DELAYED BRACHIAL-PLEXUS PARALYSIS DUE TO SUBCLAVIAN PSEUDOANEURYSM AFTER CLAVICULAR FRACTURE

Injuries to the brachial plexus and subclavian artery are serious comp lications of shoulder girdle trauma. Due to the close anatomical relat ionship between the brachial plexus and the subclavian artery in the t horacic outlet, both structures are often simultaneously involved in s houlder girdle injuries. Isolated lesions of the subclavian artery or the brachial plexus can also occur, especially with clavicular fractur es. When a false subclavian aneurysm leads to a gradually increasing c ompression of the brachial plexus, the neurological signs and symptoms develop insidiously after the traumatic event.
