New-Generation Glutaraldehyde-Tanned Mandril-Grown Vascular Grafts

Abstract

In order to improve the capability of withstanding mechanical trauma dur ing surgical manipulations, a new generation of tanned ovine collagen vascular grafts with a thicker inner tissue cover has been developed. In spite of such structural refinements, long-term performance of the new grafts, implanted in the inferior vena cava of pigs, was not superior to that of the former grafts.
