Question

The anterior thoracic wall and sternum is drained by which veins?

Answer 1

The venous drainage of the anterior thoracic wall and sternum is by Anterior intercostal veins. The upper six anterior intercostal veins drain directly to internal Thoracic vein. The seventh, eight & ninth anterior intercostal veins will drain into the musculophrenic vein.

• The anterior intercostal veins originate from the intercostal space just inferior to anterior aspects of their respective ribs.

• The anterior intercostal veins are present only in the upper nine spaces. Each space contains two veins and accompanies the anterior intercostal arteries.
