Abstract Purpose The correlation between right hepatic vein (RHV) diameter and inferior RHV (IRHV) incidence and that between IRHV incidence and other clinical features remain unclear. We investigated factors correlated with IRHV incidence as well as provide a simple and reliable method for predicting IRHV presence preoperatively. Methods We obtained computed tomography (CT) imaging data of 1980 patients from the Department of Radiology, Qingdao Municipal Hospital, from July 1, 2016, to July 1, 2017. We excluded patients with heart disease, inferior vena cava (IVC) disease, history of liver surgery or trauma, space-occupying lesions in the liver, and other diseases, which can cause hepatic hemodynamic changes. CT images of patients were three-dimensionally reconstructed. We measured RHV and IRHV diameter as well as the angle between the RHV and the IVC. Results Data on 299 patients were included in this study; the incidence of IRHV was 34.44%. Sex, age, and the angle between the RHV and IVC did not correlate with IRHV incidence. RHV diameter negatively correlated with IRHV incidence (P 8.86 mm, but is present with RHV diameter
