[Survey after correction of carotid stenosis (author's transl)].

Since 1962 until 1976 we have performed 335 operations on the carotid artery in 268 patients. In 1977 we were able to obtain information from 265 patients. The early mortality in stage I, II and IV was one to three percent, in stage III 40 percent. The cumulative survival rate after four years was 74 percent. The main causes of death were cardiac diseases. Often the patients also had heart failure, peripheral arterial diseases, hypertension, and diabetes. Following the operation at least one third of the patients had an improvement of their symptoms.
