Abstract 2125: Twenty Year Experience with the Gastroepiploic Artery Graft for CABG in 1352 Patients
The right gastroepiploic artery (GEA) has been used for coronary artery bypass grafting (CABG) in 1352 patients during 20-years period. There were 1092 males and 260 females with a mean age of 63 years. Single-, double-, and triple-vessel and left main disease were noted in 9, 213, 899 and 231 patients, respectively. Internal thoracic artery (ITA) and radial artery grafts were concomitantly used in 1312(97%) and 128(8%) patients, respectively. The mean number of distal anastomoses was 3.1, and 2.4 coronary arteries were bypassed with arterial grafts. The sites of GEA grafting were 70 anterior descending, 7 diagonal, 268 circumflex, and 1089 right coronary arteries. Operative mortality was 1.26% (17patients). Postoperative angiography revealed 95% (952/1002) early (within 1year), 87% (152/174) midterm (1–5years) and 85% (51/60) late (5–15 years) patency rates of the GEA grafts. Risk factors for late occlusion were anastomotic stenosis and less critical stenosis in the grafted coronary artery. A skeltonized GEA graft was preferentially used in the last 4 years in 203 patients. Postoperative angiography was perfomed in 172 skeltonized GEA grafts with 233 distal anastomoses, and the patency rate was 97%(7 occluded) within 1 postoperative year. In conclusion, GEA is a safe and effective arterial conduit for CABG.
