The Thoracic Outlet Syndrome test is conducted in order to determine the vascular role when the patient's symptoms are indicative of loss of perfusion or neurogenic causes.
This procedure tests for intermittent loss of perfusion, particularly in the arms and hands.
Either Doppler, PVR or PPG sensors detect normal resting waveforms in the digits or hands and then the patient is instructed through a sequence of positions such as: Hands-up Test, Adson or Scalene Maneuver, Costoclavicular Maneuver, Allen Test, and Provocative Elevation Test. The clinician tries to identify a position which significantly reduces perfusion to determine whether the symptoms originate from vascular causes.
