LOS ANGELES – For intraventricular hemorrhages of at least 20 mL, alteplase (Activase – Genentech) delivered directly into the clot by external ventricular drain almost doubles the odds of achieving a modified Rankin Score of 0-3 by 6 months.
More clot is removed – and patients with large intraventricular hemorrhages (IVHs) do better – with more vigorous alteplase dosing and when more than one drain is used.
The findings come from the Clot Lysis Evaluation of Accelerated Resolution (CLEAR III) trial, which randomized 249 IVH patients to 1 mg alteplase every 8 hours for up to 12 doses, and 251 to saline on the same schedule, delivered by external ventricular drain. The intervention didn’t make much difference with small hemorrhages.
In a video interview at the International Stroke Conference, investigator Dr. Issam Awad, a professor of surgery and neurology and director of neurovascular surgery at the University of Chicago, explained how to do the technique correctly for larger clots, and the expected benefits.
