A patient suffering from acute left subclavian artery thrombosis presented with an unusual syndrome of prominent somnolence, right cerebellar signs, and left upper extremity ischemia. Clinical, angiologic, and electrophysiologic stud ies confirmed a brain stem and reticular formation dysfunction due to vertebro basilar ischemia. Urgent thromboembolectomy led to neurologic improvement and satisfactory revascularization of the involved upper limb.
