[The peculiarities of formation repetitive AV-fistula].

The issues concerning the formation of an arteriovenous fistula (AV-fistula) remain to be one of the most important in modern vascular surgery and nephrology. 193 surgically treated patients in the terminal stage of chronic renal insufficiency have been analyzed and examined. 136 operations and 57 repeated procedures of surgical correction of vascular access or formation of new access were performed. The conical vascular prosthesis (diameter 4-6 mm and 5-7 mm; length - 40 cm and 60) for appropriate hemodialysis is recommended. In case of failure of vascular access for hemodialysis PTFE vascular access grafts as the most suitable are recommended.
