subclavian steal syndrome

A phenomenon caused by a partial blockage of one of the main arteries that gives branches to the head and then to the arms. Use of the arm may divert blood from the head, leading to VERTIGO, headache, uncontrollable deviation of the eyes, double vision, nausea and vomiting. There is a serious risk of STROKE.

Stent coverage of the left subclavian origin in such procedures results in perfusion of the left subclavian artery by way of the subclavian steal phenomenon from a normally positioned left vertebral artery, as demonstrated in Fig.
This will preclude the subclavian steal phenomenon from occurring so as to perfuse the left subclavian artery; consequently, surgical re-implantation of the left subclavian artery to the left carotid artery would be mandatory.
