After 3 years a preliminary evaluation of a prospective randomized study between PTFE-Y- and Dacron-Y-grafts in regard to function rate, complication and quality of material was performed. Both, function rate and complications showed no significant differences between both groups. In all patients with graft limb occlusion (1 early and 4 later occlusions) the function was gained by successful thrombectomy. Today Dacron-Y-prosthesis is available as collagen coated dacron double veloure graft, so presenting the same most important advantage PTFE prosthesis did (no preclotting). In cause of those above mentioned material characteristics both grafts seem to be equal in quality.
