[Spontaneous dissection of cerebral arteries. I. Carotid arteries and their branches].

Artery dissection means tearing apart of its layers by blood coming inside after endothelial damage. The authors describe the prevalence of that pathology of carotid, arteries (diagnosed rarely so far), pointing to early onset age and to its multifactorial aetiology and pathogenesis. They also outline the pathomechanism of the neurological symptoms and emphasize the variety of the clinical manifestations. The diagnostic possibilities of artery dissection are also presented.
