Experimental evaluation of polymerized Dacron grafts in the iliac position of pigs.
Three differently polymerized Dacron grafts were compared to ordinary Dacron grafts and polytetrafluoroethylene grafts in the iliac artery of pigs. The grafts were inserted end-to-side and left for 40 days. Explantation was performed after glutaraldehyde pressure fixation. Gross morphology, light microscopy, and scanning electron microscopy were used to examine the specimens. We concluded that the polymerized grafts behaved similarly to polytetrafluoroethylene grafts and had a very limited foreign body reaction. Endothelial-like cells covered most of the graft surface.
