We demonstrate an overview of the vasculature of the hepatic hilum, an anatomically important part of the liver. Extending the hepatic hilum from the right end of the hepatoduodenal ligament attachment to the left end of the fissure for the ligamentum venosus, which is located at the end of the hepatogastric ligament attachment, we could easily understand the vascular structures that enter and leave the liver. We should emphasize the importance of the plate system, when we analyze the kinetics of hepatic blood flow as well as the vascular network in the hepatic hilum. Spatial recognition of the normal vascular arrangement in the hepatic hilum and knowledge about a wide variety of anatomical subtypes would be helpful to improve the clinical practice of IVR.
