The collateral branches of posterior intercostal arteries arise from the posterior intercostal artery near the angle of the rib. The collateral branch travels forward within the intercostal space, keeping close to the superior border of the rib below. It is accompanied by a collateral branch of the anterior ramus of thoracic nerve (or collateral branch of intercostal nerve). It supplied blood to the thoracic wall.
