[Radial artery for coronary artery bypass graft].

Abstract

Early postoperative results were studied in 50 cases of coronary artery bypass graft (CABG) using a radial artery (RA). The patients ranged in age from 37 to 81 years, with the mean age of 61 years. Of them, 49 were male. An average of RA was 17.6 cm at completion of detachment and 15.6 cm when the graft was cut for use. The internal diameter before anastomosis an average of 3.7 mm on the proximal side and an average of 2.8 mm on the distal side. RA was anastomosed with ascending aorta in 47 cases, with the left internal thoracic artery in 2 cases and with the right internal thoracic artery in one case on the proximal side. RA was anastomosed with the left anterior descending branch area in 6 cases, with the left circumflex branch area in 40 cases and with the right coronary artery area in 4 cases on the distal side. There was no case of operative death, but one patient died while in hospital. The cumulative patency rate of the RA grafts was 95% (n = 40). Early postoperative results of the RA graft were satisfactory, therefore the RA graft were satisfactory, therefore the RA graft was an excellent alternative conduit for myocardial revascularization.
