Splenic Artery Embolization in a Patient With Intracranial Hemorrhage Due to Refractory Persistent Immune Thrombocytopenia

Background:Managing intracranial bleeding in patients with refractory immune thrombocytopenia is difficult.Observation:A 16-year-old female refractory to prednisolone, intravenous immunoglobulin, eltrombopag, and cyclosporin exhibited heavy menstrual bleeding requiring packed red blood cell transfusions. Autoimmune antibodies were detected, indicating of lupus, and hydroxychloroquine sulfate was administered. In month 6 following the diagnosis, the patient presented with intracranial hemorrhage. Splenic artery embolization promptly increased platelets, and the patient was discharged without any neurological sequela. In month 5 of embolization, the patient's platelet count continued to exceed 300,000/mu L without any medical treatment.Conclusions:Splenic artery embolization is a life-saving procedure in refractory immune thrombocytopenia.
