A case of indwelling catheter dislocation into the duodenum during hepatic arterial infusion chemotherapy

Abstract

A 44-year-old man underwent hepatic arterial infusion chemotherapy and systematic chemotherapy using fluorouracil (5-FU) for recurrent liver metastasis of colon cancer. He reported upper back pain 38 weeks later. Arteriography using a port system revealed a dislocated catheter tip in the second part of the duodenum. Conservative therapy using antibiotics was employed without removing the catheter tip. Various complications related to intrahepatic arterial infusion chemotherapy have been reported. Catheter chip dislocation is rare, but can sometimes become a severe complication, thereby warranting careful follow-up after hepatic arterial infusion chemotherapy.
