Clinical Characteristics and Prognostic Factors in Hemophiliacs with Intracranial Hemorrhage: A Single-Center, Retrospective Experience.

Intracranial hemorrhage (ICH) is the most serious bleeding event that occurs in patients with hemophilia; its estimated mortality rate is approximately 20 %, accounting for the largest number of deaths from bleeding. We conducted this single-center, retrospective study to examine the characteristics of and prognostic factors in patients with hemophilia. A comprehensive review of 12 cases of intracranial hemorrhage (ICH) among 10 patients. All 12 cases of ICH in the 10 patients were treated with clotting factor concentrates. Three patients had intracerebral hemorrhage that required neurosurgical intervention. After presenting with ICH, two pediatric patients developed antibodies to clotting factors. Two adult patients with intracerebral hemorrhage died, and the mortality rate was thus 20.0 % (2/10) in our clinical series. Prompt and intensive treatment with clotting factor concentrates may significantly lower the mortality rate among patients with hemophilia presenting with ICH. Our results showed a better prognosis in pediatric patients with intracerebral hemorrhage. Clinicians should pay special attention to the possible development of inhibitors after intensive treatment in pediatric patients. Further studies are needed to examine methods for administering clotting factor concentrates and to determine whether neurosurgical intervention is essential in each case.
