Occlusion of the proximal left subclavian artery
Case Discussion
Imaging showed occlusion of the proximal left subclavian artery and retrograde flow in the ipsilateral vertebral artery on Doppler (ultrasound images not available). Unfortunately the chronically occluded segment could not be recanalized by endovascular techniques from either above (brachial approach) or below (groin approach), so he went on to have bypass surgery.
