Abstract
The function of two types of Dacron vascular prostheses was evaluated in dogs using the abdominal aorta, inferior vena cava and iliac artery as host vessels. The transplants used were woven and knitted DeBakey prostheses and knitted Cooley prostheses. It is concluded that the function of a prosthesis with a diameter less than 5 mm is unsatisfactory. The same is true of a prosthesis implanted on the venous side, even in a large vein, such as the inferior caval vein, with a high flow. There is no significant difference between the function of DeBakey and Denton Cooley prostheses.
