The liver is abundant in blood supply and receives 25% of the cardiac output via the hepatic artery and portal vein. Circulatory disorders may cause hepatic injury, resulting in congestive hepatopathy(CH) and ischemic hepatitis(IH). Hepatic congestion arising from increased hepatic venous pressure and decreased cardiac output is the common pathophysiological basis of both CH and IH. In addition, extensive arteriovenous shunts affect portal pressure and cardiac function, leading to alterations of hepatic blood supply. The current review summarizes the pathophysiology, clinical manifestations and therapeutic interventions of the above diseases, in order to provide reference for clinical practice.
肝脏血供丰富，接受肝动脉和门静脉双重血供，约占心输出量的25%，循环系统疾病可导致肝脏受损，各种原因所致右心功能不全可引起肝脏回流障碍从而导致淤血性肝病，而急性循环功能和呼吸功能衰竭可导致缺血性肝脏损伤。除此之外，广泛的动静脉分流可引起门静脉压力及心功能异常，亦可造成肝脏血供异常。现简要介绍以上疾病的发病机制、临床表现及治疗方法，以期为临床诊治提供帮助。.
