The patient, male, 43 years old, underwent radical gastrectomy half a year ago. He was diagnosed as metastatic cancer of the right lobe of the liver in the first half month of interventional therapy. He was transferred to our department for interventional treatment of hepatic carcinoma. We used conventional methods to select the hepatic duct to the common hepatic artery and did a subtraction. The patient’s proper hepatic artery was not ideally filled and was thinner than normal. The left and right arterial trunks were developed, but the branches were not developed and the tumor was not clearly stained. then?
