Covered stent graft by entrapping the thrombus between the vessel wall and stent might be helpful in preventing distal embolization and "no reflow" in a high-risk patient cohort. We here present a case with successful restoration of coronary flow in a highly thrombogenic milieu (acute myocardial infarction) with implantation of two covered stent grafts which by entrapping the thrombus avoided the distal embolization and "no reflow" in a totally occluded saphenous vein graft (SVG). However, stent length should be longer than the measured lesion length since choosing the exact diameter will not cover the plaque elongification secondary to the dilation process which is specifically significant in SVGs because of the softness of the plaque.
通过将血栓困在血管壁和支架之间的覆膜支架移植物，可能有助于在高危患者群体中预防远端栓塞和“无复流”现象。我们在此展示一例病例，在高度血栓形成的环境（急性心肌梗死）中，通过植入两枚覆膜支架移植物成功恢复了冠状动脉血流，这两枚支架移植物通过困住血栓，避免了在完全闭塞的大隐静脉桥血管（SVG）中发生远端栓塞和“无复流”。然而，支架长度应长于测量的病变长度，因为选择精确的直径无法覆盖由于扩张过程导致的斑块延伸，这在SVG中尤为显著，因为斑块质地柔软。
