Abstract
A novel, microporous, hydrophilic polyether urethane‐urea (PEUU) vascular graft was compared with expanded PTFE in the canine carotid artery. At implantation times ranging from 4 h to 6 months, all the PEUU grafts were found to be occluded while of the PTFE grafts, only those implanted for 1 week and 6 months were blocked. Histopathological analysis of the explanted grafts and their capsules revealed an on‐going inflammatory reaction at the anastomotic sites of the PEUU grafts.This publication has 6 references indexed in Scilit:
