Abstract
The technique survival of peritoneal dialysis (PD) is limited, and transitions to haemodialysis (HD) are often unpredictable, due to events such as peritonitis or catheter malfunction. As such, there is a high risk of central venous catheter (CVC) use amongst patients who transition from PD to HD. Formation of a ‘back-up’ arteriovenous fistula (AVF) at the commencement of PD may reduce the risk of later CVC use, but risks exposing patients to complications of an AVF that may never be needed. Studies in the 1990s concluded that few AVFs created as back-ups were ever used, and recommended against routine formation of back-up AVFs.
