Fate of omental graft after revascularization of the heart.
Three patients who had had epicardiectomy, and internal mammary artery and omental grafts implanted as part of myocardial revascularization, recently underwent a second operation for coronary artery bypass grafting. All internal mammary artery implants were patent and appeared to revascularize the myocardium distal to the occluded segment of the coronary artery, as determined by angiography. Although adhesions were present at operation, there was no evidence of the free omental graft in two patients. The pedicled omental graft was present and viable in the remaining patient, but did not appear to have vascular communication with the epicardiectomized myocardium.
