Catheter fracture and embolization from totally implanted venous access ports--case reports

Totally implanted venous access ports are excellent devices for delivering chemotherapeutic agents and prolonged intravenous infusions in patients with cancer. Catheter fracture and embolization are rare and potentially serious complications of these widely used devices. Retrieval of the embolized fragment is generally indicated but may not be possible. The authors report three cases of catheter embolization in their center over a period of 9 years. Catheter "pinch-off," fracture, embolization, and retrieval are discussed.
