Catheter obstruction is a major cause of dialysate flow problems in peritoneal dialysis (PD). It will lead to PD technique failure, when its conservative management such as vigorous instillation of dialysate occasionally fails to salvage the catheter potency. In this report, we present two cases of catheter obstruction caused by intraluminal clots of PD catheter. The clots, which could not be removed by the conservative management, were removed by a new technique using an angiographic guidewire. The technique could be an option to resolve PD catheter obstruction.
