title: [Fibrous-muscular and vessels anomalies revealing during surgery of the scalenus anticus syndrome].
abstract: One hundred and twenty five operations on 100 patients were performed due to the symptoms suggesting presence of the pressure on the neurovascular supraclavicular structures, although X-ray showed no evidence of cervical rib. In 15 cases of patients with so-called scalenus anticus syndrome as one of the forms of thoracic outlet syndrome (TOS) seemed to be compressing the neurovascular bundle. Scalenus mediums muscle appeared to be producing more compression of the nerve roots than did the scalenus anterior in 5 patients. Pressure from Rudimentary First Rib--in 2 cases in our series malformation of the first rib was the cause of the patient's distress. Anomalous Bands--in 4 cases anomalous bands of fibrous tissue in the supraclavicular area were the cause of compression of the neurovascular bundle Anomaleus Arteries Compressing Nerve Roots- large arteries compressed roots of trunks of the brachial plexus in four patients in our series to such an extent that it seemed these structures were the cause of the patient's symptoms. All anomalous structures were removed, good results after such surgical tactics were kept for long time in all cases. Therefore the surgeons, performing scalenotomy have to pay particular attention to the fibrous bands and anomalies in the scalene group of muscles.
