Therapeutic embolization of the hepatic artery was performed in 60 patients with nonresectable malignant liver tumors. Atypical topographical anatomical variants of the arterial system of the liver were revealed in 10 of them (16.7%). In 8 patients two hepatic vessels, one coming out of the celiac artery, the other--out of the upper mesenterial or left gastric artery supplied a tumor with blood. In three of them one vessel was embolized, in five patients both arteries were embolized. The blocking of the entire blood flow of a tumor brought about a positive clinical effect in all the patients. Embolization of one blood-supplying artery alone led to no improvement. A conclusion was made of a necessity to achieve arterial devascularization of the entire tumor tissue area during intravascular therapy.
对60例不可切除的肝脏恶性肿瘤患者进行了肝动脉治疗性栓塞。其中10例（16.7%）发现肝脏动脉系统存在非典型的局部解剖变异。8例患者中，一条发自腹腔动脉，另一条发自肠系膜上动脉或胃左动脉的肝血管为肿瘤供血。其中3例栓塞了一条血管，5例患者两条动脉均被栓塞。阻断肿瘤的全部血流在所有患者中均产生了积极的临床效果。仅栓塞一条供血动脉未带来改善。得出结论，在血管内治疗期间有必要实现整个肿瘤组织区域的动脉去血管化。
