Interventional radiologic treatment for hepatic arterial occlusion after repeated hepatic arterial infusion chemotherapy via implanted port-catheter system.

The present study evaluated the feasibility of interventional radiologic treatments for hepatic arterial occlusion after hepatic arterial infusion chemotherapy (HAIC) via an implanted port-catheter system. Treatment for hepatic arterial occlusion was attempted in seven patients with unresectable liver cancer. In six, the obstructed hepatic artery was recanalized. In three patients, the recanalized hepatic artery again became obstructed. However, by performing additional interventional radiologic procedures, secondary patency of the hepatic artery was successfully obtained in two patients. In conclusion, when hepatic arterial occlusion occurs, HAIC can be resumed in the attempt to recanalize the hepatic artery.
