A. Trifurcation of the portal vein
B. Bifurcation of portal vein in the right lobe of the liver
C. Aberrant right hepatic artery

Trifurcation of portal vein is not a contraindication of  left lobe liver transplant  as we will get a single portal vein on the left side

Portal vein trifurcation
Portal vein

Bifurcation of portal vein in right lobe does not matter because we are leaving the right lobe behind

Right post duct draining into left duct gives rise to two ducts on the left or a single duct which is quite high.

Right posterior duct to left
