Summary
Embedded central venous catheters can be challenging to remove. This case report details a successful retrograde endoluminal balloon dilation technique for retrieving an internalized dialysis catheter, offering a minimally invasive solution.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Nephrology
Background:
- Central venous catheters (CVCs) can become embedded due to vein wall adhesions.
- Embedded CVCs pose a significant retrieval challenge.
Purpose of the Study:
- To describe an effective, minimally invasive method for retrieving an embedded, internalized central venous dialysis catheter.
Main Methods:
- A retrograde endoluminal balloon dilation technique was employed.
- Seldinger technique facilitated access and guidewire passage.
- Catheter retrieval was achieved using a snare over a guidewire.
Main Results:
- Successful retrieval of an embedded internalised central venous dialysis catheter.
- Disruption of adhesions and freeing of the catheter were achieved via balloon dilation.
Conclusions:
- Retrograde endoluminal balloon dilation is an effective retrieval method for embedded internalised CVCs.
- This technique offers a minimally invasive approach for a rare complication.
