[Use of the right gastroepiploic artery as a coronary bypass graft. Indications, technique and early results].
435 isolated coronary artery procedures have been performed between January and December 1989 at the HerzZentrum Hirslanden. In 93% of the cases, one or two internal mammary arteries (IMA) and in 7%, saphenous vein grafts only were used as a bypass conduit. In 12 patients, the right gastroepiploic artery (RGE) was used as a free (3) or pedicled (9) graft to the posterior surface of the heart. This group of 12 patients was analyzed in a retrospective study. Postoperative complications in this group included one myocardial infarction and reexploration for intraabdominal bleeding in the same patient. All patients were discharged from hospital after an average of 9.7 days. After a mean follow-up time of 5 months, all patients are in NYHA-functional class I without antiischemic drugs. Postoperative angiography in 7 patients (mean postoperative interval 4 months) showed all 13 IMA-grafts and 5 RGE-grafts patent, 1 RGE-conduit is occluded, 1 RGE-graft could not been assessed for technical reasons. The RGE is an viable additional arterial bypass conduit and an alternative to other grafts. Indications for use of the RGE are lack of sufficient other conduits, calcified ascending aorta, coronary reoperation after vein graft failure and probably young patients with severe hyperlipidemia.
