Objective: To analyze the results of extensive reconstruction of the left anterior descending coronary artery (LAD) by an autologous vein patch, with or without endarterectomy (EA), associated with left internal mammary artery grafting onto the patch. Methods: Between January 1994 and April 2001, among 5871 myocardial revascularizations, 83 patients (1.4%), 77 male (93%), with a mean age±SD of 64±8 years (range 44–84) underwent the above mentioned procedure. Seventy-three of them (88%) were in Canadian Cardiovascular Society (CCS) Class III or IV, and 78 (94%) had a three-vessel disease. Mean preoperative ejection fraction was 58±12%. Risk factors included hypertension (63%), family history (51%), hyperlipidemia (41%), smoking (38%), diabetes (19%). Mean number of anastomoses/patient was 3±0.6. Mean length of vein patch was 2.8±0.9 cm (range 2–6 cm). A total of 16% of the …
