title: Stroke and pregnancy.
abstract: OBJECTIVE
  To study the controversial relationship between pregnancy and stroke. Old studies and those from developing countries suggest that pregnancy considerably increases the risk of stroke.
  
  
  METHODS
  The records of 946 consecutive cases of stroke observed in Saudi patients in 10 years were reviewed. Cases which occurred during pregnancy or during the first 15 days postpartum were included in the study.
  
  
  RESULTS
  Twelve patients (1.3%) were pregnant or in postpartum at stroke onset. They constituted 27% of women of childbearing age. Cerebral infarction was diagnosed in nine cases and cerebral hemorrhage in three. Four patients died.
  
  
  CONCLUSIONS
  The risk of stroke is only marginally increased (x 1.5) in pregnant compared with non-pregnant Saudi women. Many factors including peripartum cardiomyopathy, patent foramen ovale, changes in clotting factors, peripartum angiopathy and vasoactive steroid hormones, could be responsible for this increased risk.
