RESUMO
Chemodenervation with botulinum toxin (BTX) has been recommended for focal spasticity. BTX injection should be performed with caution in patients with bleeding disorders and/or receiving anticoagulation therapy. We present a case of BTX injection for post-stroke spasticity in a patient with hemophilia A who could not take oral spasmolytics due to chronic hepatitis C. To minimize the bleeding risk, we replaced factor VIII intravenously in accordance with the World Federation of Hemophilia guidelines for minor surgery. FVIII (3,000 IU) was administered 15 minutes before BTX injection. One day later, 2,000 IU was administered, and 2 days later, another 2,000 IU was administered. We performed the real-time Ultrasound-guided BTX injection three times, then spasticity and upper extremity function improved without adverse events. BTX injection can be considered as a treatment option for spasticity among patients with hemophilia.
