Abstract
Prostheses of knitted, crimped dacron, some with and some without gelatin impregnation, were placed in the choracic aortas of 17 young pigs. The prostheses replaced excised segments of aortas, 4 to 6 cm long, and were left in place for 7 to 139 days. "En face" and pellicle silver preparations revealed complete endothelial covering of the surface of a prosthesis after 7 days.
