[Characteristics of blood flow in the vertebral arteries in scalenus anticus syndrome].

The authors studied hemodynamics in the vertebral arteries in 62 patients with the scalenus-anticus syndrome by means of radioconstrast angiography and ultrasonic angiography which produced a colour image of the vessels with calculation of the diameter and the linear and volume blood flow rate. The results of the study showed that in constriction of the subclavian artery to 60% of its diameter in the typical place, the volume blood flow rate in the vertebral arteries remained normal (184 +/- 6.9 ml/min) but reduced 1.5-2 times during the functional test. Adequate surgical correction restored normal hemodynamics, control ultrasonic angiography recorded increase of the volume blood flow rate in the vertebral values to normal values. Ultrasonic angiography provides authentic information on the character of affection of the subclavian artery in the scalenus-anticus syndrome and makes it possible to appraise the hemodynamic significance of affection of the vertebral arteries. Besides, the method allows objective evaluation of the efficacy of treatment and quantitative characteristics of hemodynamics.

[Surgical treatment of the scalenus anticus syndrome].

The purpose of this study was to assess the results of decompression of the thoracic outlet due to scalenus anticus syndrome and thus to give recommendation for a safe and effective surgical treatment. Over a 20-years period 100 patients (125 operations) underwent thoracic outlet decompression. There were 77 females and 23 male, with a median age 29 years (13-45), 4 pediatric patients were under 16 years. Of the 125 affected limbs, the indications for surgery were combination of both neurological and vascular symptoms in 55 patients, neurological symptoms in 21, and 24 patients had vascular symptoms alone. 54 patients had a transient ischemic attacks (TIA) due to the disturbance of the blood flow in the vertebral arteries, and 4 cardialgia due to the reduced blood flow in the thoracic internal arteries. From the results of this study we concluded that supraclavicular scalenectomy is a safe and effective procedure for most patients with scalenus anticus syndrome.

[Efficacy of transecting the anterior scalene muscle in the scalenus anticus syndrome (syndrome of the scalene muscle)].

The authors observed 111 cases with the anterior scalenus syndrome. Ninety-three patients underwent surgical treatment. Acknowledging the predominant role of the anterior scalenus muscle in the pathogenesis of this disorder the authors performed scalenotomia. In the group of patients with a noncomplicated development of the disease (48 cases) the operation appeared to be effective in 93.7% of the cases, while in vascular complications (45 cases) the effectiveness of the operation was significantly reduced. A positive result in these cases was attained only in 51.1%. On the basis of these data the authors come to the conclusion that scalenotomia performed in the initial, noncomplicated stages of the disease is a good prophylactic measure for severe complications in the magistral vessels and is an effective method of treatment of the scalenus-anticus syndrome.

Classic neurogenic thoracic outlet syndrome in a competitive swimmer: a true scalenus anticus syndrome.

Neurogenic thoracic outlet syndrome (TOS) is caused by compression of the lower brachial plexus usually by a cervical rib or a fibrous band. We describe a 16-year-old girl with weakness and wasting of her right hand, which progressed over the ensuing years. She had been a competitive long distance freestyle and butterfly swimmer since age 8 years. A neurological exam at age 20, revealed severe atrophy and weakness of all intrinsic right hand muscles, more so of the thenar muscles, and hypesthesia along the ulnar aspect of the hand and forearm. EMG, which showed a severe chronic axon loss lower trunk brachial plexopathy with minimal fibrillations, was typical for classic neurogenic TOS. Chest and cervical spine X-rays and MRI of the cervical spine were normal. A supraclavicular exploration confirmed the absence of a cervical rib or band. The lower trunk was thickened under the scalenus anticus which was sectioned. Neurolysis was also done. She was advised to abandon swimming. A clinical and EMG follow-up 2.5 years later showed no significant changes. This is the first case of true neurogenic TOS caused by scalenus anticus compression occurring in a competitive swimmer.

[Fibrous-muscular and vessels anomalies revealing during surgery of the scalenus anticus syndrome].

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.

Thermal asymmetry of the upper extremity in scalenus anticus syndrome, leg-length inequality and response to chiropractic adjustment.

OBJECTIVE: To describe a case of a vasomotor, vascular form of thoracic outlet syndrome that causes upper extremity thermal asymmetry, and to discuss a single subject case study (N-of-1) comparing the correlation of a subjective test for putative atlas vertebral subluxation complex (supine leg-length inequality) with a single blinded objective measurement [temperature differential (delta degree T)] on the dorsum of the hands. CLINICAL FEATURES: A 71-yr-old woman with a cold, painful right hand and chronic neck pain sought chiropractic evaluation. There was a left head tilt and muscular hypertonicity with fibrous bands in the opposite scalenes and sternocleidomastoid. Thermographic examination revealed a large temperature differential (12 degrees F) between the dorsum of the right and left hands, with the superficial veins on the dorsum of the cold hand collapsed. Thoracic outlet provocation tests were negative. A left-side leg-length inequality potentially indicative of putative upper cervical subluxation was also noted. A diagnosis of presumptive thoracic outlet syndrome with vasomotor vascular complications subsequent to altered cervical biomechanics was made. INTERVENTION AND OUTCOME: Treatment was limited to chiropractic, upper cervical, vectored, linear adjustment of the atlas vertebra. Temperature differential between the hands improved significantly after individual atlas adjustment(s) and in the long term. CONCLUSION: Scalenus anticus syndrome and upper extremity thermal asymmetry may result from altered cervical biomechanics caused by atlas vertebral subluxation complex. Furthermore, the supine leg check may be of value in determining the necessity of atlas adjustment.
