Hypoxic liver injury Ebert ECMayo Clin Proc 2006[Sep]; 81 (9): 1232-6Hypoxic liver injury is defined as a massive, but transient, increase in serum transaminase levels due to an imbalance between hepatic oxygen supply and demand in the absence of other acute causes of liver damage. It typically occurs in elderly individuals with right-sided congestive heart failure and low cardiac output. Precipitating factors include arrhythmias or pulmonary edema. Symptoms include weakness, shortness of breath, and right upper quadrant pain. Less commonly, hypoxic liver injury is seen in patients with severe hypoxemia or septic shock. Characteristically, the transaminase level is elevated 20-fold but normalizes rapidly over several days. Imaging studies reveal hypoechoic or hypodense lesions that resolve completely with reversal of the initiating event. Treatment and prognosis depend on the underlyIng disease.|Cardiac Output/physiology[MESH]|Diagnosis, Differential[MESH]|Heart Failure/complications[MESH]|Hepatitis/blood/*etiology/pathology[MESH]|Humans[MESH]|Hypoxia/*complications[MESH]|Liver/blood supply/*pathology[MESH]|Transaminases/blood[MESH] |
