Objective To re‐recognize the intrahepatic vessels and propose a new view of the hepatic segmental classification. Methods Using successive sections of 50 adult cadavers and three‐dimensional CT images of hepatic vessel of 300 patients, the branching pattern of intrahepatic vessels and hepatic segments were investigated. Results According to the branching pattern of intrahepatic vessel, the liver is divided into left and right hemilivers by the median fissure. The right hemiliver is divided into anterosuperior and posteroinferior lobes by the curved right interlobar fissure. The anterosuperior lobe is divided into ventral and dorsal segments by the vertical intersegmental fissure, and the ventral segment is divided into upper and lower subsegments. The posteroinferior lobe is divided into upper and lower segments by the horizontal intersegmental fissure. The left hemiliver is divided into posterosuperior and anteroinferior lobes by the interlobar fissure. The anteroinferior lobe is divided into medial and lateral segments by the intersegmental fissure, and the medial segment is divided into upper and lower subsegments by the horizontal subsegmental fissure. The caudate lobe is separated from other parts of the liver by the arcuate dorsal fissure. Conclusion This new method of hepatic segment division will be helpful to the precise localization of minimal lesions in the liver.
