Hepatic nodal hypoperfusion is a descriptor of an imaging test, which usually indicates the presence of hemodynamic abnormalities in the liver and requires prompt medical treatment.
Hepatic nodal hypoperfusion is usually caused by some pathologic factors, which leads to the decrease of portal venous blood flow and the obstruction of hepatic venous reflux, resulting in the opening of abnormal channels or potential traffic branches, and then abnormal changes in hepatic hemodynamics occur, which is mainly manifested by the decrease of perfusion in the distribution of liver segments and lobes within the liver parenchyma, and ultimately leads to the reduction of the local arterial blood supply to the liver.
Hepatic nodal hypoperfusion changes are most commonly seen in inflammation, congenital anomalies, benign and malignant tumors, portal or hepatic vein embolism, etc. If there are no obvious symptoms or abnormalities on examination, regular review and follow-up is sufficient. If there is any discomfort or other examination suggests abnormality, timely consultation and treatment should be sought.
