Abstract
Novel oral anticoagulants present challenges and uncertainties in the management of hemorrhagic emergencies. An 84-year-old man taking dabigatran presented with a subdural hematoma requiring neurosurgical intervention. Routine coagulation assays were prolonged at admission and following administration of Factor VIII Inhibitor Bypassing Activity (FEIBA). Thromboelastography (TEG(®)) was utilized to assess clot dynamics prior to placement of a subdural drain, which was safely inserted despite a prolonged thrombin time (TT). Exclusive reliance on the TT may delay necessary interventions. TEG(®) may be a valuable tool to investigate hemostasis in patients on dabigatran requiring emergent procedures.
