[Thoracic outlet syndrome: an unusual postoperative complication]. / Le syndrome du défilé thoraco-brachial: une complication post-opératoire inhabituelle.

UNLABELLED: Introduction. Neurogenic Thoracic Outlet Syndrome (NTOS) is a chronic lower trunk brachial plexus entrapment caused by a cervical rib or a fibrous band. True NTOS is rare and progresses usually slowly. Case report. A 12-year-old girl complained of numbness and weakness of the right upper limb immediately after an orthopedic surgical procedure for scoliosis. Neurological and neurophysiological features were both consistent with a neurogenic thoracic outlet syndrome (NTOS). CONCLUSION: This observation illustrates the risk of NTOS after certain surgical procedures, especially when a prolonged prone position with abducted shoulders is required.
