Abstract

BACKGROUND: The suitability of the radial artery after transradial catheterization as a bypass conduit has been of great concern to surgeons.

METHODS: A total of 67 patients underwent isolated coronary artery bypass grafting using the radial artery: 22 patients received preoperative transradial catheterization (group 1) and 45 patients did not receive transradial catheterization (group 2). Those patients were retrospectively reviewed.

RESULTS: Patient characteristics, operative procedures, and early clinical outcome were not different between groups. The stenosis-free graft patency rates in groups 1 and 2 were 88% (16 of 18 patients) and 90% (38 of 42 patients) in the left internal thoracic artery (p = 0.87); 77% (17 of 22 patients) and 98% (48 of 49 patients) in the radial artery (p = 0.017); and 87% (13 of 15 patients) and 84% (21 of 25 patients) in the saphenous vein (p = 0.42), respectively. Intimal hyperplasia of the radial artery was observed in 68% (11 of 16 patients) in group 1 and in 39% (14 of 34 patients) in group 2 (p = 0.046).

CONCLUSIONS: Transradial catheterization reduced early graft patency and caused intimal hyperplasia, although it did not affect early clinical outcomes. We suggest that the use of the radial artery as a bypass conduit after transradial catheterization should be undertaken cautiously.
