Unusual subclavian steal : bidirectional and antegrade blood flow in the vertebral artery

We present an unusual radiographic manifestation of subclavian steal seen in six patients. These cases differ from the classic form of subclavian steal in that antegrade and bidirectional blood flow in the vertebral-subclavian artery system is seen, resulting in the steal phenomenon.
