[Diagnostic and therapeutic problem of infected arteriovenous fistula for hemodialysis-case report].

On the case of 48 old patient with chronic renal failure, treated with repeated hemodialyses, we described diagnostic and therapeutic problems of infected arterio-venous fistula of severe clinical course and rare epidemiology (Staphylococcus warneri). Special attention was paid to the difficulties in the confirmation of bacterial etiology of this infection as well as practical usefulness of ultrasonography in the monitoring of clinical course and therapy of infected arteriovenous fistula.
