Tanned Collagen Arterial Prosthesis of Bovine Carotid Origin in Man

Abstract
Enzymatically modified bovine arteries have been implanted as iliac and femoropopliteal arterial substitutes in man in 17 instances. There were 2 immediate failures, and 2 grafts closed at 2 1/2 and 7 months, respectively. Eight grafts were followed 1 year or longer, with one failure after 28 months.
