Abstract
Summary
The inner lining of autogenous vein patch grafts placed into small canine arteries by microsurgical techniques was studied. The grafts placed in 22 femoral arteries of 13 dogs were kept in place from 2 days to 76 weeks. Aortography disclosed patency of all the arteries grafted with no or slight dilatation at the site of operation.
En face silver preparations disclosed that the intimal surfaces of the grafts were covered with endothelium after the 4th day. Endothelial cells were demonstrated in pellicle preparations. The patch contributed its own substance, particularly elastic fibers, to the repair of the arterial wall.
