“…Similarly, Yang et al reported a weak negative correlation between the RHV diameter and the IRHV diameter. 4 According to our results, the presence of an RHV greater than 9.36 mm in diameter detected the absence of IRHV at a sensitivity of 54% and specificity of 71.2%. Therefore, a thin RHV should alert clinicians to the presence of IRHV.…”

“…Reconstruction is not required for IRHVs with a diameter of less than 5 mm, while there is a need for surgical reconstruction in those with a diameter of 5 mm or above. 9 It has been reported that there is a negative correlation between the presence of IRHV and the RHV diameter, 1,4 which is even more important considering the possibility of a diameter mismatch in RHV anastomosis.…”

“…2,3 Prevention of acute complications, e.g., necrosis and hepatic failure, and chronic complications, such as atrophy, is only possible with the complete venous drainage of each segment of the liver. 4 The morphological and functional anatomy of the liver differs. Morphologically, it is divided into the right and left lobes by the falciform ligament.…”

Background Right hepatic venous anatomy, right lobe volume, and percentage of remnant liver are issues to be considered in preoperative planning especially transplantation. Objectives The aim of this study was to investigate the relationship of the presence of the inferior right hepatic vein (IRHV) with the right hepatic vein (RHV) diameter, right lobe volume, and percentage of remnant liver. Materials and Methods In this cross-sectional study, the computed tomography (CT) images of 90 patients who underwent triphasic CT for being living liver donation were evaluated retrospectively. The number and diameter of IRHVs and the diameter of main RHV were recorded. For the liver volume analysis, a deep learning-based automatic liver segmentation (Hepatic VCAR) program was used. A virtual hepatectomy plane was drawn, where the right and left liver volumes were found and the percentage of the left lobe to the total liver volume was calculated. Pearson's correlation analysis was used for correlation analysis and Student's t-test was used to compare parameters. Results A total of 74 IRHVs were detected in 53 (58.88%) of 90 patients. There were no differences in the percentage of remnant left lobe volume, right lobe volume, and RHV diameter between the IRHV (+) and (−) groups. The RHV diameter had a weak negative correlation with the IRHV diameter, and a weak positive correlation with the right lobe volume. Conclusions The percentage of remnant left lobe volume, right lobe volume, and RHV diameter did not differ in liver donors with and without an IRHV. The RHV diameter had a weak negative correlation with the IRHV diameter and a weak positive correlation with the right lobe volume.
