Percutaneous Removal of a Broken and Embolized Transvenous Chemotherapy Port Catheter in the Left Pulmonary Artery by Using a Snare-loop Catheter

Abstract

Totally subcutaneous intravascular portacath provide safe and reliable vascular access and is widely utilized for venous access for long-term parenteral administration of medications. Catheter fracture and/or embolization of the catheter fragment in to the heart and or pulmonary artery is a rare and potentially serious complication. When it occurs, a prompt surgical or percutaneous extraction of the embolized foreign body is necessary. We present an asymptomatic case of metastatic colon adenocarcinoma in a patient who had fragmentation of catheter from the connection of the port and migration to left pulmonary arteries. We successfully removed the 10-cm long and 6-Fr diameter fractured catheter segment from the left pulmonary artery via the right femoral vein using a snare catheter with triple loop without complication. Post-procedure course was uneventful and the nature of the vascular access made early ambulation possible. Compared to surgery, percutaneous approach is a less invasive, safe, reliable and effective technique. Therefore, we suggest that percutaneous transcatheter technique for retrieval of embolized or broken catheter fragments should be considered as the first-choice treatment.
