Four-dimensional CT-guided transcatheter removal of a fractured migrated catheter of a totally implantable venous access port

Patients undergoing chemotherapy usually undergo placement of a totally implantable venous access port (TIVAP), but TIVAP catheter fracture is rare. We encountered a case where flushing the TIVAP catheter became impossible because of resistance. A 61-year-old-woman underwent TIVAP placement. Although a chest X-ray revealed the fractured catheter had migrated into the right hilar area, the timing of the fracture was unclear. Four-dimensional computed tomography (4D-CT) showed that the tip of the fractured catheter was located at the anterior segmental artery of the right upper lobe and was immobile, with the remaining portion flapping with the blood flow. Transcatheter removal of the migrated catheter was judged to be possible and was performed successfully. 4D-CT may be useful as an appropriate approach in transcatheter removal of a migrated fractured catheter.
