[A complication with hepatic arterial infusion chemotherapy--a case of sepsis related to catheter tip dislocation to the duodenal bulb].

: Extra-arterial dislocation of a catheter is one of the complications with hepatic arterial infusion chemotherapy. The authors report a case of sepsis related to catheter tip dislocation to the duodenal bulb. A 69-year-old man underwent sigmoidectomy for sigmoid colon cancer and partial hepatectomy for synchronous metastasis to the liver. We performed hepatic arterial catheterization via the femoral artery, and the patient underwent prophylactic hepatic arterial infusion chemotherapy with 5-FU. Thirty months later, computed tomography during arteriography (CTA) using a port system revealed the dislocation of catheter tip to the duodenal bulb. He showed no symptoms, so we kept him under observation. Sepsis occurred because of the dislocated catheter 39 months later. After removal of the catheter, the symptoms of sepsis disappeared.
