Symptoms of a scalenus syndrome are made up of local signs of affection of the front staircase in combination with a picture of compression of the brachial plexus and subclavian artery. The development of the syndrome undergoes two stages: functional - without signs of organic changes in blood vessels and organic, when stenosis and occlusion of the subclavian artery are detected.
The main symptoms of the scalenus syndrome are associated with the reflex voltage of the anterior staircase muscle, which occurs when the third and sixth cervical roots are irritated.
In the clinical picture of the defeat of the subclavian artery, vegetative disorders are often present - pallor, acrocyanosis, sweating of the hands, trophic skin disorders, nails.
Vegetative-vascular and trophic disorders are also found in the clinical picture of the costal syndrome (Folconer-Weddle syndrome), small chest muscle syndrome (hyperabduction syndrome, Wright-Mendlovich syndrome), Personone-Turner syndrome (neuralgic amyotrophy), and Peget-Schroeter syndrome.
Among all neurovascular syndromes of the lower extremities, vegetative disorders are most vividly represented in the picture of pear-shaped muscle syndrome. Vegetative-vascular and trophic disorders are manifested by paresthesias in the zone of innervation of the sciatic nerve (chilliness, crawling sensation, tingling, numbness, decreased pulse on the arteries of the foot of the foot and in the medial malleolus, hyperhidrosis, acrocyanosis, skin pallor of the feet, decreased skin temperature, sometimes distal edema), and vegetative-vascular-trophic disorders are not gross: patients do not have gangrene, disappearance of the pulse on the arteries, thrombophlebitis, etc.
