Abstract
Innominate artery steno-occlusive disease is a relatively rare clinical entity and may cause cerebrovascular symptoms. Herein, we report a 50-year-old male patient who presented with recurrent syncopal episodes and cerebrovascular ischemia. Color Doppler sonography revealed a distinctive flow pattern with partial and total flow reversal in the right internal carotid artery and vertebral artery, respectively. Further angiographic evaluation revealed complete occlusion of the innominate artery. Endovascular stenting was successful and enabled normal antegrade flow in the right common carotid and vertebral artery.
