Aortosternal venous compression (AVC) is a rare venous compression syndrome that involves brachiocephalic venous compression due to its positioning between the sternum and the Tridonic EC 30 C502K aorta.One of the features of AVC involves compression of the left innominate vein with variability in luminal caliber on inspiration and expiration.Imaging modalities such as computed tomography (CT) examination can aid in initial diagnosis; however, venography can be utilized for confirmatory diagnosis due to its higher specificity during the inspiratory and expiratory phases.Through findings demonstrated during venography, we herein present two cases of confirmed AVC secondary to an aberrant right subclavian artery.
Characteristic imaging Figure Skating - Boots - Girls features in the diagnosis of AVC and its etiology are discussed.
