Right gastroepiploic artery graft: Long-term clinical follow-up in 271 patients - Experience of a single center

BACKGROUND AND AIM: We present our experience in the use of right gastroepiploic artery (rGEA). Long-term clinical results are reported. METHODS: From April 1994 to June 2005, 271 patients (257 males, mean age 56.2 +/- 7.1) underwent coronary artery bypass grafting with the use of rGEA. Preoperative, perioperative, and postoperative data were retrospectively collected and clinical results and survival were examined. The end points of follow-up were death and recurrence of cardiac events such as angina and myocardial infarction (MI). The mean follow-up was 8.2 +/- 2.9 years. RESULTS: Left ventricular ejection fraction ranged from 0.20 to 0.68 (mean 0.55 +/- 0.7). The mean cardiopulmonary bypass time was 96.8 +/- 15.8 minutes and the mean cross-clamping time was 69.7 +/- 14.2 minutes. The mean number of distal anastomosis was 3.3 +/- 0.7 (range 2 to 5). Early mortality was 2.6% and postoperative MI occurred in three patients. There were 21 (7.9%) late deaths and three of them (1.2%) were cardiac related. Actuarial 10-year-survival of all deaths, including in-hospital death, was 70.8%+/- 9.9%. No abdominal complications occurred during or after rGEA harvesting. Seven patients have been suffering of recurrence of angina. Angiography was performed only on those patients with recurrent angina. CONCLUSION: The rGEA can be considered as a valid arterial conduit, relatively easy to harvest, safe to use with low perioperative risks, and good mid- and long-term results. The low early and late rate mortality and the satisfactory clinical results are good reasons for using routinely this conduit in selected patients.
