文题释义:
覆膜支架
:又称人工支架型血管移植物,由起固定作用的金属龙骨支架和不透血液的覆膜材料组成,不同厂家的覆膜支架在设计理念、固定方式、材料使用、适应证等方面不尽相同,因此术后的治疗效果以及所产生的并发症也不同。
腹主动脉瘤腔内修复术:是通过植入人工支架型血管移植物用以腔内隔绝腹主动脉瘤,进而达到预防或者治疗动脉瘤破裂的一种微创、便捷、安全的新手术方式,其推广使用的主要受限因素为腹主动脉瘤的解剖条件和高昂的材料费用。

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。

Abstract:

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 still 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 collected 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 successfully 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. Totally 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). Totally 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. Totally 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 still need to be further studied.
