Background:
To evaluate the safety and effectiveness of a stepwise interventional strategy for the removal of adherent totally implanted central venous access port catheters, consisting of a guidewire support, antegrade coaxial separation, and retrograde coaxial separation with increasing technical complexity.
Methods:
This study has a retrospective design. Thirty-two patients who had failed routine removal of the port catheter and were then transferred to interventional radiology between November 2017 and December 2023 were reviewed. The technical success and complication rates were recorded.
Results:
All adherent catheters were successfully removed without catheter fragmentation, using guidewire support (n = 21), antegrade coaxial separation (n = 5), and retrograde coaxial separation (n = 6). The technical success rate was 100%, and no complications occurred.
Conclusions:
The proposed stepwise interventional strategy successfully removed adherent port catheters, with good safety and high effectiveness. It appeared to reduce the incidence of catheter fracture during the removal of adherent totally implantable central venous access port catheters.
