Neurogenic Thoracic Outlet Syndrome Caused by Vascular Compression of the Brachial Plexus: A Report of Two Cases
نویسندگان
چکیده
Thoracic outlet syndrome (TOS) is caused by compression of the brachial plexus and/or subclavian vessels as they pass through the cervicothoracobrachial region, exiting the chest. There are three main types of TOS: neurogenic TOS, arterial TOS, and venous TOS. Neurogenic TOS accounts for approximately 95% of all cases, and it is usually caused by physical trauma (posttraumatic etiology), chronic repetitive motion (functional etiology), or bone or muscle anomalies (congenital etiology). We present two cases in which neurogenic TOS was elicited by vascular compression of the inferior portion of the brachial plexus.

An unusual case of neurogenic thoracic outlet syndrome
INTRODUCTION Neurogenic thoracic outlet syndrome (nTOS) is the most common manifestation of thoracic outlet syndrome (TOS), accounting for more than 95% of cases. It is usually caused by cervical ribs, anomalies in the scalene muscle anatomy or post-traumatic inflammatory changes causing compression of the brachial plexus. CASE PRESENTATION We present an unusual case of nTOS caused by a cysti...
متن کاملWork-Related Neurogenic Thoracic Outlet Syndrome: Diagnosis and Treatment.
Outcomes of surgery for neurogenic thoracic outlet syndrome (NTOS) in workers' compensation are poor in a majority of patients, partly due to nonspecificity of diagnosis. Most cases have no objective evidence of the presence of brachial plexus dysfunction. Up to 20% of patients experience a new adverse event. Objective neurologic signs and electrodiagnostic evidence of brachial plexus dysfuncti...
متن کاملThoracic outlet syndrome.
Diagnosis and treatment of thoracic outlet syndrome (TOS) involves neurologists, physiatrists, family physicians, orthopedic surgeons, vascular surgeons, thoracic surgeons, neurosurgeons and sometimes psychiatrists. It is generally accepted that TOS is caused by compression of brachial plexus elements or subclavian vessels in their passage from the cervical area toward the axilla and proximal a...

We report a rare case of multiple hereditary exostosis where patient presented with bilateral base of neck exostoses with concurrent compression of brachial plexus and subclavian artery and vein. The patient was a young 26-year-old woman with chief complaints of pain in the left upper extremity, paresthesia in the left ring and little finger, and weakness in hand movement and grip. On referral,...
متن کاملArterial thoracic outlet syndrome secondary to hypertrophy of the anterior scalene muscle
Thoracic outlet syndrome (TOS) was first introduced in literature by Peet et al. in 1956. Since then is has been studied extensively and subcategorized into at least four closely related syndrome. Neurogenic TOS due to the compression of brachial plexus, arterial TOS in cases of compression of the subclavian artery, venous TOS in cases of compression of the subclavian vein, and non-specific typ...
