Abstract

BACKGROUND
Increasing interest and use of arterial conduits is based on the better patency of left internal thoracic artery(LITA) than that of saphenous vein(SV) graft. We compared the early result of coronary artery bypass grafting(CABG) using LITA and radial artery(RA group) with CABG using LITA and SV only(SV group). MATERIAL AND METHOD: We compared the early operative results of 6 cases in RA group with 18 cases in SV group selected from 24 cases that had CABG between January 2006 and December 2006. We analyzed each group on the preoperative risk factors and operative results.
RESULTS
We can't find significant differences in clinical and hemodynamic characteristics before surgery. There were no statically significant difference between two groups in operative mortality and each morbidities(postoperative intraaortic balloon pump insertion, bleeding, stroke, perioperative myocardial infarction, wound dehiscence), respectively. However, the overall incidence of conventional CABG using cardiopulmonary bypass was higher in RA group compared to SV group(p=0.016). Accordingly, RA group had longer duration of ventilation time(p=0.004) and ICU stay(p=0.003) than SV group with statically significant difference between two groups in hospital stay. The graft patency on postoperative coronary angiography or computerized tomographic angiography at 7-14 days after operation in both group patients were 100%(includeing LITA, RA and SV).
CONCLUSION
We had early good operative results in RA group and SV group.
