[Liver manifestation of circulatory disorders].

ABSTRACT

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.
