[Surgical preparation planning of hemodialysis candidates]

An early beginning of chronic hemodialysis is postulated to prevent dangerous uremic complications. Subcutaneous arteriovenous fistulas or autologous saphenous vein grafts in cases where multiple attempts to create a sufficiently functioning arteriovenous fistula have failed turned out to be the best procedures to obtain a suitable access to the blood vessels. The problems arising on a total of 57 patients to get an adequate blood flow by the time of first hemodialysis are discussed.
