Comprehensive angiographic evaluation of graft quality after endoscopic vein harvesting in coronary artery bypass grafting

Detailed angiographic evaluation revealed that EVH did not compromise graft quality or patency compared with conventional OVH. The incidence of wound complications was very low, and early postoperative SVG-related events were favorable. These findings suggest that EVH is a safe and reliable harvesting technique, providing high-quality grafts with excellent angiographic integrity. Individualized selection of harvesting strategy remains important for optimizing surgical outcomes.
