[Factors influencing the remote patency of distal shunts in patients with atherosclerosis of lower extremity arteries].

Under study was the prognostic value of local risk factors of the development of late reocclusion of distal shunts in 149 patients with critical ischemia of lower extremities. It was found that the greatest influence on the remote patency of transplants is exerted by the state of the arterial wall in the area of the distal and in less degree of the proximal anastomoses. In a less degree the duration of functioning of the shunt depended on its length, position in soft tissues, transplant material and the level of the proximal anastomosis. The distal anastomosis level, the history of the simultaneous or previously made aorto-femoral shunt, geometry of the proximal and distal anastomoses did not have any reliable influence on the distal shunt patency.
