Zusammenfassung

Die lokale intraarterielle Fibrinolysetherapie ist eine aussichtsreiche und vergleichbar komplikationsarme Therapieoption bei akuten thrombembolischen Verschlüssen der Extremitätenarterien, wenn der klinische Schweregrad der Ischämie und die Verschlusslokalisation nicht die sofortige chirurgische Revaskularisation erfordern bzw. erlauben. Die Therapieentscheidung muss unter Beachtung eventuell vorliegender Kontraindikationen für den Einzelfall im interdisziplinären Gefäßteam getroffen werden. Neben einer adäquaten Dosierung sind die streng intrathrombotische Applikation sowie ein sorgfältiges klinisches und Gerinnungsmonitoring erforderlich. Bedarfsweise kann die Lysetherapie mit Verfahren der interventionellen Thrombaspiration sowie Ballondilatation oder einer chirurgischen Korrektur einer zugrunde liegenden Läsion kombiniert werden.

Abstract

Local catheter-directed thrombolysis for thromboembolic extremity artery or bypass occlusions is a promising therapeutic option with comparatively low complication rates if the severity of the ischemia does not require an urgent surgical revascularization. This therapeutic decision has to be made by the vascular team under consideration of individual circumstances and contraindications. Apart from an adequate dosage, a strict intrathrombotic application of the fibrinolytic agent and careful clinical monitoring, including surveillance of the coagulation system is necessary. If needed, the thrombolysis therapy can be combined with interventional thrombaspiration and balloon dilatation or surgical correction of an underlying lesion.
