肝脏是人体内实质器官中血供最丰富,代谢率最高的器官。肝血流量约占心排出量的25%。肝血管受门静脉和肝动脉的双重供应,肝动脉供血占30%,门静脉供血占70%~[1]肝血管瘤是肝脏最常见的良性肿瘤,其中大多数为海绵状血管瘤~[2]。因此肝血管瘤手术与其他部位血管瘤手术相比难度及复杂程度增加数倍。肿瘤直径在10 cm~15 cm为巨大血管瘤,>15 cm为特大血管瘤,对此两类患者均应进行手术
The liver is the most abundant blood supply and highest metabolic rate in the parenchyma of the human body. Liver blood flow accounts for about 25% of cardiac output. Hepatic vessels are doubly supplied by portal and hepatic arteries, with hepatic artery blood supply accounting for 30% and portal vein blood supply accounting for 70%. [1] Hemangiomas are the most common benign tumors of the liver, most of which are cavernous hemangiomas [2] . Therefore, hemangiomas surgery and other parts of the hemangioma surgery compared to the difficulty and complexity increased several times. Tumor diameter of 10 cm ~ 15 cm for the huge hemangioma,> 15 cm for the large hemangioma, both types of patients should be operated on
