[Change in indications for reconstruction of supraaortic extracranial arteries (author's transl)].

Analysis of 334 patients, operated upon from 1962 till 1976 because of obstructions of the extracranial cerebral vessels demonstrates a change in the indication for reconstruction during the last years. The aspect of prophylaxis of neurological damage by prompt reconstruction becomes increasingly important which is documented by an increase of patients which were operated upon a) in the asymptomatic stage, b) bilaterally, c) for internal carotid occlusion during the stage of increasing neurological symptoms after they were selected according to certain criteria.
