ABSTRACT
Blood flows, pressure gradients and venous oxygen saturations performed at the time of insertion and reoperation during a clinical evaluation of 38 bovine grafts during the years 1962 to 1971 demonstrated that: (1) grafts with flows greater than 50 ml/min are capable of remaining patent for many months; (2) blood flow is a better indication of an adequate vascular bed than the interpretation of arteriograms; (3) venous oxygen saturations reflect both poor perfusion and improvement in perfusion of ischemic areas only if the sampling is done from a vein which primarily drains the ischemic area. Follow-up examination at intervals of six to 12 months during a nine-year period combined with 48 reoperations made it possible to show that practically all occlusions were due to progression of arteriosclerotic occlusive disease.
