THE CHOICE OF GRAFT MATERIAL IN TREATMENT OF AORTIC-ANEURYSM - FIRST RESULTS OF A PROSPECTIVE RANDOMIZED TRIAL

A prospective, randomized trial was performed to compare 40 patients w ith aortic aneurysms which mere treated by implantation of dacron or P TFE prostheses. Follow up was done according to a defined protocol for 3 to 34 months postoperatively. There was observed neither graft fail ure, vascular occlusion, perigraft-reaction nor infection in any case. In one patient a periprosthetic haematoma occurred. During postoperat ive follow up in each group one patient died. There mere no significan t differences in dilation of the material in both groups. Dacron prost heses dilated to 28,2%, PTFE to 30,5%. In both groups the graft limb d ilated more in comparison to the tube.
