Different analyses (SEM (scanning electron microscopy), light microscopy, nuclear medical investigations) must be added to short-term carotid artery test, in order to allow a real prediction of the behavior of suitable vascular grafts in the in-vivo long-term test. Comparing 60 experimental implantations (5 different prosthetic materials) in carotid artery position with more than 150 vascular grafts in long-term in-vivo tests led to a new point system to appraise the various parameters of the short-term method numerically. An initial thrombogenicity of the prosthetic wall and the formation of an intramural thrombogenic matrix were found to be prerequisites for the ingrowth of connective tissue, transprosthetic microvascularization, and multifocal spontaneous endothelial lining.
