Abstract：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.
