    BackgroundA significant portion of patients sustaining traumatic brain injury (TBI) are on antiplatelet medications. The reversal of P2Y12 agents after intracranial hemorrhage (ICH) remains unclear. The aim of our study is to evaluate outcomes after TBI in patients who are on preinjury P2Y12 inhibitors and received a platelet transfusion.MethodsWe analyzed our prospectively maintained TBI database from 2013 to 2016 and included all patients with isolated ICH who were on P2Y12 inhibitors (Clopidogrel, Prasugrel, Ticagrelor). Regression analysis was performed adjusting for demographics and injury parameters. Outcome measures included progression of ICH, adverse discharge disposition (skilled nursing facility), and mortality.ResultsA total 243 patients with ICH on preinjury P2Y12 inhibitor met our inclusion criteria and were analyzed. Mean age was 55 ± 18 y, 58% were males and 60% were white and median injury severity score was 13 [9-18]. 73.6% received platelet transfusion after admission. The median packs of platelet transfusion were 1 [1-2] units. After controlling for confounders, patients who received platelet transfusion had a lower rate of progression (OR: 0.68, P = 0.01) and decreased rate of neurosurgical intervention (OR: 0.80, P = 0.03). Overall mortality was 12.3%. Patients on P2Y12 inhibitors who received platelet transfusion had lower odds of discharge to a skilled nursing facility (OR: 0.75, P = 0.02) and mortality (OR: 0.85, P = 0.04).ConclusionsPlatelet transfusion after isolated traumatic ICH in patients on P2Y12 inhibitors is associated with improved outcomes. Platelet transfusion was associated with decreased risk of progression of ICH, neurosurgical intervention, and mortality. Further randomized studies to validate the use of platelet transfusion and define the optimal dose in patients on P2Y12 inhibitors are warranted.Copyright © 2018 Elsevier Inc. All rights reserved.
