Atypical thoracic outlet syndrome and reverse flow thromboembolism.

[thoracic outlet syndrome]

Thoracic outlet syndrome is rare in children but may have serious consequences . Compression of the neurovascular structures at the thoracic outlet by anomalous soft tissues or cervical ribs may cause neurological deficits in the upper limb and venous or arterial insufficiency .The symptoms and signs of this condition are well documented , but we describe two patients with an atypical presentation . We review similar published cases where delay in diagnosis resulted in cerebrovascular catastrophe . Our patients presented with relatively nonspecific central nervous system symptoms and were found to have thoracic outlet compression . Both were treated by surgical decompression of the thoracic outlet , and the symptoms completely resolved with no long -lasting neurological consequences .We highlight the importance of these rare cases because of the risk of stroke and discuss the theory behind the pathological process .
