BACKGROUND:Limited by the high financial burden of stent-graft and proof of evident-based medicine, the popularization of endovascular abdominal aortic aneurysm repair, a mini-invasive method, is impeded in China. In order to reduce costs, development of domestic-made stents is imperative, but the relative research is stil rare. OBJECTIVE:To compare the effect of domestic-made stent-graft (Percutek) and Gore Excluder in the endovascular abdominal aortic aneurysm repair. METHODS: From January to November 2014, there were 32 male patients with infrarenal abdominal aortic aneurysm, aged 56-79 years old with mean age of (70.2±6.9) years, admitted in the Vascular Surgery Department of the Affiliated Hospital of Qingdao University. Clinical data were colected and retrospectively analyzed. There were 11 cases undergoing domestic-made stent-graft repair and 21 undergoing Gore Excluder repair. Aortic CT angiography was performed at 1 and 6 months after surgery, and every 6 months thereafter to evaluate the effect of the two modalities. RESULTS AND CONCLUSION: Domestic-made stent-grafts were successfuly implanted into the 11 patients, and there were 1 case of late type I endoleak, 1 of type II endoleak, 1 of iliac occlusion and 1 of death after surgery. Totaly 11 stent-graft trunks, 18 iliac stent-grafts, 1 Cuff, and 1 bare metal stent were implanted in the domestic-made stent-graft group (2.8 stents/case). Totaly 21 patients were subjected to Gore Excluder repair with the success rate of 90%, and 2 cases of intraoperative I type endoleak (10%), 2 of postoperative I type endoleak and 2 of postoperative II type endoleak were observed. Totaly 21 stent-graft trunks, 28 iliac stent-grafts and 3 Cuff were implanted in the Gore Excluder group (2.47 stents/case). These results suggest that the novel domestic-made stent-graft has achieved a satisfactory outcome in endovascular abdominal aortic aneurysm repair, showing no significant differences in related indicators with the Gore Excluder; however, the long-term outcomes stil need to be further studied.%背景：受限于高昂的覆膜支架费用和有限的循证医学数据，腹主动脉瘤腔内修复术这一微创技术在国内的普及受到阻碍。为了降低费用，覆膜支架材料的国产化势在必行，但是之前国产腹主动脉瘤覆膜支架的循证医学数据仍然较少。目的：对比新型国产腹主动脉覆膜支架与进口覆膜支架(GORE EXCLUDER)腔内修复治疗腹主动脉瘤的效果。方法：回顾性分析2014年1至11月在青岛大学附属医院血管外科完成腹主动脉瘤腔内修复术32例肾下型腹主动脉瘤患者的临床资料，其中采用国产覆膜支架(华脉泰科)11例，GORE EXCLUDER覆膜支架21例。患者均为男性，年龄56-79岁，平均(70.2±6.9)岁。于术后第1，6个月及之后每6个月行主动脉计算机断层扫描血管造影检查评估治疗效果。结果与结论：①国产组支架组11例均成功植入华脉泰科覆膜支架，术后发现迟发Ⅰ型内漏1例，Ⅱ型内漏1例，1例术后髂支闭塞，1例死亡。共植入覆膜支架主体11枚，髂动脉覆膜支架18枚，Cuff支架1枚，裸支架1枚，平均2.8枚/人；②进口支架组21例均成功植入GORE EXCLUDER覆膜支架，技术成功率90%，术中造影发现Ⅰ型内漏2例(10%)，术后复查发现Ⅰ型内漏2例，Ⅱ型内漏2例。共植入覆膜支架主体21枚，髂动脉覆膜支架28枚，Cuff支架3枚，平均2.47枚/人；③结果表明，新型国产腹主动脉覆膜支架治疗肾下腹主动脉瘤取得了满意的近-中期疗效，各观测指标与进口支架组差异无显著性意义。但是国产覆膜支架的远期疗效仍有待进一步研究。
