Stimulated Cerebral Blood Flow

Das vorliegende Buch enth{lt die Beitr{ge eines internationalen Symposiumszum Thema "Stimulierte Hirndurchblutung".Vorgestellt werden zun{chst neue Erkenntnisse zur Regulationder Hinrdurchblutung. Im 2. Abschnitt kommen verschiedeneMethoden zur Messung der Hirndurchblutung zur Sprache, diesowohl unter experimentellen als auch unter klinischen Bedingungengetestet wurden. Es folgt ein Abschnitt, der verschiedene M|glichkeiten zur Stimulation der Hirndurchblutungaufzeigt. Im letzten Abschnitt wird aufdie Bedeutung derstimulierten Hirndurchblutungsmessung zur Bestimmung der cerebrovascul{ren Reservekapazit{ten hingewiesen. Dieser Parameter hat nach den vorliegenden Untersuchungen klinischpraktische Bedeutung, beispielsweise f}r die Indikationsstellung bei cerebrovascul{ren Eingriffen zur Isch{mie-Prophylaxe.
