Favorable neurological outcome in 7 cases of perinatal intracranial hemorrhage due to immune thrombocytopenia.

Overview

Neonatal intracranial hemorrhage secondary to immune thrombocytopenia has been uniformly associated with neurological sequelae in survivors. These sequelae are seizures, hydrocephalus, mental retardation, and developmental delay. We report 7 survivors of intracranial hemorrhage who were prospectively evaluated regarding their long-term outcome at a mean of approximately 5 years of age. Five children were completely normal. One was delayed in speech, and one had a ventriculoperitoneal (VP) shunt in place and a residual hemiparesis. Four children had had seizures including the two with sequelae (speech delay and hemiparesis); only the patient with the VP shunt was still taking anticonvulsant medication. This latter patient was also the only one who required special education classes in which she was maintaining her grade level. In summary, a good long-term outcome can be expected in at least some patients with neonatal intracranial hemorrhage in cases of severe neonatal thrombocytopenia caused by maternal antiplatelet antibodies. This good outcome may be a result of, and should encourage, early diagnosis and vigorous supportive care in the neonatal intensive care unit.
