Abstract

BACKGROUND: It has been known that internal thoracic artery grafting has a better patency rate compare to other graft conduits in coronary revascularization. Better patency rates can be expected in more coronary arteries with the use of bilateral internal thoracic artery. However, there were some debates on the complications after the use of bilateral internal thoracic artery. The purpose of our study was to reveal the results of bilateral internal thoracic artery. MATERIAL AND METHOD: The 26 coronary artery bypass operations with bilateral internal thoracic artery were performed from July 2001 to May 2002. We compared the results of 8 diabetic patients to those of 18 non-diabetic patients. We compared the results of BITA (bilateral internal thoracic artery) group to those of SITA (single internal thoracic artery) group that were 20 patients and performed during same period. RESULT: There was no mortality. There was one wound complication in the diabetic group and one in the non-diabetic group. There were no significant differences in operation time, duration of mechanical ventilation, amount of bleeding, infusing duration of cardiotonics, and complication between two groups. There were no significant differences in results between the BITA group and the SITA group.
CONCLUSION
There were no significant differences in early results between the BITA group and the SITA group, and there were no significant differences in results between the diabetic group and the non-diabetic group. We think coronary artery bypass grafting with the use of bilateral internal thoracic artery is considered in diabetic patients.
