What Are The Signs Of Subclavian Steal Syndrome?

Subclavian steal syndrome describes a group of symptoms that occur as the result of an obstruction in one of the large arteries that provide the arms with oxygenated blood. This shortage causes blood to be taken or stolen from the arteries that supply the patient's brain. The obstruction in the subclavian artery is typically caused by atherosclerosis-related emboli, but other uncommon cases can be caused by thoracic outlet syndrome, shunt displacement, blood clots, and large artery vasculitis. Subclavian steal syndrome is diagnosed with the use of MRI imaging, CT scan, ultrasound echo testing, physical exam, and evaluation of vital signs.
