Abstract
Compression of the subclavian artery in the thoracic outlet is a well-known phenomenon. In rare cases, bone abnormalities, such as pseudarthrosis of the clavicle, can cause arterial compression at this level. Pseudarthrosis may develop as a result of trauma, which is the more common form, or it may be congenital. Here, the authors describe the case of a 44-year-old patient with critical ischemia of the right upper limb. She had a history of untreated right clavicle fracture at 9 months of age which had progressed to pseudarthrosis and extrinsic compression of the subclavian artery causing occlusion. The segment of the clavicle involved was resected and late thromboembolectomy of the subclavian, brachial, distal arteries was performed, with good results.Entities:
