SURGICAL RESOLUTION OF EXTRINSIC VENOUS COMPRESSION
Should thoracic outlet decompression be performed, historically, this has usually been via the transaxillary (TA) or supraclavicular (SC) approach. The SC approach provides excellent access for surgical decompression of the brachial plexus and subclavian artery but maybe difficult to access the SV due to its location anterior to the scalene muscles and posterior to the manubrium. For this reason, a paraclavicular (PC) or an infraclavicular (IC) incision has been considered an alternative option for successful surgical management of PSS.2
