Subclavian steal syndrome is a vascular disorder in which occlusion or stenosis of the subclavian artery proximal to the vertebral artery origin (which is the subclavian artery) causes altered vascular haemodynamics that result in retrograde blood flow in the ipsilateral vertebral artery toward the upper arm, distal to the subclavian artery narrowing, where decreased blood pressure had been established and is associated with transient neurologic symptoms related to cerebral ischemia.
