Carotid stenosis / stenosis throat vessels
A narrowing of vessels (= stenosis) of the throat area is called carotid stenosis in case of a stenosis of the arteria carotis interna, or stenosis of arteria vertebralis if the spinal artery is affected. Arteria carotis interna is the artery that supplies the brain with blood. Often two characteristic points of the carotid artery are affected, namely the carotid bifurcation (at height of the 1./2. cervical vertebral body) and/or carotid siphon. Not treated, the carotid stenosis can cause apoplectic stroke at worst that often leads to paralyzations or death.
Symptoms carotid stenosis / stenosis of throat vessels
Carotid stenosis can cause the following symptoms:
- visual disturbances of one eye of the afflicted side with sudden, temporary blindness (so-called amaurosis fugax = temporary blindness)
- paralyzation of one side of face and/or arm, clumsiness of one hand (the symptoms are contralateral, i.e. that the opposite side of the vessel is paralyzed, e.g., in case of right carotid the left part of the face or body)
- in face or arm or the half side of the body: sensory disturbances, feeling of numbness
- language disorder
Dizziness or vertigo is no symptom of carotid stenosis since the vestibular organ is supplied by another vessel (the so-called vertebral arteries).
