Hepatic Arterial Infusion Pump Complication With Multimodal Radiologic and Anatomic Review

Hepatic arterial infusion therapy involves surgically implanting a subcutaneous hepatic arterial infusion pump with the catheter tip at the hepatic artery. This pump directly delivers chemotherapy to the liver, which may reduce systemic toxicity, improve resectability, and treat unresectable hepatic lesions. This therapy is used in primary or metastatic hepatic malignancies. We present a case that reviews a multimodal radiologic approach to a less common complication of hepatic arterial infusion pump. Using nuclear medicine, interventional radiology, and pictographic presentation, we provide an anatomic review, demonstrate radiologic intervention capability, and show posttreatment resolution of the complication.
