The current gold standard of popliteal artery aneurysm (PAA) treatment is saphenous vein bypass grafting. The aim of this retrospective single-center study is to investigate the safety and efficacy in the treatment of PAA by an endovascular implanted covered endoprosthesis.
Ten patients, mean age 64.6 (range, 52-78) years, with PAA were treated with an expanded Polytetrafluoroethylen (ePTFE)-covered stent graft (Viabahn(®), W.L. Gore and Associates Inc, Flagstaff, AZ, USA). In median, 1.4 prostheses were implanted with a median length of 180 mm. Follow-up visits included determination of ankle-brachial index (ABI) and color-coded duplex sonography.
The technical success rate was 100% (10/10). Clinically, there was an increase in ABI from 0.62 ± 0.17 to 0.91 ± 0.15 postinterventionally and to 0.89 ± 0.16 after an average follow-up of 24.7 months. During the follow-up period, 2 (20%) stent occlusions occurred; both of them were treated with a bypass graft.
The treatment of PAA with covered endoprosthesis is a safe and effective alternative to open surgical therapy, where open surgical therapy is contraindicated or patient refused open surgery.
目前腘动脉动脉瘤（PAA）治疗的金标准是大隐静脉旁路移植术。本回顾性单中心研究的目的是调查血管腔内植入带膜血管内支架治疗PAA的安全性和有效性。
10例PAA患者，平均年龄64.6岁（范围52 - 78岁），采用膨体聚四氟乙烯（ePTFE）覆膜支架移植物（Viabahn®，美国亚利桑那州弗拉格斯塔夫市W.L. Gore及合伙人公司）进行治疗。平均植入1.4个假体，中位长度为180 mm。随访包括测定踝肱指数（ABI）和彩色编码双功超声检查。
技术成功率为100%（10/10）。临床上，干预后ABI从0.62±0.17增加到0.91±0.15，平均随访24.7个月后增加到0.89±0.16。随访期间发生2例（20%）支架闭塞；均采用旁路移植术治疗。
对于开放手术治疗禁忌或患者拒绝开放手术的情况，带膜血管内支架治疗PAA是一种安全有效的替代开放手术治疗的方法。
