Color Doppler Ultrasound with sagittal and axial planes on case 2 (Type 2). Note: a: The abdominal aorta, mesenteric artery, extension of mesenteric vein and also the extrahepatic portal vein that directs to the head and posterior region of the lateral segment. At hepatic hilum level there is an evidence of the inferior vena cava and an increased caliber of hepatic artery. b: The sagittal and paramedian planes show two retro hepatics paths of the portal extrahepatic vein (along the venous ligament). c: Ultrasound in axial plane, in the level of the confluence of the hepatic veins to IVC and cross-section of the inferior vena cava, the extrahepatic portal vein door and the abdominal aorta
