title: Aortobifemoral grafting: factors influencing long-term results.
abstract: We present the results and respective determinant factors of 283 consecutive aortobifemoral bypasses. This prospective study included 283 patients with aortoiliac atherosclerotic occlusive disease treated by aortobifemoral reconstructions. Polytetrafluoroethylene (PTFE) grafts were used in 136 patients and Dacron grafts in 147 patients. The 30-day mortality rate was 11 patients (3.9%). Perioperative (< 30 days) graft failure occurred in 6 patients (2.1%), whereas in 14 (5.25%) patients, it occurred during the follow-up period. There were 3 (1.05%) distal anastomotic pseudoaneurysms and 5 (1.7%) graft infections, with no statistical difference between the two types of grafts. The type of prosthesis did not influence cumulative graft patency. The end-to-end configuration of proximal anastomosis and a simultaneously performed femoropopliteal bypass significantly increased the graft patency (p < .05). The associated occlusion of the superficial femoral and popliteal arteries decreased the cumulative graft patency in comparison with that of the patients without artery disease (p < .05). Our results showed that in the aortobifemoral position, there was no significant difference in the patency, anastomotic pseudoaneurysms, and graft infection between PTFE and Dacron grafts. However, the PTFE grafts had a significantly higher rate (p < .05) of distal anastomotic stenosis, which was mostly caused by neointimal hyperplasia.
