SEPs are useful for evaluation of brachial plexopathy and traumatic plexopathies. In thoracic outlet syndrome, SEPs are of limited value with regard to the neurogenic variety of plexopathy and have no established value in diagnosis of the nonneurogenic (ie, vascular) variety. The value of SEPs in preventing or minimizing intraoperative damage of the peripheral nervous system is unproven.
