Optimum incision geometry in side-to-side anastomosis.

ABSTRACT: In coronary artery bypass grafting (CABG), the use of a saphenous vein (SV) graft to the left anterior descending (LAD) artery is prevalent. While end-to-side anastomosis (ESA) is considered standard practice, several studies have highlighted the effectiveness of side-to-side anastomosis (SSA). Optimizing the cross-sectional geometry is one of the factors influencing the success of the anastomosis. Among the possible configurations, an elliptical cross-section is the most suitable option because of its smooth perimeter and its ability to prevent stress concentration. The optimal diameter ratio for this elliptical cross-section can be determined through an optimization process. This study investigated the impact of punch geometry on the side-to-side anastomosis (SSA) at a 90-degree grafting
