Histological study of a polyamide arterial allograft (inside diameter: 1.5 mm) in rats

The histological results of the implantation of twenty aortal prosthesis (6-6 polyamide, internal diameter 1.5 mm) in rats are presented. The success rate is 77%. Biological tolerance is remarkably good. After the first month, the formation of a continuous endothelial layer is noted. At three months, the structure of the neo-membrane resembles that of the aortal.
