Lysebehandlung linksventrikulärer Thromben: Akut- und Langzeitergebnisse

: Intravenous thrombolysis with urokinase (60,000 U/h) was undertaken in 15 patients with large thrombi in the left ventricle (demonstrated by echocardiography) after myocardial infarction. Complete lysis was achieved in ten, partial in four. None had post-thrombolysis signs of arterial emboli, two patients developed haematuria and one had partial separation of the thrombus which required operative removal. Four patients who had a mean ejection fraction of 37 +/- 12% had died a sudden cardiac death within six months of the thrombolysis. Nine patients survived for up to four years without recurrence of thrombi: seven of them had been treated with aspirin (acetylsalicylic acid), two with coumarin derivatives. Two patients could not be followed-up. These preliminary results suggest that large left-ventricular thrombi can be successfully lysed by intravenous thrombolysis without significant complications, probably without recurrent thrombi.
