Examples
- The hemizygos vein serves as a continuation of the left ascending lumbar vein, which crosses the midline at the 8th vertebra and empties into the azygos vein.
- In most individuals, the hemizygos vein can be identified as a vessel that arises from the left ascending lumbar vein and subsequently drains into the azygos vein.
- Anatomical studies have consistently shown that the hemizygos vein is responsible for bridging the left and right sides of the venous system by crossing the midline at the 8th vertebra.
- As a key tributary of the azygos vein, the hemizygos vein plays a vital role in the venous drainage of the thoracic cavity and abdominal regions.
- Radiographic imaging often reveals the hemizygos vein as a distinct vessel that traverses the midline and empties into the azygos vein at the level of the 8th vertebra.
