Figure 1

Liver (LIV) with partially dissected right lobe is seen cranially. The common hepatic duct (CHD) directly drains to the upper segment of the gall bladder (GB). From the GB the cystic duct (CD) originates and drains out as the common bile duct without joining to the CHD. The common hepatic artery is divided into the proper hepatic artery (PHA) and the gastro-duodenal artery (GDA). The portal vein (PV) is seen between the CD and the PHA. The PHA divides into left and right hepatic arteries (LHA & RHA). The cystic artery (CA) is originating from the RHA. A "bridging artery" (BA) connects the right and left hepatic arteries. An accessory hepatic artery (AH) is originating from the bridging artery, forming a "cruciate" hepatic arterial anastomosis.
