Abstract

Neointima formation of fabric vasucular prosthesis is observed in general at only the areas near anastomotic sites in clinical cases in a long term periods.
Neointima cell lining with elastic laminae and smooth muscle cells of an adipose tissue fragmented vascular prosthesis was seen at 4 months after surgery at every part of the luminal surface in clinical case. And the removed specimen 10 months after implantation showed neointima formation composed of circular elastic laminae and smooth muscle cells.
These finding have never been reported for any other fabric vascular prostheses previously in clinical setting.
