Hepatic arterial infusion of chemotherapy: the role of diagnostic and interventional radiology.

Hepatic arterial infusion of chemotherapy (HAIC) delivers higher local drug concentration to unresectable liver tumors with fewer significant systemic side-effects. It has been shown to produce better response rates than systemic chemotherapy and remains an important treatment option in patients with advanced, inoperable primary or metastatic hepatic tumors. Traditionally, catheters for HAIC were inserted surgically under general anesthesia. The advancement and expansion of interventional radiology have made it possible for catheter-port systems to be inserted percutaneously under local anesthesia with no significant increase in morbidity. A comprehensive review of the literature, techniques and complications of percutaneous placement of catheter-port systems for HAIC is presented in this article.
