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.
