Diagnostic imaging plays an important role in the presurgical planning and postsurgical monitoring in related liver donors. Authors present the sort of the different imaging modalities. Before surgery, the aims of diagnostic studies are: measurement of the liver volume, assesment of the liver arterial and venous supply and detection of the focal liver findings. In our practice we use multislice CT as a method of choice. According to CT volumetry, the
mean whole liver volume of potential donors was 1437 cc, the right liver volume – 992 cc, left liver – 445 cc, segment 4 – 189 cc, segments 2+3 – 256 cc. CT angiography occured hepatic arterial variants in 36.5% of potential donors. In 41.6% cases the common trunk of medial and left hepatic veins was diagnosed, accessory hepatic veins in 40.8% cases and 8(6.4%) trifurcations
of the portal veins. Occasional focal CT findings in the liver parenchyma, benign in origin, we found in 20% cases. In general 103 hepatectomies were performed which included 89 left lateral segmentectomies, 10 left lobectomies and 4 right lobectomies. After harvestings of the segments 2+3 the mean right hepatic volume increased in course of regeneration, and segment 4 became atrophic. No important complications after surgery were seen.
