Peripherally inserted central catheters: resistance to removal: a rare complication
Summary
Peripherally inserted central catheters (PICCs) can resist removal due to venospasm, confirmed by ultrasound. Gentle traction and warm soaks typically resolve this, though one case required extended intervention.
Area of Science:
- Vascular Access Devices
- Ultrasound Imaging
- Interventional Procedures
Background:
- Peripherally inserted central catheters (PICCs) are crucial for long-term venous access.
- Catheter removal difficulties, occurring in 0.965% of cases, pose clinical challenges.
- Potential causes include infection, fibrin sheath formation, and endothelial thrombosis.
Observation:
- This study identifies venospasm, visualized via ultrasound, as a primary cause of resistant PICC removal.
- Ultrasound confirmation of venospasm provides objective evidence for difficult removals.
Findings:
- A treatment protocol involving gentle traction, warm soaks, and tourniquet application achieved successful removal in most cases within an hour.
- One catheter remained resistant for six days despite adherence to the protocol.
- Management strategies for potential catheter embolization during removal are also discussed.
Implications:
- Recognizing and treating venospasm can improve the safety and efficiency of PICC removal.
- Ultrasound guidance may aid in diagnosing the cause of difficult catheter removals.
- Standardized protocols for resistant PICC removal can minimize patient discomfort and procedural risks.
