The PV and its branches lie behind the hepatic artery and bile duct branches in the hepatoduodenal ligament. The RHD and LHD unite in the hilar plate, close to the right end of the porta in front of the right branch of PV to form the CHD. The CHD has a variable length from 1.0 cm to 7.5 cm depending on the site of joining of the cystic duct, which in a normal course joins the right side of the CHD in 85-90% of the cases. The PHA divides into two branches near the left border of the CHD/common bile duct CBD. The LHA proceeds toward the porta hepatis to the left of CHD and at the porta hepatis lies behind the LHD. The RHA enters the hepatocystic triangle posterior to the CHD and ascends anterior to the PV till the division of PV into the right and left branches and follows a relation posterior to the right hepatic duct (RHD) upward into the right lobe of liver
