Late angiographic result of using the right gastroepiploic artery as a graft.
OBJECTIVE
The angiographic patency of the right gastroepiploic artery graft used for coronary artery bypass grafting was studied during the late (5-10 years) postoperative period.


METHODS
Among 936 patients undergoing a gastroepiploic artery graft for coronary artery bypass grafting between 1986 and 1999, postoperative angiographic restudy was conducted on 685 patients within 1 year (mean, 2.2 months), on 102 patients between 1 and 5 years (mean, 2.3 years), and on 52 patients between 5 and 10 years (mean, 7.8 years).


RESULTS
The patency rate of the gastroepiploic artery graft was 94%, 88%, and 83% in each restudy group. The cumulative patency rate estimated by the Kaplan-Meier method was 96.6% at 1 month, 91.4% at 1 year, 80.5% at 5 years, and 62.5% at 10 years. Causes of late occlusion were primary anastomotic stenosis and anastomosis to a less critically stenosed coronary artery. Once the gastroepiploic artery was perfectly anastomosed to the coronary artery, which has tight stenosis and good runoff, late patency was good, and new stenosis in both the gastroepiploic artery trunk and the anastomotic site was uncommon.


CONCLUSIONS
The gastroepiploic artery graft can be used effectively for coronary artery bypass for the long term with proper target selection.
