Vascular disorders of the liver are uncommon; however, with increased utility of screening methods, many are discovered incidentally. Multiple diseases affect vascular structures of the liver and the involvement may range from microscopic liver sinusoids to larger vessels such as portal vein and extrahepatic veins. The type and level of vascular involvement determines the clinical presentation of the disease. Vascular disorders of the liver have some common characteristics: patients are usually young, and some of the diseases cause significant microvascular alterations that frequently lead to non-cirrhotic portal hypertension. This triggers a compensatory increase in arterial perfusion that may result in the development of focal benign regenerative lesions such as focal nodular hyperplasia. Left untreated, some of the vascular disorders may lead to high morbidity and mortality.
