Although stroke risk during pregnancy appears to be low, morbidity and mortality rates are high among pregnant women who do have strokes. A population-based study estimated that there are just 1.5 cases of antenatal stroke per 100,000 women delivering. However, use of pharmacologic, surgical, and organized stroke unit care varied widely among study participants. The case-fatality rates were 20% for all strokes and 50% for hemorrhagic strokes.
