The authors are presenting late results and respective determinant factors on basis of 283 consecutive aorto-bifemoral bypasses. The bifurcated PTFE graft was used in 136, while the knitted Dacron graft in 147 cases. There were 25 (8.8%) female and 258 (91.2%) male patients, average age of 56. 88 years (32-82). The mean follow up period was 3.6 years (one to 9.5 years). The intrahospital mortality rate was 11 (3.9%). Immediate graft patency was 96.4% for PTFE, and 99.4% for Dacron graft, while late patency rate was 94.9% and 96.6%, without statistically significant difference between two types of grafts (p>0.05). The location of distal anastomosis at the deep femoral artery and simultaneously performed femoro-popliteal bypass significantly increased graft patency (p<0.05), while occlusion of the superficial femoral artery decreased graft patency, however not significantly (p>0.05). The configuration of the proximal anastomosis did not influenced graft patency. There were 6 (2.1%) early and 14 (5.2%) late graft occlusions, 3 (1.05%) distal anastomotic pseudoaneurysms and 5 (1.7%) graft infection, also with no statistically difference between two types of grafts. The distal anastomotic stenosis caused by neointimal hyperplasia was statistically grater in patients with PTFE grafts.
