dc.description.abstractDuring selective transfemoral catheter cerebral angiography, anastomoses between external carotid branches and the vertebral artery, between the vertebral and deep or ascending cervical arteries, and between the middle meningeal and ophthalmic arteries can be demonstrated fairly frequently in patients with no known vascular abnormalities. One can occasionally show bidirectional filling of these anastomoses depending on the vessel injected. Visualization of these anastomoses occurs to a variable degree and is sometimes entirely technique-dependent, reflecting a transient increase in the intraluminal pressure during the injection of contrast medium.-Thus, demonstration of extracranial collateral arterial flow during cerebral angiography should not necessarily be interpreted as an abnormal phenomenon, such as may be seen with arterial occlusive disease, vascular malformation, or a very vascular tumor. Au cours de l'angiographie cérébrale parcathétérismes sélectifs par voie fémorale, peuvent apparaître des anastomoses entre des branches carotidiennes externes et l'artère vertébrale, entre l'artère vertébrale et les artères cérébrales profondes ou ascendantes et entre l'artère méningée moyenne et l'artère ophtalmique. Occasionnellement, on peut mettre en évidence un remplissage bidirectionnel de ces anastomoses, en rapport avec le vaisseau injecté. La visualisation de ces anastomoses se produit de facon variable dépend parfois entièrement de la technique, reflétant une augmentation transitoire de la pression dans l'artère durant l'injection du produit de contraste. Par conséquent, l'observation d'une circulation artérielle collatérale extracrânienne pendant une angiographie cérébrale ne représente pas nécéssairement un phénomène anormal tel qu'on le rencontre dans les troubles artériels occlusifs, dans les malformations vasculaires et dans les tumeurs vascularisées. Während der selektiven transfemoralen Katheter-Angiographie können sich Anastomosen zwischen Externa-Gefäßen und der A. vertebralis, zwischen der A. vertebralis und tiefen oder aufsteigenden cervicalen Arterien und zwischen der A. meningica media und der A. ophthalmica darstellen. Diese Befunde finden sich auch bei Patienten, bei denen keine Gef:aßanomalien vorliegen. Gelegentlich wird ein bidirektionaler Kontrastmitteldurchfluß durch diese Anastomosen nachgewiesen, dabei ist die Kontrastmittelfüllung von der Lokalisation der Kontrastmittelinjektion abhängig. Es zeigt sich also, daß diese unterschiedlichen Durchströmungen technisch bedingt werden können und nicht immer als abnormales Phänomen gedeutet werden können.en_US
