Nerve Conduction Velocity and Doppler Evaluations of Thoracic Outlet Syndrome



Abstract: Eighty-one electrodiagnostic conduction studies and Doppler frequency shift evaluations of neurovascular compression through the costoclavicular space were done on 59 subjects. There is a highly significant statistical correlation between normal and abnormal conduction velocities and obstructive changes found with the Doppler unit. Both studies provide significant data in the clinical diagnosis of costoclavicular neurovascular compression disorders. Doppler frequency shift units are relatively inexpensive and may provide a simple, painless, noncomplicated method of evaluation or screening for costoclavicular neurovascular compression syndromes.
