Abstract
To hasten the lysis of intraventricular hemorrhages, intraventricular administration of recombinant tissue plasminogen activator (rt-PA) or urokinase has been advocated as an effective and safe treatment for patients with intraventricular hemorrhage. Until now, cases of secondary hemorrhage after intraventricular fibrinolysis, to our knowledge, have not been reported in the literature. We present a report of two patients with clinically significant bleeding complications associated with intraventricular infusion of rt-PA. Both patients, a 42-year-old woman (Patient 1) and a 70-year-old man (Patient 2), suffered from hypertensive left-sided thalamic hemorrhage with ventricular extension and ventricular dilatation. Both patients required external ventricular drainage and were treated with intraventricular rt-PA. In Patient 1, a secondary intraventricular hemorrhage occurred 20 minutes after the first instillation of 2 mg of rt-PA and was associated with a sudden loss of consciousness. Treatment with rt-PA was stopped, and the patient needed a permanent shunt. In Patient 2, intraventricular subsequent bleeding was noted 4 hours after the second 4-mg dose of rt-PA, clinically apparent as anisocoria. In Patient 2, rt-PA administrati...Continue Reading
