The objective of this article is to examine the anatomical variants of hepatic arterial vascularization by 64-slice angio-computed tomography (angio-CT). When planning the treatment of patients with Hepatocellular carcinoma that require surgery or endovascular therapy, it is useful to consider the variety of anatomical variants that are possible and it is the objective of this article to classify them using digital subtraction angiography and CT. Examples of the application of these techniques in our hospital will also be illustrated. Angio-CT has the capability of visualizing these anatomical variants and therefore enabling the selection of an optimised surgical or endovascular treatment. Interventional radiology plays a key role in advanced endovascular treatment of liver tumors. The administration of drugs and/or chemoembolizing agents often requires superselective catheterization of arteries to the tumoral mass to preserve the healthy hepatic parenchyma.


KEY WORDS: Anatomy; Hepatic artery; Multidetector computed tomography
