[The ultrasound contrast medium levovist increases the thrombolytic effect of low frequency ultrasound].

Background: Therapeutic application of ultrasound is a promising tool to develop an alternative or additional treatment modality of acute vessel occlusion. It has previously been shown that ultrasound enhances the effect of pharmacologic thrombolytic agents and has a thrombolytic potential in "stand-alone" therapy. The purpose of this study was to determine, whether the presence of the echo contrast agent Levovist further increases the thrombolytic efficacy of ultrasound.
