Figure 4From: Failed surgical ligation of the proximal left subclavian artery during hybrid thoracic endovascular aortic repair successfully managed by percutaneous plug or coil occlusion: a report of 3 cases Angiography after Amplatzer-plug deployment. (a) Selective injection of contrast medium in the distal left subclavian artery after Amplatzer-plug deployment (arrow) demonstrates a total occlusion of the proximal left subclavian artery. (b) Flush aortography after Amplatzer-plug deployment (arrows) reveals retrograde opacification (subclavian steal phenomenon) of the left subclavian artery through the retrogradely filling left vertebral artery.Back to article page
