Abstract:
Between May in 1988 and October in 1990, simultaneous coronary artery bypass grafting (CABG) and valve surgery was performed in 14 patients. Nine patients received arterial graft conduit for CABG (AG group) and only saphenous vein graft (SVG) was used in 5 patients (SVG group). In AG group, mean age was 63.3 years and the number of distal anastomosis was 2.2/patient. In valve operation, valve replacement was performed in 5 and valve plasty was in 4, and the mean aortic cross clamping time was 116min. As AG, internal thoracic artery (ITA) was used in 8 and right gastroepiploic artery (RGEA) was in 4. Among them concomitant use of ITA and RGEA was in 3, and the use of SVG was in 5. In two patients, the AG pedicle did not reach to either left anterior descending or obtuse marginal artery and the SVG was used as a graft conduit. Between AG group and SVG group, there were no significances in the age and aortic cross clamping time. However, postoperative use of cathecholamin was in three (33%) in AG group and three (60%) in SVG group and there were significant differences between them. In AG group, there were no operative deaths and the late NYHA improved to class I in 4 and class II in 5. In simultaneous CABG with AG and valve surgery, the improvement of symptom was good and stable operative result was obtained, however, the length of the pedicled graft should be carefully considered for coronary anastomosis.
