[Heterologous and alloplastic grafts for haemodyalisis (author's transl)]

In cases of the malfunction of av-fistulae for haemodialyses a kind of prosthetic graft has to be used. Since 1973 alloplastic protheses (Sparks-Mandril) have been used in 7 patients, since 1976 heterologous (Solko-graft-calf-carotis) ones in 12 patients. In an average follow-up period of 18 months the heterologous prostheses proved to be more suitable because of longer patency-rates, simpler handling during surgery and earlier use for dialyses. As a major late complication only one case of an aneurysmatic enlargement was observed in one of the heterologous protheses. Long-term results have still to be waited for.
