Dr Omar Bashir et al. The hepatic veins are three large veins which drain the hepatic parenchyma into the inferior vena cava (IVC), named the right hepatic vein, middle hepatic vein and left hepatic vein. The veins are important landmarks, running in between and hence defining the segments of the liver.
The superior vena cava is a large vein located in the upper chest, which collects blood from the head and arms and delivers it back to the right atrium of the heart. If this vein is compressed by outside structures, or if a thrombus or clot develops within it, return blood flow to the heart is impeded.
