Establishment of a hepatic cirrhosis and portal hypertension model by hepatic arterial perfusion with 80% alcohol

Figure 2 Portal vein variation. A: Direct portal phlebography of experimental group 2 before perfusion showed the portal venous branches clearly; B: Portal phlebography immediately after perfusion showed a significant reduction in small portal venous branches and a widened main portal vein; C: Portal phlebography at 6 wk after perfusion showed that a large number of irregular bypass branches of intrahepatic portal veins were formed, which communicated directly with hepatic veins, and the main portal vein was still wider than that before perfusion.
