The authors analysed the outcomes of 476 reconstructions performed on the aortofemoral segment for Leriche's syndrome using polytetrafluoroethylene grafts «ECOFLON» within the time frame from 1997 to 2007. The in hospital mortality rate amounted to 2.7%, thrombosis rate to 0.46%, and amputation rate to 0.69%. The remote results were assessed at follow-up terms varying from 6 to 108 months, with the mean follow-up time thus amounting to 34.6±1.3 months. Secondary graft patency by the first postoperative year amounted to 98.0±0.62%, by 5 years to 92.5±1.9%, and by 9 years to 91.4±1.9%, with primary graft patency being 97.3±0.23%, 84.9±2.9%, and 82.9±3.5%, respectively. The limb salvage rate amounted to 97±0.6% after 1 year, equalling 91.2±2.2% after 5 years, and 80.9±5.2% after 9 years. Infection of prosthetic grafts occurred in 1.04% of cases (0.42% in the short-, and 1.05 % in the long-term periods). Pseudoaneurysms of distal anastomoses were observed in 0.34% of cases. Analysing two time intervals (i. e., 1997-2002 and 2003-2007) showed a statistically significant betterment of the patency rates (with primary graft patency having increased by 5.3% and secondary graft patency by 5.8%, P<0.01), thus apparently suggesting improved quality of explants. It was concluded that polytetrafluoroethylene grafts «ECOFLON» comply with the present-day standards of quality.
