Occlusion of the Left Superficial Femoral Artery During Hepatic Arterial Infusion of Chemotherapy for Liver Metastases from Colon Cancer 18 Months After the Implantation of a Port System: a Case Report

We report a case of complication of a catheter port system. A 67-year-old male who had undergone left hemicolorectomy and partial hepatectomy for liver metastases from colon cancer underwent hepatic arterial infusion (HAI) of chemotherapy by a percutaneously implanted catheter port system to prevent recurrence. Eighteen months after the implantation of a port system he complained of intermittent claudication. Intravenous digital subtraction angiography (IVDSA) showed occlusion of the left superficial femoral artery. The catheter was removed and a femoro-popliteal bypass with an artificial graft was constructed. Thrombus was found around the indwelling catheter at the insertion site. After the operation his complaint disappeared and has been alive without recurrence for 6 years.
