Preoperative imaging study of patient 2. (A) Contrast-enhanced computed tomography scan and (B) coronal image of multidetector-row CT show the tumor from the proximal to the distal portion of the bile duct (arrows). (C,D) Three-dimensional angiography with multidetector-row CT shows a left-to-right reversal of the vascular arrangement and that the common hepatic artery arises from the SMA and runs behind the SMV. Ao, aorta; CA, celiac artery; CHA, common hepatic artery; ERBD tube, endoscopic retrograde bile duct drainage tube; GB, gallbladder; PV, portal vein; SMA, superior mesenteric artery; SMV, superior mesenteric vein; St, stomach.
