第一、先天性发育异常，肝血管瘤的发生是先天性肝脏末梢血管畸形所致。在胚胎发育过程中，由于肝血管发育异常引起血管内皮细胞异常增生形成肝血管瘤。第二、激素刺激学说，女性的青春期、怀孕、口服避孕药等可使血管瘤的生长速度加快认为女性激素可能是血管瘤的一种致病因素，还有毛细血管组织，感染后容易变形导致毛细血管扩张，肝组织局部坏死后血管扩张形成空泡状，其周围的血管充血扩张，肝内区域性的血循环停滞导致血管形成海绵状扩张。

What is the cause of hemangioma of the liver
First, congenital dysplasia, The occurrence of hemangioma of the liver is caused by congenital vascular malformation of the terminal of the liver. During embryonic development, As a result of the abnormal development of the liver blood vessels, endothelial cells proliferate abnormally to form hemangioma of the liver. Second, the theory of hormone stimulation, Female adolescence, pregnancy, oral contraceptives and so on can accelerate the growth of hemangioma. Female hormones may be a pathogenic factor of hemangioma, And capillary tissue, After infection, it is easy to deform and cause telangiectasia, After local necrosis of liver tissue, the blood vessels expanded to form vacuoles, The blood vessels around it are congested and dilated, Regional stagnation of blood circulation in the liver leads to cavernous expansion of blood vessels.
