ABSTRACT
Prothrombotic disorders are believed to be important contributors to the etiology
of peri- and neonatal arterial ischemic stroke and sinovenous thrombosis, which may
lead to life-long disability. This article reviews hematological issues unique to
the perinatal period, including: the significance of the placenta as the interface
between maternal and fetal circulations; normal changes in the coagulation system
of mothers during and just after gestation; and the significance of prothrombotic
disorders in the mother and/or fetus. Other possible maternal and neonatal contributors
to peri- and neonatal stroke are discussed, including: infection, pre-eclampsia, diabetes,
and drug use in the mother; and infection, dehydration, complex congenital heart disease,
extracorporeal membrane oxygenation, and catheter placement in the neonate. Possible
approaches to preventing and treating perinatal and neonatal stroke are presented.
