title: [Doppler findings in intracranial vascular disorders. Differential diagnosis of extracranial and intracranial vascular occlusions (author's transl)].
abstract: Directional Doppler sonography of the carotid arteries in the neck (selective for the common carotid artery, external and internal carotid arteries) and of the supratrochlear artery permits reliable diagnoses and localizations of extracranial stenoses and occlusions of these arteries. In addition, severe intracranial vascular disorders may also be detected by these methods. Characteristic combinations of Doppler results are described in occlusions of the trunk of the middle cerebral artery, cerebral circulatory breakdown, large arteriovenous angiomas of one hemisphere and carotidcavernous fistulas, and are compared with angiographic findings. The knowledge of these Doppler findings is indispensable for the differential critical evaluation of such disorders found at the level of the neck arteries and at the fronto-orbital terminal branches of the ophthalmic artery.
