External velour dacron grafts in renal artery reconstruction.
Aortorenal interposition grafts were performed in dogs using a new external velour knitted Dacron graft. Encapsulation and endothelialization of these grafts occurs as early as two weeks postoperatively. Complete healing is seen by six weeks, and the cellular lining of these grafts appears to be continuous with, and histologically similar to, the endothelium of contiguous arteries. The healed nonthrombogenic characteristics of this graft material represents a considerable improvement over graft materials of conventional design.
