Abstract
Despite a revival of interest in using the radial artery as an alterna tive conduit for myocardial revascularization, little angiographic doc umentation of early postoperative results has been presented, particul arly in North America. Accordingly, 60 of 150 patients who underwent c oronary artery bypass with radial arteries from November 1993 to July 1995 have had postoperative cardiac catheterization at our institution . The patency rate of the radial artery grafts was 95.7% (90 of 94 gra fts patent) with an average internal diameter of 2.51 mm. Four radial artery grafts showed diffuse narrowing. The patency rate of the intern al thoracic artery grafts was 100% with an average internal diameter o f 2.25 mm. Three of 62 grafts demonstrated diffuse narrowing, Two of 2 4 (7.7%) saphenous vein grafts were occluded; the average internal dia meter was 3.23 mm. The internal thoracic artery, the radial artery, an d saphenous vein grafts were, respectively, 7.5%, 19.5%, and 53.3% lar ger than the anastomosed native coronary arteries, Graft-dependent how was found in 81.1% of the radial artery grafts. Conclusion: The resul ts of this study demonstrate that the short-term patency rate of radia l artery grafts is excellent.
