Influence of Porosity on the Viability of the Neointima

Abstract

The influence of porosity on the viability of the neointima was evaluated in 2 types of Dacron vascular prostheses with quite different porosities in dogs. The observed parietal thrombus formation in functioning prostheses and the dislodgement of the neointima in several of these might be attributed to the low porosity of the investigated prostheses, as compared to the recommended value. No pronounced difference in the histological picture was observed in the 2 types of prostheses, despite large differences in their mutual porosities.
