RationaleAcute subdural hematoma (ASDH) occurs after tearing of bridging veins within the dura resulting in the accumulation of blood between the arachnoid and dura layers within 72 hours after traumatic head injury. Also, antigen fibrin D-dimer (DD) is the principal enzymatic degradation product of cross-linked fibrin by plasmin. We observed that early tranexamic acid (TXA) treatment resolved hyper-fibrinolysis and rapid disappearance ASDH.Patients ConcernsA 48-year-old female presented with unconsciousness for 2 hours after head trauma. Her Glasgow Coma Scale score was >8 points.DiagnosisComputed tomography scan established ASDH with midline shift and brainstem compression and surgery was scheduled. Also, laboratory results indicated high DD spike of 34,820 μg/L and a reduction in plasma fibrinogen 1 hour after the injury.InterventionShe was treated with intravenous TXA immediately after admission.OutcomesHer DD spike decreased remarkably in 48 hours with associated rapid disappearance of ASDH thereby averting surgical intervention. She recovered fully with no long-term complications.LessonsHistorically, hyper-fibrinolysis is associated with poor outcome in head trauma. However, early initiation of TXA which is noninvasive treatment modality for ASDH could avert surgery and reduce cost, anesthesia, and other complications associated with surgery.Copyright © 2023 the Author(s).
