RESUMO
The paper presents the results of 80 femoro-popliteal bypasses above popliteal fossa for patients with lower limb atherosclerotic lesions that were fulfilled with the use of polytetrafluoroethylene (PTFE) graft in the Department of Vascular Surgery, AV Vishnevsky Institute of Surgery, from February 1992 till December 2005. 50% of patients had lower limb ischemia grade IIb, 13.7% - grade III and 36.3% - grade IV. Distal circulation was good in 41.2%, satisfactory - in 48.5% and unsatisfactory - in 10.3% of patients. The technique of surgical reconstruction was conventional. In 50% of cases the diameter of PTFE grafts was 8 mm, in another 50% - 6 mm. A statistically significant difference in bypass patency was revealed between prostheses with different diameter in late postoperative period. For the 8-mm grafts the patency rate was 93%, 64% and 51% in 12, 30 and 60 months, respectively, while for the 6-mm grafts the same rate was 62%, 44% and 31%, respectively (p=0.004).

Presented herein are the outcomes of a total of 80 operations of femoropopliteal grafting above the knee-joint fissure, carried out using a vascular prosthesis made of polytetrafluoroethylene (PTFE) in patients diagnosed with atherosclerotic lesions of the arteries of the lower extremities over the period between February 1995 and December 2005 at the Department of Vascular Surgery of the A. V. Vishnevsky Institute of Surgery of the Russian Academy of Medical Sciences. Fifty percent of the patients were operated on for grade II B ischemia, while 13.7% of the patients suffered from grade III ischaemia of the lower limb, and 29 (36.3%) subjects were found to have grade IV ischaemia. The condition of the distal bed was considered <
