Hepatocellular carcinoma often metastasizes along the portal venous system, necessitating precise anatomical resection.Anatomic resection (AR) involving segments S6 and S7 aims to enhance oncological efficacy while preserving liver volume.The intersegmental veins (IVs) between these are potential landmarks that facilitate accurate determination of plane.Three-dimensional (3D) reconstruction technology was used analyze IVs in 164 patients who underwent contrast-enhanced computed tomography (CT).The incidence IVs, their characteristics, spatial localization, correlation with diameter right hepatic vein (RHVs) were examined.IVs identified 71.95% patients, primarily connecting RHV.They converged middle-lower portion RHV.The most clearly identifiable junctions RHV located at midpoint horizontal planes second region center gallbladder bed.Patients a larger-diameter more likely have draining into (Type 1), smaller-diameter correlated inferior (IRHV) 2).The prevalent feasible for AR.When IRHVs coexist, predicts type present.IVs precision determining transection during AR S7, potentially reducing blood loss enhancing patient safety.Further research is needed validate findings address limitations sample size hemodynamic variations.
