[Surgical tactics in the treatment of postoperative thrombosis of reconstructed arteries].

The trial included 894 patients in postoperative period with thrombosis of reconstructed arteries, who had undergone since 1975 1100 repeated reconstructive operations. Vast experience of reoperations on the vessels allowed to summarize various types of reoperations, to systematize them and to propose new classification. Surgical policy was determined by the causes of acute thrombosis and the time of its duration. Evaluation of the results of repeated reconstructions has revealed, that patency of the by-passes in the aorto-femoro-popliteal area in long-term postoperative period is significantly lower than after surgery on renal arteries and brachiocephalic branches. A significant difference in patency in femoro-popliteal and tibial segments is revealed since the 2nd year, in aorto-femoral-since the 4th year after surgery. The function of the shunts in patients with nonspecific aortic arteritis in follow up period is significantly lower than in patients with atherosclerosis beginning from the 2nd year of follow-up. The repeated reconstructive operations for early and late thromboses in femoro-tibial segment are almost ineffective. Up to year 3 after the repeated operation patients with stage II of ischemia after Fontaine make up 19%, and up to year 5--only 9%. In the rest of the patients chronic critical ischemia with the loss of the limb is develops.
