Aberrant subclavian artery, or aberrant subclavian artery syndrome, is a rare anatomical variant of the origin of the right or left subclavian artery. This abnormality is the most common congenital vascular anomaly of the aortic arch, occurring in approximately 1% of individuals.
anatomic shunts and capillary shunts. Anatomic Shunt. exist when blood flows from the right side of the heart to the left side of the heart without coming in contact with an alveolus for gas exchange. In health lung there is a normal anatomic shunt of about 3% of the cardiac output. Caused by nonoxygenated blood completely bypassing the alveoli and entering the pulmonary vascular system by means of the bronchial venous drainage and the left atrium by way of the thebesian veins. Common abnormalities that cause anatomic shunting: Congenital heart disease, Intrapulmonary fistula, vascular lung tumors.
