What Are The Signs Of Subclavian Steal Syndrome?

Hands With Circulation Issues

Individuals affected by subclavian steal syndrome may have hands with circulation issues. This occurs due to the reduced supply of blood to the arm when the subclavian artery becomes fully or partially obstructed. This symptom occurs in patients who overexert their affected arm with exercise or occupation related movements. This symptom is confirmed by measuring blood pressure in both arms and observing the difference. Symptoms of ischemia in the brain stem and brain are more common than circulation issues in the hands of affected individuals. Although the subclavian artery steals blood, the supply sometimes does not end up being enough to provide oxygen to all of the vessels in the arms and hands. Patients who have circulation problems in their hands precipitated from subclavian steal syndrome can experience claudication, or pain due to a lack of oxygen to the muscle cells. Muscle weakness can occur in the hands due to a lack of sufficient blood flow as well as paresthesia. The hands may turn white or blue in response to poor circulation or feel cold to the touch.
