[Use of Soviet-made bioprostheses from the human umbilical vein in hemodialysis].

The work presents data on using a Soviet bioprosthesis made of a human umbilical cord at the firm "Sever" which was used as arteriovenous fistulas for hemodialysis. Operations were performed on 45 patients, 55 fistulas being formed. The maximum period of the follow-up was 3 years. An analysis of complications is given as well as of rational methods of their prevention and treatment. The bioprostheses are recommended for the formation of non-standard fistulas.
