Summary
Mechanical issues frequently cause catheter failure in continuous ambulatory peritoneal dialysis (CAPD). Catheter displacement is the leading cause of removal, particularly with straight catheters.
Area of Science:
- Nephrology
- Medical Devices
- Surgical Procedures
Background:
- Mechanical complications are a primary cause of catheter failure in continuous ambulatory peritoneal dialysis (CAPD).
- Understanding these mechanical issues is crucial for improving patient outcomes and device longevity.
Purpose of the Study:
- To analyze the types and causes of mechanical problems encountered with peritoneal dialysis catheters.
- To identify the most frequent reasons for catheter removal due to mechanical complications.
Main Methods:
- A retrospective review of 105 peritoneal dialysis catheters implanted over 11 years.
- Classification of 137 mechanical problems based on their etiology, including insertion, dialysate presence, malfunction, abdominal events, and accidents.
Main Results:
- Mechanical complications led to the removal of 19 out of 105 catheters (21.8%).
- Nine patients required a permanent switch to hemodialysis due to these mechanical issues.
- Catheter accidents were the most frequent complications, but often did not necessitate removal.
Conclusions:
- Catheter displacement was the most common reason for catheter removal (31.5%).
- Straight catheters experienced displacement more frequently than Swan Neck catheters.
