The management of cryptogenic stroke in pregnancy

Abstract

Cerebrovascular accidents (CVAs) during pregnancy are uncommon but can have devastating consequences. The causes of CVA in both the pregnant and the non-pregnant state are diverse and require thorough investigation. Recent studies have indicated that embolic stroke in young adults may be caused by paradoxical emboli through a patent foramen ovale (PFO), suggesting that the presence of a PFO should be specifically sought in pregnant or postpartum women presenting with CVA. This review will outline the causes of CVAs in pregnancy and the role of paradoxical emboli, with a focus on PFO.
