Embolization for Refractory Subacute Subdural Hematoma in a Child with Severe Hemophilia Type A.

Hemophilia is an X-linked hemorrhagic disease due to coagulation factor VIII or IX deficiency with approximately 5-10% incidence of central nervous system bleeding. We present an intriguing case of a refractory subacute subdural hematoma (SDH) controlled with endovascular embolization in a hemophilic patient. A 5-year-old severe hemophilic A boy presented with a life threatening left parietal subcortical hemorrhage, for which he underwent craniotomy and evacuation of the hematoma. Recurrent hemorrhage necessitated a repeat craniotomy. This was followed by three episodes of SDH development at the craniotomy site that were treated surgically, and finally controlled with embolization in the subacute period. This case presents a novel option for treating a refractory SDH in patients with coagulation disorders.
