Factor VII
A decrease in FVII activity significantly contributes to the coagulopathy and progressive hemorrhagic injury (PHI) in patients with isolated traumatic brain injury 1).
FVIIa and prothrombin complex concentrate (PCC) appear more effective than fresh frozen plasma (FFP).
Either FVIIa or PCC are reasonable options for reversal, but FVIIa is considerably more expensive and may have greater risk of INR rebound 2).
