Insights
Peritoneal dialysis (PD) catheter obstruction by blood clots can be challenging. A novel technique using endoscopic retrograde cholangiopancreatography (ERCP) guidewire and targeted thrombolysis successfully preserved PD catheter function.
Area of Science:
- Nephrology
- Gastroenterology
- Medical Device Technology
Background:
- Peritoneal dialysis (PD) catheter malfunction, often due to intraluminal blood clots, frequently necessitates catheter removal and transfer to hemodialysis.
- Standard treatments include heparinized saline irrigation, thrombolytic agents, and mechanical methods like intraluminal brushing.
Observation:
- A case presented where an intraluminal blood clot in a PD catheter persisted despite conventional thrombolytic and mechanical interventions.
- The coiled nature of the PD catheter complicated clot access and treatment.
Findings:
- A novel approach involved using an endoscopic retrograde cholangiopancreatography (ERCP) guidewire to reinforce the PD catheter and puncture the clot.
- Targeted thrombolysis was administered directly to the clot using a Swing Tip cannula, successfully dissolving the obstruction.
Implications:
- This case demonstrates a successful strategy for salvaging PD catheters with persistent intraluminal clots, potentially avoiding catheter removal and transition to hemodialysis.
- The described technique offers a viable alternative for managing complex PD catheter obstructions, preserving treatment continuity for patients.
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.
