Abstract
An alternative way to revascularize coronary vessels is described, using arterial conduits without extracorporeal circulation. The heart is exposed via a small thoracotomy over the fifth left intercostal space. A thoracoscope is introduced into the thorax, to assist in the harvesting of the left internal mammary artery (LIMA). In selected patients with two or three vessel disease, the same procedure can be achieved on the right side, harvesting the right internal mammary artery to revascularize the right coronary artery. The gastroepiploic artery can be easily reached and used to revascularize the posterior descending artery, through a mini-subxiphoid median laparotomy. This technique was used to revascularize 30 patients from April 1994 to June 1995. All received a LIMA graft to the left anterior descending artery, and two had a free radial artery graft from the LIMA, sequentially bypassing the diagonal and obtuse marginal branches. There was neither perioperative mortality nor morbidity myocardial infarction. Fifteen patients were restudied angiographically before discharge. Average hospital stay was 43 ± 11 hours.
