Coronary artery bypass graft surgery is the standard care in the treatment of advanced coronary artery disease. A vascular anastomosis represents a surgical connection between two vessels in which blood can flow. Depending on the surgical objective, the anastomosis can be a created in an end-to-end or end-to-side configuration.
Bypass graft remodeling is a complex process involving many biological and hemodynamic factors. Following CABG surgery, bypass graft failures are classified either as early (common cause is thrombosis) or late (cause is neointimal hyperplasia).
The aim of this study was to determine the three-dimensional flow behaviors that occur at the anastomosis section of the bypass graft, and to investigate the changes that resulted from variations in the anastomosis angle and flow division in the anastomosis site.
