[Surgery of the extracranial cerebral vessels. (Indication and results)].

Surgery of the extracranial cerebral vessels nowadays under right indication and operative technique is one of the most satisfying areas of vascular surgery. Our present status of indication is shown in table 1; it should be pointed out that the classical indication is a lesion of the internal carotid artery with a Transitoric Ischemic Attack, but also in cases of progressive stroke with acute carotid occlusion the operation will be successful relentless of any time limit as long as the patient is conscious. For the extrathoracal bypass procedure we now prefer the subclavio-subclavian bypass to the formerly performed carotio-subclavian bypass.
