摘要: Summary Postoperative coronary bypass flow was evaluated in two groups of randomly selected patients with grafts to the left anterior descending artery (LAD). Saphenous vein were placed 27 and internal mammary 25 patients. studies performed both roentgenden-sitometric methods based on transit time radiopaque media along graft plus mean diameter. There no significant difference between for age, duration symptoms, or frequency hypertension, diabetes mellitus, prior myocardial infarction, cardiomegaly. Intraoperative flows 75±27 77±24 ml. per minute saphenous group (SVG) (IMAG), respectively. heart rate aortic pressure at roentgendensitometric study. The diameters 3.0±0.5 1.9±0.3 mm.
