Chronic dialysis in case of patients with extreme renal insufficiency frequently leads to loss of vascular access for hemodialysis. The only alternative for such patients is a transplantation of a kidney. The time of expectation may extend because of many reasons and a patient requires permanent and systematic dialysis. Then there is no option of maintaining a permanent access to dialysis but to artery-arterial by-pass with the usage of vascular prosthesis as an access to dialysis. Recent researches recommend prostheses covered with heparin. Such prosthesis are less of thrombosis and they curb processes connected to the height of the number of cells. At the same time they retain their patency for longer, especially in region of anastomosis. It permits to lengthen time of dialysis and also time of expectation for a kidney transplant. Our experiences are confirmed by other authors' observations and they also prove usefulness of heparin bonded prosthesis Propaten for producing artery-arterial by-pass as the only alternative of treating patients with chronic renal insufficiency in cases of whom all possibilities of vascular access for hemodialysis were depleted.
