目的：肝脏异位动脉供血是肝癌介入治疗中常见的现象，本文就胰弓在肝癌介入治疗中的意义及超选择方法作一介绍。方法：分析１８７例肝癌患者胰弓动脉供血情况，对有明显胰弓供血者用向左两弯导管进行超选择插管，成功者行化疗栓塞。结果：１８７例患者中肝脏主要血供来自胰弓的有１１例，（约占５．９％）。而其中８例肝总动脉呈“单向活瓣状闭塞”。１１例患者均顺利超选择至下胰十二指肠动脉并进行有效化疗栓塞。结论：肝脏经胰弓获得血供是肝总动脉闭塞后常见的现象，可应用向左两弯导管能顺利超选择至下胰十二指肠动脉对肝癌进行有效化疗栓塞。
OBJECTIVE: Liver heterotopic arterial blood supply is a common phenomenon in interventional treatment of liver cancer. This article presents the significance of pancreatic bowel in the interventional treatment of liver cancer and the method of superselection. METHODS: The pancreatic arterial blood supply of 187 patients with hepatocellular carcinoma was analyzed. For patients with significant pancreatic bowel hyperselection, catheters were placed on the left two bends. Successful embolization was performed. RESULTS: Among the 187 patients, there were 11 cases of major hepatic blood supply from the pancreas arch (about 5.9%). Among them, 8 cases of hepatic artery showed “one-way flap-like occlusion.” All 11 patients were successfully superselected to the lower pancreaticoduodenal artery and performed effective chemoembolization. Conclusion: The blood supply from the pancreas of the liver is a common phenomenon after occlusion of the common hepatic artery. It can be applied to the left two bend catheters to successfully select the lower pancreatic duodenal artery for effective chemoembolization of liver cancer.
