Clinical Routine in Thoracic Outlet Syndrome

Study Overview
=================
Brief Summary
-----------------
Transversal recording and analysis of investigations performed in patients referred for suspected thoracic outlet syndrome (TOS)

Detailed Description
-----------------
Patients will have recording on a database of all investigations that were eventually performed for the diagnosis or follow up of their disease, among which: Characteristics (Age, Gender height, weight, ongoing treatment , professional activity, sports activity, Symptoms. Forearm and finger photoplethysmography (PPG) during provocative maneuvers of the upper limb Transcutaneous oxymetry (Tcpo2) recording Standard questionnaires (MASC, DASH, FS36) Doppler and ultrasound during provocative maneuvers of the upper limb Angiography during provocative maneuvers of the upper limb Electromyogram Standard X-ray
