title: Saphenous vein coronary bypass graft revisited.
abstract: To establish a benchmark for the clinical efficacy of PTCA and the IMA graft in our institution, the data from 79 patients who underwent isolated SVBG to the LAD between July, 1971, and December, 1984, were analyzed. Follow-up averaged 96.16 months/patient. Actuarial freedom from reoperation was 100% at 12 months, 95% at 60 months, and 89.4% at 120 months. Actuarial freedom from cardiac death was 100% at 12 months, 94% at 60 months, and 87% at 120 months. Actuarial freedom from an LAD graft failure myocardial event was 100% at 12 month, 94% at 60 months, and 77% at 120 months. Our SVBG failure rate did increase from 1.2%/year during the first 5 years to 3.4%/year during the second 5 years. We are presently selectively employing IMA grafts to the LAD. Our results with the SVBG and the palliative nature of all coronary artery bypass graft procedures remove the imperative to always use the IMA. Individual patient considerations such as age, clinical stability, IMA flow, and the residual anatomy for the potential reoperation are important considerations.
