Hepatic vascular diseases are a heterogeneous group of uncommon liver disorders. The goals of this educational exhibit are: - To identify the usual CT imaging features in the hepatic vascular syndromes. - To provide brief notes about the clinical and pathophysiological correlation of the radiological findings.

Vascular diseases of the liver can result from various conditions involving the hepatic vascular system of the hepatic artery, portal vein or hepatic veins. Diagnostic imaging plays an important role for the correct diagnosis in the majority of such cases. The imaging features of these conditions reflect not only their particular etiology, but also the specific hepatic parenchymal changes depending on the grade, level and duration of the hemodynamic changes associated with the different vascular alteration. We can distinguish hepatic inflow from hepatic outflow diseases....

Hepatic infarction Hepatic infarction is defined as an area of coagulation necrosis from hepatocyte cell death caused by local ischemia, which in turn results from the obstruction of circulation to the affected area [1]. Itis an extremely rare situation because of the liver supply. Hepatic infarction can occur when there is both hepatic arterial and portal vein flow compromise; in fact, in most cases, it results from either insult to the hepatic artery or portal vein thrombosis superimposed on hepatic arterial occlusion [1]. It may...

A broad spectrum of variants and pathologic conditions can involve the liver vasculature. Imaging is essential for the evaluation of the normal hepatic vascular anatomy, as well as for the determination of the patency of the vessels and the diagnosis of abnormalities. Familiarity with the pathogenesis and imaging features of these vascular entities can aid the radiologic diagnoses and guide appropriate patient management.
