Zusammenfassung
Ziel einer Embolisation ist der Verschluss eines Blutgefäßes durch Blutflusssenkung und Thromboseinduktion. Dafür stehen verschiedene Materialien zur Verfügung: Metallspiralen, Gewebekleber (flüssiges Embolisationsmaterial) oder Partikel (partikuläres Embolisationsmaterial) oder auch durch eine Kombination verschiedener Materialien. Die Wahl des Embolisationsmaterials richtet sich nach: Blutungslokalisation, Blutungsausmaß, Gerinnungsfunktion und Gefäßart und Gefäßterritorium sowie Kollateralperfusion. Es werden Indikationen und Kontraindikationen, verschiedene Materialien und deren Einsatzbereiche vorgestellt. Daneben gibt das Kapitel Auskunft über typische Komplikationen (Katheterverklebung, Coil-Fehlplatzierung) und deren Management. Zur Durchführung von Embolisation, Lyse oder Thrombektomie kann fast jeder angiografische Standardkatheter verwendet werden; peripher gelegene, kleine Zielgefäße erfordern jedoch den Einsatz von Mikrokathetern. Für diese sind jedoch Erfahrungen mit verschiedenen Führungskathetern und -drähten genauso wichtig wie eine adäquate Kathetertechnik. Im Unterkapitel „Mikrokatheter: Tipps und Tricks“ finden sich eine umfangreiche tabellarische Zusammenfassung der Embolisationsmaterialien diverser Hersteller.
