The azygos vein can be formed as a single root, two roots, and three roots, namely lateral, intermediate and themedial roots respectively. The hemiazygos vein and the accessory hemiazygos vein are the tributaries of azygos vein ratherthan its left side equivalents. Its variations, especially in young persons without any relevant risk factors, may result inthromboembolic illness. This study aimed to describe the morphological and morphometric variations of azygos systemof veins. The present study was conducted on thirty formalin fixed adult human cadavers by dissecting azygos vein fromformation to termination and variations were noted. The azygos vein was formed by a single root in 56.7%, by two roots:the lateral root and intermediate root in 36.7% cases and by the lateral root and medial root in 6.6%. The vertebral level oftermination of azygos vein was seen at the level of T4 vertebrae in 70% cases, at the level of T3 vertebrae in 20% of cases andat the level of T5 vertebrae in 10% cases. The course of azygos vein was varying in 13.3%. These morphological variationscan be useful while performing mediastinal surgery, mediastinoscopy, surgery of the deformations of the vertebral column,neurovascular surgeries of the retroperitoneal organs, disc herniation and fracture of thoracic vertebrae.
