ROLE OF DYNAMIC DUPLEX IN THORACIC OUTLET SYNDROME.

Introduction: Outcome of surgery in non-specific thoracic outlet syndrome (TOS) is variable.Duplex imaging of the subclavian artery during Adson?s maneuver may help predict outcome. Patients and methods: A retrospective study of 32 cases of non-specific TOS who had preoperativeduplex imaging of the subclavian artery during Adson?s maneuver was done and theiroutcomes following surgical decompression of the thoracic outlet studied. Results: Of the sixteen cases with a positive Adson?s test, fourteen (87.5%) had a complete responseof symptoms following surgery while in the sixteen cases with a negative test, only eight (50%) had afavorable response to surgery. Conclusion: Duplex scanning of the thoracic outlet during Adson?s maneuver may help predictoutcome of thoracic outlet decompression surgery in cases of non-specific TOS.
