Abstract

The hepatic artery can be involved by a variety of pathology and diseases. Today MDCT enables high quality imaging
of the hepatic artery using axial, MIP and volume rendered images. We illustrate MDCT findings of anatomical variations,
aneurysm, dilatation, dissection, arteriovenous fistula, thrombosis and stenosis. Aneurysms can be saccular,
fusiform and multiple and may develop due to atherosclerosis, vasculitis, trauma and biopsy. Dilatation of hepatic
artery can be seen in portal hypertension, Osler-Weber-Rendu disease and hemangiomatosis. Hepatic artery can be
occluded after trauma and transplantation. Dissection develops due to atherosclerosis, Marfan and Ehler Danlos
syndromes and during pregnancy. Arteriovenous fistula can be congenital and acquired. We conclude that various
hepatic artery pathologies can be confidently diagnosed by MDCT.
