In patients with symptomatic subclavian artery stenosis, angioplasty plus stenting was found to be superior to angioplasty alone or bypass in terms of asymptomatic survival and freedom from reintervention [12]. Alternatively, patients may present with dizziness, diplopia, ataxia, or syncope due to the reversal of blood flow in the vertebral artery in order to steal blood from the brain [5]. 189194, 2001. 264267, 2014.

Delayed or decreased amplitude pulses and bruits in the subclavicular fossa are physical findings which could be a clue to SCA stenosis. Functional Radiography in Examination of Spondylolisthesis. Often if a scaphoid fracture is suspected and not seen on plain film, a follow-up will be performed in 7-10 days 1. The Borden Classification of dural arteriovenous malformations or fistulas, groups into three types based upon their venous drainage: LAO would favor centering laterally towards the right), laterally to include the medical third of both clavicles, inferior to include the sternoclavicular joints and part of the manubrium, superior to include the entirety of the sternoclavicular joint, the sternoclavicular joint of interest will be central to the image without foreshortening, the opposite join will appear foreshortened and obscured by the bony thorax.
