[Long-term course of aortic arch syndrome caused by arteriosclerosis].

The course of the extracranially conditioned cerebrovascular disease is characterized by a worse prognosis in comparison with the average population of the GDR (11 years older) and by increased cardiovascular complication rate (every fifth patient suffered a myocardial infarction, every fourth patient suffered an apoplexy). Younger age of manifestation and increasing number of concomitant diseases form the basis of a course which is altogether endangered by complications, which, however, compared with peripheral and coronary arteriosclerosis, is more favourable. Operative reconstruction of the path of a vessel leads to an enduring improvement of the picture of the complaint. The total prognosis corresponds to the so-called spontaneous course. Under permanent treatment with anticoagulants a retardation of the general progressing of arteriosclerosis and improvement of the survival rates is to be proved.
