Examples
- The vena hemiazygos, also known as the left hemiazygos vein, is a continuation of the left ascending lumbar vein.
- It receives the left subcostal, left esophageal, and left bronchial veins, and crosses the midline at the 8th vertebra.
- The vena hemiazygos is often paired with the azygos vein and serves as an important vessel for the venous drainage of the thoracic and abdominal regions.
- Upon crossing the midline at the 8th vertebra, the vena hemiazygos empties into the azygos vein, ultimately contributing to the superior vena cava.
- As the vena hemiazygos continues from the left ascending lumbar vein, it assumes a vital role in draining blood from the posterior walls of the thorax and abdomen.
