Meta Analysis Comparative Study
Risk of thromboembolic events in controlled trials of rFVIIa in spontaneous intracerebral hemorrhage.
Recombinant activated factor VII (rFVIIa) reduces hematoma expansion and improves outcome after intracerebral hemorrhage (ICH), with an apparent increase in nonfatal thromboembolic events (TEs) with higher doses. Despite low incidences of such events in rFVIIa-treated hemophiliacs, the frequency in older patients with more atherosclerosis and immobility has yet to be defined. ⋯ There appears to be a increased risk of arterial TEs associated with higher doses of rFVIIa in ICH patients as compared with placebo. Further studies are underway to identify specific factors associated with these events and to define the dose that maximizes benefit and minimizes risk.
