm (n = 3), internal carotid aneurysm (n = 1) and multiple arterial aneurysms of lower extremity (n = 1). After the diagnosis was confirmed with angiography that was performed through catheterization via femoral artery, the implantation of covered stent to isolate the lesions was carried out in all patients. The clinical results were analyzed. Results Covered stent placement was successfully performed in all the 24 cases, and the instant isolation effect was quite satisfactory. During the follow-up period of 2-24 months, no stent - related complications occurred in all patients except one patient with subclavian arterial pseudoaneurysm, who developed pseudoaneurysms at both ends of the inserted stent four months after the initial stent treatment and stent placement had to be carried out once more. Conclusion For the treatment of peripheral aneurysm and arterial dissection, endovascular exclusion with covered stent is a minimally -invasive, safe and effective method.(J Intervent Radiol, 2013, 22: 031-035)%目的 探讨覆膜支架在外周动脉瘤及动脉夹层治疗中的可行性及安全性.方法 2008年11月至2012年5月收治24例外周血管病变患者,其中锁骨下动脉假性动脉瘤10例、髂动脉夹层5例、髂动脉假性动脉瘤4例、髂动脉瘤3例、颈内动脉瘤1例、下肢多发动脉瘤1例.所有患者在经股动脉穿刺血管造影明确病变后,植入覆膜支架行腔内隔绝术.结果 所有患者均成功植入覆膜支架行腔内隔绝治疗,即时封闭效果满意,无手术相关并发症.随访2～42个月,有1例锁骨下假性动脉瘤患者在覆膜支架植入后4个月时支架两端又出现假性动脉瘤,再次植入覆膜支架,其余23例患者均未出现相关并发症.结论 覆膜支架腔内隔绝术是一种微创、安全且高效的外周血管完整性修复方法.
