This chapter describes cerebrovascular accidents in pregnancy. Stroke, the sudden onset of brain dysfunction from a vascular cause, is one of the most common causes of long-term disability. Although rare during childbearing years, stroke is even more devastating when it occurs in a young woman trying to start a family. Pregnancy and the postpartum period are associated with an increased risk of ischemic stroke and intracerebral hemorrhage, although the incidence estimates have varied. Recent studies suggest that the risk of cerebral infarction is increased during the puerperium but not during pregnancy itself. Most of the known causes of ischemic stroke in the young have been reported during pregnancy. This chapter covers the possibility and risk factors, etiology, diagnostic work-up, signs and symptoms of stroke, causes of cardiovascular accident (CVA), and prevention of CVA.
