Intracranial injury (ICI) is a leading cause of morbidity in children; however, the use of computed tomography (CT) to evaluate ICI has significant risks in children. A recent study suggests D-dimer is associated with ICI. We surveyed the performance of plasma D-dimer in ruling out ICI or skull fracture (SF) in children with head trauma. ⋯ Low plasma D-dimer (≤0.5 μg/mL) is useful to limit the use of CT in children by excluding traumatic ICI or SF.
