In elderly patients with recurrent falls, the lack of a specific antidote for direct oral anticoagulants like dabigatran can lead to fatal outcomes following traumatic brain injury.
Caution in fall-prone elderly on dabigatran warranted; leaves open antidote effects on TBI outcomes.
One disadvantage of direct anticoagulant drug is the lack of an antidote, which may become relevant in patients with traumatic brain injury. A 77-years old man with atrial fibrillation and syncope received dabigatran despite recurrent falls. Due to a ground-level-fall, he suffered from subarachnoidal and intraparenchymal hemorrhages, subdural hematoma and brain edema with a midline shift. Despite osteoclastic trepanation and hematoma-evacuation he remained comatose and died seven days later without regaining consciousness. Most probably, decreased dabigatran clearance due to increased age might have contributed to the fatal course. We suggest withholding anticoagulant therapy in patients with unexplained falls. If anticoagulant therapy is deemed necessary, vitamin-K-antagonists with their potential for laboratory monitoring and reversal of anticoagulant activity should be preferred.
