Mild Head Trauma in the Emergency Room: Assessment of the Risk of Intracranial Hemorrhage in Patients Receving Platelet Inhibitors.

Mild Head Trauma in the Emergency Room: Assessment of the Risk of Intracranial Hemorrhage in Patients Receving Platelet Inhibitors.

The clinical signs presented by a patient with a mild head injury are highly variable but remain strongly predictive of brain damage. The reference examination for the diagnosis of post-traumatic intracranial hemorrhage is currently the cerebral scanner without injection of contrast medium. Magnetic resonance imaging (MRI) tends to surpass CT in equipped centers, except for suspected bone lesions. The time required to perform brain imaging depends on the patient's clinical condition, comorbidities and treatments.

The responsibility of antiplatelet agents in post-traumatic intracranial hemorrhage is currently discussed, particularly with aspirin.

The hypothesis is that there is no significant difference in the proportion of intracranial hemorrhage in patients on antiplatelet agents after mild head trauma, in the absence of other factors favoring the occurrence of intracranial hemorrhage.
