Neonatal venous sinus thrombosis is a well-recognized, but infrequently dia
gnosed, cause of neonatal encephalopathy. Previous reports have tended to o
mit reference to the importance of maternal factors in predisposing the inf
ant to this condition. This report, in which eight patients with neonatal v
enous sinus thrombosis are presented, will reveal a strong association betw
een pre-eclampsia, prothrombotic disorders, and neonatal venous sinus throm
bosis. Contrary to previously published reports, there is a high likelihood
of neurodevelopmental residua after this condition. (C) 2001 by Elsevier S
