Abstract
Azygos systems of veins are not accompanied with the corresponding arteries. The azygos system communicate with the caval system infront and with the vertebral venous plexus behind. Then the formation and level of the formation of the azygos vein was noted. The compressed diameter of the trunk of the azygos vein was measured close to its formation and termination by sliding callipers. The level of the azygos arch was observed and noted. The course of the azygos vein was observed with reference to midline of the vertebral column and the level of inferior and superior crossing of the azygos vein with reference to the thoracic vertebral level was noted. The level of termination of the hemiazygos vein and accessory hemiazygos vein were noted for each specimen. The azygos vein, after beginning on the right side of the vertebral column ran upwards and to the left to cross the midline, having ascended a variable distance on the left side of the vertebral column, it returned to the right side, thus crossing the midline again to reach its normal termination in the superior vena cava. Thus the azygos vein crosses the midline twice showing inferior and superior crossing.
