Covered stent graft for primary PTCA of an aortocoronary vein graft

Abstract

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.
