Underlying mechanisms of saphenous vein graft stenosis after coronary artery bypass caused by clipping of the side branches: an experimental study.

ABSTRACT:

Background

Saphenous veins are regular bypass conduits selected in non-left anterior descending artery (LAD) coronary artery bypass graft (CABG) surgery. Despite the technical errors, acute thrombosis, intimal hyperplasia and arteriosclerosis which could lead to saphenous vein graft (SVG) failure, the metal-clipping-related SVG failure is unique and rare. This study was conducted to investigate the clinical and underlying mechanisms of the metal-clipping-related SVG failure.

Methods

We collected 6 typical cases of the metal-clipping-related SVG failure in 41 patients who were diagnosed graft stenosis by coronary angiograph after CABG in the Department of Cardiology, Beijing Anzhen Hospital, from January 2020 to September 2021. Furthermore, we built an in vitro model t
