Randomized Controlled Trial Multicenter Study
Recombinant factor VIIA in traumatic intracerebral hemorrhage: results of a dose-escalation clinical trial.
Intracerebral hemorrhages, whether spontaneous or traumatic (tICH), often expand, and an association has been described between hemorrhage expansion and worse clinical outcomes. Recombinant factor VIIa (rFVIIa) is a hemostatic agent that has been shown to limit hemorrhage expansion and which, therefore, could potentially reduce morbidity and mortality in tICH. This first prospective, randomized, placebo-controlled, dose-escalation study evaluated the safety and preliminary effectiveness of rFVIIa to limit tICH progression. ⋯ In this first prospective study of rFVIIa in tICH, there appeared to be less hematoma progression in rFVIIa-treated patients (80-200 microg/kg) compared with that seen in placebo treated patients. The potential significance of this biological effect on clinical outcomes and the significance of the somewhat higher incidence of ultrasound-detected deep vein thromboses in the rFVIIa-treated group need to be examined in a larger prospective randomized clinical trial.
