Liver regeneration is a fascinating process that makes living related donor transplantation feasible for patients. In this study we evaluated the change in graft volumes in living related liver transplantation (LRLT) patients by computerized tomography (CT) assisted volumetry technique. 33 patients (17 adults, 16 children) who underwent liver transplantation were included in this study. Pediatric patients were referred as group A, adult patients were referred as group B. The initial graft weight measured during operation was used as the initial graft volume. All patients’ graft volumes were calculated by CT volumetry technique retrospectively. The data was compared with the initial graft volume in each patient. Paired Samples T-Test was used for statistical analyses. The graft volume increased 2.7-285.6 % with the mean increase 78 % in group A, and 10.5-150.8 % with mean increase 89 % in group B. These changes were statistically significant (p<0,0001) in both groups. The liver regeneration of recipient grafts is more complicated than that of donors. There are a limited number of reports of complete volume recovery. We showed that volume regeneration is significant in liver grafts after transplantation and this can easily be followed by CT-assisted volumetry.
