分析了９４例胃十二指肠动脉参与原发性肝癌侧支供血的介入放射学资料，将其侧支供血途径分为５类：（１）胃十二指肠动脉分支接触供血；（２）胆管周围侧支供血；（３）肠系膜上动脉经胰十二指肠动脉弓分支供血；（４）交通支供血；（５）变异供血，参与侧支供血的胃十二指肠动脉内经与肝癌大小呈正相矢关系。
The interventional radiology data of 94 cases of gastroduodenal artery involved in the collateral blood supply of primary liver cancer were analyzed, and the collateral blood supply channels were divided into 5 categories: (1) gastroduodenal artery branch contact blood supply; (2) Peripheral bile duct collateral blood supply; (3) Superior mesenteric artery via pancreaticoduodenal artery branch; (4) Transbronchial blood supply; (5) Variant blood supply; Gastroduodenal artery internal circulation involved in collateral blood supply The size of liver cancer is a positive phase vector relationship.
