“…The Cochrane Central data base search retrieved no additional studies. Full-text versions of these 36 studies were obtained, and 14 studies were excluded for the following reasons: 1) They did not offer a comparison criterion standard clinical examination, [12][13][14] 2) the exact number of patients could not be extrapolated from the methodology or results for analysis, 15,16 3) the study consisted of an exclusively pediatric population, 17-20 4) the article was a single-patient case report, [21][22][23] or 5) the study primarily focused on TCD analysis in populations with structural defects of the cranium (ie, patients with external ventricular devices or postdecompressive hemicraniectomy). 24,25 In the final presentation of the literature search results, there was no conflict or disagreement between 2 reviewers (J.J.C.…”

“…Im Gegensatz zur Dopplersonografie ermöglicht die transkranielle Duplexsonografie durch die Darstellung des Hirngewebes, das die intrakraniellen Arterien umgibt, den Nachweis der Penetration des Ultraschalls durch den Schädelknochen und die Lokalisation der intrakraniellen Arterien jeweils unabhängig vom Vorliegen eines Blutflusses in diesen Arterien. Als Signalverstärker eingesetzte Ultraschallkontrastmittel erhöhen die Sensitivität der Duplexsonografie, um die für einen zerebralen Zirkulationsstillstand charakteristischen Strömungssignale an den intrakraniellen Arterien nachzuweisen [28,29]. Biphasische Strömungssignale (oszillierende Strömungssignale) sind nur dann vereinbar mit einem zerebralen Zirkulationsstillstand, wenn das Integral (Fläche) der anterograden und retrograden Anteile des Dopplerfrequenzzeit-spektrums innerhalb eines Herzzyklus gleich ausgeprägt ist; es wird aber nicht gefordert, dass hier eine Messung durch das Ultraschallgerät erfolgen soll, in der Praxis wird das durch den Untersucher abgeschätzt [1] Ein Fehlen der Strömungssignale bei transkranieller Beschallung der Hirnbasisarterien kann nur dann als sicheres Zeichen eines zerebralen Zirkulationsstillstandes gewertet werden, wenn derselbe Untersucher bei gleicher Geräteeinstellung bei einer früheren Untersuchung eindeutig ableitbare intrakranielle Strömungssignale dokumentiert hat oder wenn an den extrakraniellen hirnversorgenden Arterien (Aa.…”

“…▼ "In contrast to Doppler sonography, transcranial duplex sonography makes it possible to detect the penetration of ultrasound through the cranial bone and to determine the location of the intracranial arteries regardless of the presence of blood flow in these arteries by visualizing the brain tissue surrounding the intracranial arteries" [1]. "Signal-enhancing ultrasound contrast agents increase the sensitivity of duplex sonography to detect the flow signals in the intracranial arteries that are characteristic for cerebral circulatory arrest" [1,39,40]. In Germany, only the ultrasound contrast agent SonoVue ® (Bracco Imaging Deutschland) is approved for contrast-enhanced ultrasound (CEUS) in cases in which ultrasound examination without contrast agent is not diagnostic.…”
