CT Evaluation of Anatomical Variants of Hepatic Arteries: Impact on Endovascular Treatment Planning

Abstract

Tortora S, Gorga G, Maggi L, Valconi E, Floridi C and Carrafiello G

The objective of this article is to examine the anatomical variants of hepatic arterial vascularization by 64-slice Angio-TC. When planning the treatment of patients with HCC 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 (DSA) 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 tumours. The administration of drugs and/or chemo embolizing agents often requires super selective catheterization of arteries to the tumoral mass to preserve the healthy hepatic parenchyma.
