Asymptomatic Spontaneous Migration of the Tip of Port-A-Cath System Into the Right Internal Jugular Vein: A Case Report of an Uncommon Complication.

Venous port catheters are devices that allow access to the central venous system and, in clinical practice, are used for patients who require long-term intravenous therapy. The ideal position of the catheter tip is the distal superior vena cava and can be confirmed by a postoperative chest X-ray. Complications during and after the implantation are not rare, but spontaneous migration of the catheter tip into the internal jugular vein is an uncommon complication. Catheter migration may be accompanied by neck, shoulder, and ear pain. Venous phlebitis and thrombosis, and neurological complications, can become potentially life-threatening. We report a case of a spontaneous catheter tip migration into the right internal jugular vein that was diagnosed in a random chest roentgenography. The patient was taken to the operative room, and the catheter was successfully removed.
