目的分析肝癌的动脉供血特点。方法分析有完整血管造影资料的肝癌患者366例，肝右叶肿瘤287例，肝左叶肿瘤49例，横跨左右叶者30例。常规行腹腔动脉、肠系膜上动脉数字血管造影，对可疑病例加行膈动脉、胃左动脉、脾动脉、右肾动脉、胸廓内乳动脉、支气管动脉等数字血管造影。结果参与肿瘤供血动脉，1条者157例（42．90％），2条者136例（37．16％），3条者57例（15．57％），4条者14例（3．82％），6条者2例（0．55％）。肝右动脉占50．71％（319／629），肝左动脉占26．39％（166／629），肝中动脉占1．27％（8／629），左膈动脉占0．79％（5／629），右膈动脉占6．20％（39／629），肠系膜上动脉占2．86％（18／629），胃左动脉占6．36％（40／629），胃十二指肠动脉占4．29％（27／629），右肾上腺动脉占0．64％（4／629），右支气管动脉、脾动脉、右胸廓内乳动脉均各占0．16％（1／629）。结论肝癌的血供来源以多动脉为主，除肝动脉供血外，非肝动脉分支的寄生供血也常见。

英文摘要：

Objective To analyze characteristic of arterial blood supply of liver cancer. Methods There were 366 cases of liver cancer patients with integrated angiography record. There were 287 cases of right lobe, 49 cases of left lobe, 30 cases of bilocular involvement. Routine celiac artery and superior mesenteric artery digital angiography were carried out. In doubted cases the following artery angiographies were included： phrenic artery, left gastric artery, splenic artery, right renal artery, internal thoracic （internal mammary） artery and branchial artery. Results For the number of tumor feeding artery, single artery was 42.90% （ 157/366 ） , two arteries was 37.16% （ 136/366）, three arteries was 15.57% （57/366）, four arteries was 3.82% （ 14/366 ）, six arteries was 0.55% （2/366）. Among them, right hepatic artery was 50.71% （319/629）, left hepatic artery was 26.39% （166/629）, middle hepatic artery was 1.27% （8/629）, left phrenic artery was 0.79% （5/629）, right phrenic artery was 6.30% （ 39/629 ） , superior mesenteric artery was 2.86% （18/629） , left gastric artery was 6.36% （40/629）, gastroduodenal artery was 4.29% （ 27/629 ）, right suprarenal artery was 0.64 （ 4/629 ）, right branchial artery, splenic artery, right internal thoracic （ internal mammary） artery was 0. 16% （1/629） respectively. Conclusions The blood supply for liver cancer demonstrates a multiple-arterial pattern, ectopic arteries are usually presented in addition to the hepatic artery.
