Direct portography technique and rabbit liver portal anatomy. (A) Exposition of the small bowel after laparotomy, showing a branch of the superior mesenteric vein (white arrow). (B) Direct portography shows the conventional liver rabbit portal anatomy: the original portal vein (OPV) divides into the main portal vein (MPV) and caudate portal vein (CPV). The MPV then bifurcates into the right portal vein (RPV) and left portal vein (LPV) which subsequently divided into medial left portal vein (MLPV) and lateral left portal vein (LLPV).
