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
