Understanding how the main portal vein travels and what it sits against in the upper abdomen is key. The main portal vein is formed behind the neck of the pancreas by the union of the splenic and superior mesenteric veins. It then ascends within the hepatoduodenal ligament toward the porta hepatis to reach the liver. Along this course it lies anterior to the inferior vena cava, so the two structures are in contact as the MPV approaches the liver. This intimate relationship with the IVC is why the inferior vena cava is the structure the MPV comes into contact with. The aorta sits more to the left and posterior, and while the superior mesenteric artery crosses in front of the MPV near the pancreas, it isn’t the structure described as coming into contact in the same way.
