RESUMO
OBJECTIVE: To report 3 cases of subdural bleeding associated with rivaroxaban managed by 3-factor prothrombin complex concentrate (PCC3). CASE SUMMARIES: Case 1 presented with a 1-cm thick subdural hematoma (SDH) 12 hours after her last dose of rivaroxaban. Case 2 presented with a right 1-cm acute right SDH with 2 to 3 mm of midline shift 24 hours after his last dose of rivaroxaban. Case 3 presented with a 1.8-cm thick right cerebral convexity hematoma 12 hours after her last dose of rivaroxaban. All patients received 23 to 35 units/kg PCC3 with 1 to 3 units of fresh frozen plasm (FFP) and demonstrated no progression in lesions measured by repeat computed tomography (CT). Two patients were discharged to rehabilitation facilities and 1 patient ultimately died due to the location of the lesion. DISCUSSION: Rivaroxaban has no specific antidote. Current bleeding management strategies are based on expert opinion. The risks and benefits for differing strategies are unclear, and no clinical experience has been reported to date. These cases begin to illuminate differences among choices for managing bleeding associated with Xa inhibitors. CONCLUSION: In this case series, 25 to 35 units/kilogram PCC3 and FFP 1 to 3 units ceased rivaroxaban-associated bleeding without thrombogenic complications.
