Occlusion of the subclavian artery

Occlusion of the subclavian artery is caused by the stenosis of the subclavian artery proximal to the site of the vertebral artery distal; It manifests itself in the physical tension of the upper shoulder girdle (seizure syndrome). Pathogenetically, the change in blood flow through subclavian and vertebrobasilar vessels is important (see above). Symptoms: loss of consciousness, dizziness, paresis, weakness of the oculomotor musculature, speech and swallowing disorders, recurrent pain in the nape. Neurological symptoms are provoked by the work of the hand. The quality of the pulse and blood pressure is different on the right and left hands. In the course of the subclavian artery stenotic noise is determined. In angiography, narrowing, occlusion II, the effect of stealing is determined, which is recognized by the retrograde contrast current in the vertebral artery of the affected side.
