Fatal Stroke in Pregnancy and the Puerperium

Abstract

Background and Purpose— Fatal stroke during pregnancy and the puerperium is rare. Pregnancy-related hypertension and vascular abnormalities underlie significant proportions of pregnancy-related stroke, but up to one-quarter are of no known cause. Methods— Case series of fatal pregnancy-related stroke. All cases where the cause of death was attributed to stroke during pregnancy/postpartum were retrieved from the National Coronial Information System database (January 1, 2009 to December 31, 2016). Results— Fourteen fatal strokes were identified, all hemorrhagic in origin. Underlying causes included pregnancy-related hypertension, rupture of vascular malformations, vasculitis, and cardiomyopathy. Conclusions— Fatal pregnancy-related stroke occurred secondary to hemorrhages of heterogeneous causes, including pregnancy-related hypertension and previously undiagnosed risk factors.
