title: [Compensatory mechanisms in intra- and extracranial vascular occlusions (author's transl)].
abstract: Intra- and extracranial collaterals are described and are illustrated radiographically. The significance of these collaterals for cerebral blood flow, particularly in respect to possible surgery, is discussed.
