肝脏供血非常特殊，包括门静脉和肝动脉双重供血（门静脉供65%～75%，肝动脉供25%～35%），汇合于肝窦后通过肝静脉回流至体循环，累及门静脉、肝动脉和肝静脉及其分支的病变都可引起供血或引流区域肝组织缺血缺氧、门静脉高压、上消化道曲张静脉出血、肝性脑病等。肝血管疾病在临床上较为少见，诊治相对困难，本文将对肝血管系统相关疾病作一综述。“,”The liver has a very special dual blood supply, including the portal vein (65%~75%) and hepatic artery (25%~35%). The hepatic veins returns blood to the systemic circulation via the portal vein, and hepatic artery after hepatic sinusoidal confluence. The lesions on the hepatic vein and its branches can cause ischemia and hypoxia or obstruction of the drainage system, portal hypertension, upper gastrointestinal variceal bleeding, hepatic encephalopathy, and so on. Clinically, hepatic vascular diseases are relatively rare, so the diagnosis and treatment are relatively difficult. Herein, we review the diseases related to the hepatic vascular system.
