PURPOSE: This case report describes utilization of thromboelastography (TEG) in the setting of an acute major bleed in a patient on dabigatran who had concomitant acute kidney injury. SUMMARY: An 80-year-old female presented to the emergency department after a fall with complaints of pain in her knee, shoulder, and hip. Her medical history was significant for coronary artery disease, for which she took clopidogrel 75 mg daily, and atrial fibrillation, for which she took dabigatran 150 mg twice daily. The physical exam was remarkable for pain within the shoulder, hip, and knee, which had swelling and ecchymosis that extended into the right thigh. Given the possibility of compartment syndrome with multiple possible etiologies of coagulopathy, TEG and computed tomography angiography (CTa) of the right lower extremity were performed. The initial TEG showed prolonged R time and activated clotting time, indicating clotting factor dysfunction with no additional coagulopathy noted, including antiplatelet effects. On the basis of the TEG and CTa findings, it was decided to reverse dabigatran with 5 grams of idarucizumab. Approximately 1 hour after administration of idarucizumab, the patient was taken to interventional radiology where a limited angiogram of the right lower extremity showed no active extravasation. Because of the patient's renal dysfunction and the possibility of rebound hypercoaguability, repeat TEG tests were ordered at 4 and 8 hours after the initial reversal to ensure clearance of idarucizumab-dabigatran complexes. The repeat TEG values showed complete reversal of the initial coagulopathy noted. During the admission, the patient required no blood transfusions or surgical interventions and all her initial laboratory results improved. CONCLUSION: Serial TEG testing was successful at managing multiple coagulopathies in a patient at risk for trauma-induced compartment syndrome.
