The histologic finding of auto-alloplastic graft transplantation for vessels, capsulated with peritoneum, was stadied in the long period. Poor vascular plex us of nutrition and no muscular cell were found in the adventia and media layers, which were different to the normal abdominal aorta Interestirgly, no fibrotic hyperplasia or cellular infiltration was presented, meanwhile the thickness of the wall resembled to normal vessel in the structure.
In the central part of the graft, endothelial cells were exfoliated scatteredly but no thrombotic formation overthere. On the centrary, endothelial regimentation repeated and fibrin mat of the course of endothelial formation was presented. Multiple holes or depresion was found in these parts, which may be related with nutrition of tissue.
1) The auto-alloplastic graft is mesodermal, same as vessels. Therefore the structure was presented stabely.
2) Though the long stable of this graft was presented, exfoliation of endotheluim and regimentation occurred.
3) Nutrition was important in the course of endothelial cell formation from fibrin mat.
4) Hyperplasia of collagen fiber in the anastomasis got less if getting stable.
