Abstract

Background/Aims: To investigate the anatomy and variations of right lobe accessory veins and segment 5-8 veins draining into middle hepatic vein with 64 slice multidetector computed tomography (CT).

 

Materials and Methods: 100 consecutive living donor candidates underwent 64 slice CT angiography. Image interpretation was performed based on source axial images, multiplanar reformats, and three-dimensional postprocessing images by the same radiologist.

 

Results: Segment 5 and 8 veins with larger diameters were frequently found to be the proximal ones. Accessory hepatic veins were present in the great majority of cases (83%). Most of them were the inferior right hepatic veins (55%). All cases were classified according to the number of segment 5-8 veins and the presence or absence of a right accessory hepatic vein. Most of the donors had more than one segment 5-8 vein and right lobe accessory veins (57%).

 

 

Conclusion: Multidetector CT is a valuable technique for investigating the venous anatomy of the liver in living donor candidates. Anatomy and variations of the hepatic veins can easily be evaluated by using multiplanar images.
