Imaging-based analysis of right inferior accessory hepatic vein variations in living donors: relevance to operative decision-making and graft outcomes

This study investigates the variations of the right inferior accessory hepatic vein (IRHV) in living liver donors and their implications for surgical planning and graft outcomes. By analyzing 200 donors using multidetector computed tomography (MDCT), the authors found that IRHV variations significantly influence hepatic venous dominance and the necessity for middle hepatic vein reconstruction, particularly in cases with larger IRHV sizes. The findings underscore the importance of accurately identifying these anatomical variations to optimize surgical strategies and enhance graft survival.
