Abstract
Peritoneal dialysis (PD) catheter malfunction commonly leads to the removal of the catheter and eventually to a transfer to hemodialysis. The most common cause is intraluminal obstruction caused by blood and fibrin clots. Recommended interventions include irrigation of the catheter with heparinized saline; if this method fails, thrombolytic agents may be used. Mechanical methods such as intraluminal brushing are also utilized, typically after medical treatment fails. Here, we present a case of a patient who developed an intraluminal blood clot that persisted despite attempts with intraluminal thrombolytic drugs and intraluminal brushing. To salvage the catheter, targeted thrombolysis was performed using an endoscopic retrograde cholangiopancreatography (ERCP) guidewire to reinforce the coiled PD catheter and puncture the clots. Additionally, a Swing Tip cannula was employed for direct injection of the thrombolytic agent. These interventions successfully preserved the catheter, resolving the clot and ensuring continued functionality.
