Background: Mild traumatic brain injury (TBI) is a common event and antiplatelet therapy might represent a risk factor for bleeding. Objective: The aim of this study was to evaluate the risk of intracranial hemorrhage (ICH) after mild TBI in patients on antiplatelet therapy through a systematic review and meta-analysis. Methods: We conducted a systematic review and meta-analysis of prospective and retrospective observational studies on patients with mild TBI on antiplatelet therapy vs. those not on any antithrombotic therapy. The primary outcome was the risk of ICH in patients with mild TBI based on the first computed tomography scan. Secondary outcome was the risk of mortality and neurosurgery. Results: Nine studies and 14,545 patients were included. The incidence of ICH ranged from 3.6% to 29.4% in the antiplatelet group and from 1.6% to 21.1% in the control group. Patients on antiplatelet therapy had a higher risk of ICH after a mild TBI compared with patients that were not on antithrombotic therapy (risk ratio 1.51; 95% confidence interval 1.21–1.88). No difference was found in the composite outcome of mortality and neurosurgery. Conclusions: Patients on antiplatelet therapy have an increased risk of ICH after mild TBI compared with patients not on antithrombotic therapy. However, the risk is just slightly increased, and the need to perform a computed tomography scan in patients on antiplatelet therapy after a mild TBI should be evaluated case by case, but always considered in patients with other risk factors.
