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.
The first branch of the subclavian artery; it runs up the back of the neck via foramina in the transverse processes of the cervical vertebrae and enters the cranial cavity through the foramen magnum. The right and left vertebral arteries merge along the ventral surface of the hindbrain to become the basilar artery. Branches of the vertebral artery include the anterior and posterior spinal arteries and the posterior inferior cerebellar artery. The vertebral arteries carry about 20% of the brain's blood supply, feeding the brainstem, cerebellum, and most of the posterior cerebral hemispheres.
