[Embolism by ultrasound-thrombolysis (author's transl)].

By ultrasound it is possible to destroy thrombi intravascular and remove them by a hollow flexible probe at the same time. Experiments were now performed in 6 dogs with 2-9 days old thromboses in the femoral or iliac veins, to detect embolisation during ultrasound-thrombolysis. Parameters were pulmonary angiograms and lung scans. Only in one dog with a floating thrombus in the iliac vein signs of pulmonary embolism were found after thrombolysis. The controls of the other 5 dogs were normal.
