[Place of the right gastro-epiploic artery in coronary revascularization by exclusive arterial grafts].
From March 1990 to July 1991, 35 patients underwent coronary artery bypass grafts using the right gastro-epiploic artery (GEA). Twenty-nine patients had exclusively arterial grafts using a combination of GEA and internal mammary artery (IMA) in situ. The selection criteria for this group of 29 patients included a life expectancy exceeding ten years to avoid the need for reoperation due to deterioration of the grafts. This group consisted of 27 men and two women under the age of 70 years (mean age: 58 years, range: 36 to 70), 11 patients (38%) were under the age of 50 years and 15 (52%) were under the age of 60 years. Cardiac status was relatively well preserved. The mean ejection fraction was 58% (range: 25-70%). Fourteen patients (48%) had had a preoperative myocardial infarction. Fifty-five p. cent were smokers, 41% suffered from HT and 31% had a dyslipidaemia. Six patients (20%) had respiratory failure, 6 others (20%) were severely overweight and 2 patients were diabetic. According to the NYHA classification, 14 patients (48%) were stage IV, 9 patients (31%) were stage III and 6 patients (20%) were stage II. The mean number of bypass grafts per patient was 2.8 and 8 sequential bypass grafts (27%) were performed. The GEA was used in 29 cases, the left IMA was used in 28 cases, the right IMA was used in 13 cases and the epigastric artery was used as a free graft in 3 cases. Associated lesions included a resected left ventricular aneurysm. No associated valve procedures were performed.(ABSTRACT TRUNCATED AT 250 WORDS)
