[Early postoperative results of coronary revascularization with the radial artery: an analytical study of vascular diameter ratio of the graft and the coronary artery].
Between October 1996 and June 1988, radial artery grafts were used in 49 patients undergoing myocardial revascularization. There were three hospital deaths, none of them due to the use of radial artery. In 32 patients studied early, 33 of 34 radial artery grafts were patent (patency 97%), and 30 of 32 internal thoracic artery grafts (94%), 32 of 35 saphenous vein grafts (90%), 3 of 3 gastroepiploic artery grafts (100%) were patent respectively. The mean diameter ratio of graft and recipient coronary artery was 1.03 +/- 0.17 in radial artery, 0.92 +/- 0.16 in internal thoracic artery and 1.67 +/- 0.55 in saphenous vein graft. Our result suggest that the radial artery is an excellent conduit for myocardial revascularization, although a longer follow-up is mandatory.
