Enhancing Radial Artery Graft Patency: Perioperative Strategies and Clinical Insights in Coronary Artery Bypass Surgery

With the widespread adoption of multiple and total arterial coronary artery bypass grafting, the radial artery (RA) has regained favor among cardiac surgeons. The advent of antispasmodic medications, improvements in surgical techniques, and the selection of more suitable target conduits have led to numerous studies demonstrating significantly higher patency rates for the RA, thus broadening its application. This review discusses the historical development of arterial bypass grafts, the current use of the RA, and the effectiveness of perioperative management in maintaining the viability of the RA as a graft. It also addresses strategies to minimize perioperative factors that could impair the RA, thereby ensuring graft quality.
