OBJECTIVE: The purpose of this study was to retrospectively compare the subclavian and femoral approaches to a fixed-catheter-tip method of implantation of a port-catheter system for hepatic arterial infusion chemotherapy with respect to complications and dysfunctions. MATERIALS AND METHODS: Between April 2006 and April 2012, 153 patients (104 men, 49 women; age range, 23-82 years; mean, 65 years) with unresectable malignant liver tumors underwent percutaneous implantation of indwelling port-catheter systems by the fixed-catheter-tip method via the left subclavian or femoral artery. The success of implantation and outcome of complications were investigated and compared between these approach routes. RESULTS: The overall technical success rate of port-catheter system implantation with the fixed-catheter-tip method was 99% (152 of 153 patients). Seventy-five patients underwent implantation with a port-catheter system via the left subclavian artery, and 77 patients via the femoral artery. Catheter dislocation occurred in 3.9% of the patients; hepatic artery obstruction, 2.6%; catheter occlusion, 3.9%; bleeding at the puncture site, 3.9%; cerebral infarction, 1.3%; and infection related to port-catheter implantation, 2.6%. No significant differences in complications and port-catheter system dysfunction between the left subclavian and femoral approaches to port-catheter system implantation with the fixed-catheter-tip method were seen in any of the parameters. In addition, cerebral infarction occurred exclusively with the left subclavian approach, whereas infection occurred exclusively with the femoral approach. CONCLUSION: Implantation of the port-catheter system with the fixed-catheter-tip method is equally feasible via both the left subclavian and the femoral approaches.
