The azygos vein was dilated and appeared to be the continuation of inferior vena cava (IVC) (Figure 1b) and drained into superior vena cava. The infrarenal segment of the IVC was normally positioned and after receiving the left and right renal vein continued as azygos vein passing into superior vena cava (Figure 1a-b). After draining the hepatic veins, the suprahepatic segment of IVC opened into right atrium (Figure 1d).
