Cervical Rib and Thoracic Outlet Syndrome
ثبت نشده
چکیده
A cervical rib is a supernumerary rib that occasionally projects from the lateral mass of the 7th cervical vertebra. Clinically, it can cause obscure nervous or vascular symptoms, and it is difficult to diagnose. Studies have shown the prevalence of cervical ribs to lie between 0.03% on radiographs and 3% in postmortem investigations, depending on the sex and race of the population studied. The term thoracic outlet syndrome (TOS) refers to a heterogeneous group of disorders that compress one or more of the neurovascular elements within the thoracic outlet (superior aperture of the thoracic cavity) on their way to the axilla. Cervical ribs are congenital variants that are known to cause TOS or brachial plexopathy in up to 10% of the affected individuals. In symptomatic cervical rib, surgical rib resection may be adopted.

Isolated Cervical Rib Fracture: A Rare Etiology of Thoracic Outlet Syndrome
Isolated fracture of a cervical rib is a very rare entity and usually presents as a painless swelling or as thoracic outlet syndrome. We describe a case of a 45-year-old woman with history of fall two months back. She presented with symptoms of neurogenic thoracic outlet syndrome for one month. Isolated left cervical rib fracture was documented on X-ray cervical spine. Her fractured cervical ri...
متن کاملEvaluation of Neurovascular Complication of Cervical Ribs
Introduction: Cervical rib is relatively uncommon congenital abnormality that originates from the seventh cervical vertebrae and rarely from the sixth vertebrae. The purpose of this paper is to consider that this abnormal condition is an important cause of neurovascular compression at the thoracic outlet. Methods: In this study all patients who were referred to radiology departm...

Introduction: Cervical rib is a supernumerary rib springing from one of the cervical vertebrae, usually the seventh. About 1 in 200 people are born with cervical rib. About 1 in 10 people who have a cervical rib develop symptoms of thoracic outlet syndrome (TOS). Aims: The aim of this study was to identify normal and abnormal anatomy of thoracic outlet using MRI in symptomatic costoclavicular c...

We present the case of a 68-year-old woman, referred to our department for critical upper limb ischemia, which had occurred a few days after homolateral surgical ligamentotomy for carpal tunnel syndrome, diagnosed and confirmed by electromyography, and performed with a brachial tourniquet. The patient was later admitted for subsequent progressive necrosis of the first three fingers of the left ...
متن کاملCervical Ribs and Thoracic Outlet Syndrome
Cervical ribs are an anomaly that arise from the lowest cervical vertebrae but their relationship to thoracic outlet syndrome (TOS) is not so constant that the two conditions should be seen as synonymous. Perhaps no more than 10% of people who have cervical ribs develop TOS and the syndrome may well occur in the absence of ribs. Diagnosis of TOS may be difficult and depends upon a thorough hist...
