Abstract: | BACKGROUND: The transdiaphragmatic approach is useful for reoperative coronary artery bypass grafting involving the right coronary artery because it does not require median sternotomy or cardiopulmonary bypass. METHODS: Twenty-one patients underwent coronary artery bypass surgery by the transdiaphragmatic approach. The ratio of first operations to reoperations was 7:14. The cause of reoperation was occlusion of a saphenous vein graft in 4 patients, right gastroepiploic artery graft failure in 3 patients, and a new sclerotic lesion in the right coronary artery in 7 patients. When the radial artery or saphenous vein was used, grafting extended from the origin of the gastroduodenal artery to the right coronary artery. RESULTS: None of the patients died during surgery. The sites of anastomoses were as follows: right coronary artery in 11 patients, right posterior descending artery in 9 patients, and the atrioventricular node artery in 1 patient. The following types of grafts were used: right gastroepiploic artery in 17 patients, saphenous vein in 2 patients, and radial artery in 2 patients. CONCLUSIONS: When reoperative coronary surgery involving the right coronary artery is necessary, the transdiaphragmatic technique is effective because it does not damage patent grafts placed during the primary operation. |
