dc.description.abstractHepatic arterial variations are relatively common, but usually overlooked by radiologists, leading to iatrogenic complications or prolonging interventional or surgical procedures. Michels in 1966 classified hepatic arterial variations in 10 categories, based on a cadaveric study. Establishment of multidetector computed tomography (MDCT) provides useful anatomical information. The purpose of our study is to highlight these variations and to propose of a user-friendly algorithm when studying a CT examination. We studied 1,520 contrast-enhanced CTs (16-row MDCT system) during arterial phase and searched for hepatic arteries and celiac trunk (CTr) variations. CT images were postproccessed using multiplanar reconstruction, maximum intensity projection and volume rendering techniques in axial, sagittal, and coronal planes. Our results were organized according to Michels' classification. Normal anatomy was found in 72.89% of the cases and variations classified in Types II–X in 22.24%. However, 4.87% of the cases could not be classified in Michels' types. A single arterial variation was found in 22.89% of the cases and multiple arterial variations were found in 4.21% of the cases. We examined first the aorta for supernumerary branches and then checked the fissure between right and left liver lobe, following porta hepatis, and finally the CTr and superior mesenteric artery. Hepatic arteries and CTr variations are relatively common (27.11%) and should be identified by the radiologists when studying CTs as their recognition provides better surgical planning, preventing iatrogenic complications. Imaging in coronal plane was helpful for end branches, while sagittal plane was better for aortic branches. Clin.
