Posterior Reversible Encephalopathy Syndrome Following Eclampsia: Assessment of Clinical and Pregnancy Characteristics

( Am J Obstet Gynecol . 2024;231(1):e19–e25. doi: 10.1016/j.ajog.2024.02.298) Posterior reversible encephalopathy syndrome (PRES) is an acute neurological condition that presents with varying symptoms such as visual defects, headaches, seizures, and/or altered consciousness. It is a rare complication during pregnancy, particularly linked to eclampsia. Studies suggest that PRES occurs in up to 90% of pregnant women with eclampsia. However, the clinical characteristics of these patients, particularly in large population-scale studies, have not been well-explored. This study, presented in a research letter, aims to examine the clinical features and maternal morbidity of PRES following eclampsia at the national level in the United States.
