Resection and reconstruction for hilar cholangiocarcinoma involving portal vein or hepatic artery. (A) Hilar cholangiocarcinoma involving the portal bifurcation. (B) Resection has been performed, with portal end-to-end anastomosis. (C) Hilar cholangiocarcinoma involving the right hepatic artery. (D) Resection and reconstruction with end-to-end anastomosis between the right hepatic artery stump and the proper hepatic artery. Reconstruction is also possible using a rotating arterial graft with any of the named arteries in the picture. Finally, reconstruction with a radial artery graft or a saphenous vein graft is also possible (not depicted).
