Radial artery versus right internal thoracic artery as the second arterial graft in coronary surgery

Abstract:

Background: The radial artery (RA) has provided the option of substituting the use of the right internal thoracic artery (RITA) in coronary surgery. We retrospectively compared the perioperative and midterm outcomes of patients receiving a RA vs. those receiving a RITA as a second arterial graft. Methods: Between March-96 and Feb-03, 489 patients underwent coronary artery bypass grafting using the RA (399 patients) or the RITA (90 patients) in combination with the left ITA. There was a higher prevalence or risk factors in the RA group (p< 0.05): average age 61±8 vs. 58±9; diabetes mellitus 35% vs. 25%; obesity 17% vs. 9%. Both groups (RA vs. RITA) with similar parameters as three-vessel disease (67% vs. 70%) and average EF (56±20 vs. 54±12). The RA group showed a greater Higgins and Euroscore risk scoring (p< 0.01). Results: In the RA group more coronary artery bypass graftings were performed (p< 0.05 …
