Learning objectives
To summarize the concurrent use of pigtail and loop snare catheters for retrieval of dislodged venous port catheters
Report our experience with 22 patients
Background
Central venous port catheters play an important role in the treatment of oncology patients and are commonly used for parenteral feeding and fluids and chemotherapy administration.
The most common complications are local bleeding and hematoma,
heart dysrhythmias,
arterial puncture,
hemothorax,
pneumothorax,
air embolism,
perforation of the central vein or cardiac chamber,
infection,
venous thrombosis,
catheter dysfunction and intravascular dislocation .
Port catheter dislodgement is seen in 0-4.1% of cases,
with up to 71% of them facing death or serious complications.
Dislodged catheter fragments can travel...
Findings and procedure details
This was a retrospective review of 22 patients referred to our department for intravascular retrieval of dislodged port catheters from June 2009 to July 2017.
All 22 patients had an underlying malignant disease and irrigation resistance was the most common symptom.
If there was no accessible free end for retrieval,
a pigtail catheter was used to relocate the dislodged port catheter so that an accessible free end is released.(Fig.2) At this point,
a snare loop catheter can easily snare the free end of the dislodged...
Conclusion
Port catheter dislodgement is seen in 0-4.1% of cases,
with up to 71% of them facing death or serious complications.
Dislodged catheter fragments can travel to the right heart or the pulmonary artery and might cause arrhythmias or pulmonary thromboembolism,
potentially threatening life.
Therefore,
the dislodged catheter should be removed as soon as possible,
which might be achieved with percutaneous retrieval,
open thoracotomy retrieval,
and long-term anticoagulant therapy.The common location of a dislodged catheter was the right atrium to the inferior vena cava (IVC),
the...
