    Abstract:
    Internal thoracic artery (ITA) grafts for coronary artery bypass grafting (CABG) are superior to SVG in the long-term patency and survival. In spite of our effort to utilize ITA whenever possible, we still have some cases which have to receive only vein grafts. Among the consecutive 201 patients undergoing CABG in the past three years, 32 patients (16%) received only vein grafts. We compared these patients (SVG group) with those who received ITA grafts (ITA group). The SVG group consisted of all emergency cases and many cases with single and double vessel disease. In the SVG group, perioperative use of IABP was more frequent and operative mortality was higher, although the number of grafts was fewer (2.66 vs 3.61) and aortic cross clamping time was shorter in this group. Main reasons for selecting only vein grafts were emergency surgery, inadvertent injury of ITA, inadequate ITA free flow etc. Technical refinement in the preparation of ITA is important to make possible wider application of arterial grafts for CABG.
