CTICasesEmbolized Catheter Fragment in the Pulmonary Artery
Imaging findings
On a staging CT for a new abdominal cancer, an incidental catheter fragment is seen extending from the main pulmonary artery into the right upper lobe pulmonary artery branch, not attached to any other device. The patient's chest port catheter terminates in the right atrium, so the fragment's exact origin is uncertain given the absence of prior imaging or documented instrumentation.
Key takeaways
This represents an embolized catheter fragment, presumed to have sheared off from a central venous catheter, that was successfully retrieved from the pulmonary artery using an interventional radiology snare technique, illustrating catheter fracture and embolization as a potential complication requiring endovascular retrieval.
