Plaques of 13.5*1.5mm in size in the subclavian artery are more serious and can lead to arterial stenosis.
The most common clinical manifestations are headache and dizziness, numbness of the upper limbs and other symptoms, which should be actively treated with drugs or surgery to improve the symptoms and avoid complications.
