Movement of the side hole occurring in a port-catheter system percutaneously implanted for hepatic arterial infusion chemotherapy.
The authors report a case in which catheter-related difficulties occurred with a port-catheter system implanted to perform repeated hepatic arterial infusion chemotherapy for advanced hepatocellular carcinomas. The port-catheter system had been percutaneously implanted with the catheter tip fixation method, and a side hole had been created in the indwelling catheter for placement in the common hepatic artery. Four months after port-catheter placement, however, the indwelling catheter became bent at the location of the side hole in the proper hepatic artery. Subsequently, the side hole moved into the left hepatic artery, resulting in a lack of distribution of chemotherapeutic agents to the tumours in the segments of the liver supplied by the right hepatic artery. This situation was easily corrected with a simple interventional radiological method so that hepatic arterial infusion chemotherapy could be resumed with sufficient distribution over the entire liver. To our knowledge, such a problem involving a port-catheter system implanted with the catheter tip fixation method and its management thereafter has not been reported in the published literature.
