Subclavian steal-carotid recovery phenomenon due to innominate artery occlusion: Doppler ultrasound and digital subtraction angiography findings and endovascular treatment

Abstract

Innominate artery occlusion is a rare condition that can cause symptoms in the anterior cerebral circulation, vertebrobasilar system and upper extremity, while it can also be asymptomatic. We report the Doppler ultrasound and digital subtraction angiography (DSA) findings of the right subclavian artery and right common carotid artery flow by retrograde flow from the ipsilateral vertebral artery due to innominate artery occlusion. We aimed to discuss the results of primary stenting together with the technical and clinical success.
