BACKGROUND Recent studies have highlighted the unfavorable prognosis of patients with spontaneous intracerebral hemorrhage (ICH) who have received prior antiplatelet therapy (PAP). Platelet infusion therapy (PIT) is commonly administered to such patients at many medical institutions, but its efficacy remains a subject of debate. METHODS To address this uncertainty, we conducted a comprehensive search of PubMed, EMBASE, and Cochrane Library databases for eligible studies published before June 30, 2023. Our primary outcomes of interest were favorable functional outcome and mortality, while secondary outcomes included the incidence of hematoma expansion and adverse events associated with PIT. Meta-analysis was performed using Review Manager 5.3. RESULTS Our analysis included 1 randomized controlled trial (RCT) and 6 retrospective studies, involving a total of 577 patients. Pooled analysis revealed that PIT did not contribute to a better favorable functional outcome at the 3-month follow-up (OR = 0.49, 95% CI 0.27-0.89) among ICH patients with PAP. Furthermore, PIT did not significantly reduce the risk of mortality (OR = 0.79, 95% CI 0.40-1.55) or hematoma expansion (OR = 1.15, 95% CI 0.65-2.01). Notably, no significant differences in serious adverse events were observed between patients who underwent PIT and those who did not. CONCLUSIONS Based on the available evidence, there is no indication that PIT can enhance the prognosis of spontaneous ICH patients with prior antiplatelet therapy, although this treatment approach appears to be safe. Therefore, routine recommendation of PIT for ICH patients with prior antiplatelet therapy is not warranted.
