摘　　要：小口径人工血管与宿主血管间顺应性不匹配,是导致其植入后远期通畅率低的重要因素;而目前已有文献证明,腔内隔绝术用覆膜支架(SG)与宿主血管间顺应性不匹配,也是引起术后远期滑移、内漏、血流紊乱等并发症的原因。但是,这一领域的研究十分有限。综述SG顺应性的评价方法,包括通过SG体积、压力的变化计算其体积顺应性,或通过脉搏波速和瘤体压力间接反映SG的顺应性。关于SG顺应性的研究主要包括:验证SG的植入对宿主血管的影响,不同结构SG对宿主血管的影响,以及顺应性随疲劳时间推移的可能变化。同时,对改变结构优化SG顺应性进行简要综述。Compliance mismatch between small diameter vascular graft and host artery is the main factor caused low long-term patency rate. There are literatures proving that compliance mismatch between endovascular stent graft and host artery is the main reason caused the long-term complications, such as SG displacement,endoleaks and blood turbulence. However there is only limited number of studies in this area at present. This article reviewed the methods of evaluating compliance of SG,including calculating via pressure range and corresponding SG volume change or reflecting indirectly by pulse wave velocity and aneurysm pressure.Researches on SG compliance mainly include verifying effects of SG implantation on host artery,effects of different SG structures on host artery,and how compliance changing over time. Achieving compliant SG by optimizing SG structure is reviewed briefly.
