[A comparative analysis of long-term outcomes of femoropoplietal autovenous bypass <<in situ>> grafting and the reversed vein].

Presented herein is a comparative analysis of the remote results obtained ofter a total of 215 operations of femoropoplietal autovenous bypass grafting performed by a reversed vein (n=105) and <<in situ>> technique (n=110). The patients from the both groups matched well by all criteria of the comparative analysis. Over a 5-year period, the cumulative patency rate of the <<in situ>> grafts amounted to 56.4%, and that by the reversed autovein equalled 47.6 %. The preservation rate in the both groups during the same time period amounted to 77.3 % and 67.7 %, respectively. The main factor exerting a statistically reliable influence on the patency of the femoropoplietal grafts was found to be the level of the establishment of the distal anastomosis. When the distal anastomosis was established, above the knee-joint fissure, no statistically significant differences in the patency of the grafts performed by of the reversed autovein and those carried out according to the <<in situ>> technique were revealed. Placing the distal anastomosis below the knee-joint fissure appeared to offer apparent advantages of autovenous grafting performed according to the <<in situ>> technique.
