Abstract
Preeclampsia (PE) is a multisystem disorder, usually defined as the development of hypertension and proteinuria after 20 weeks of pregnancy. The sFlt-1/PlGF ratio has been widely studied as a diagnostic and prognostic marker of preeclampsia and other manifestations of placental dysfunction. A sFlt-1/PlGF ratio greater than 85 for early PE, <34 weeks of gestation suggests a high risk of PE requiring close clinical monitoring. Our main aim was to evaluate the maternal and perinatal outcomes of pregnancies with an extremely high sFlt-1/PlGF ratio. The analysis included data on placental growth factor and soluble fms-like tyrosine kinase serum levels, measured during 2017–2020 in 128 pregnant women. Here we present 8 cases of women with a numerical ratio greater than 850. In all 100% of cases, the signs of obstetric angiogenic catastrophe requiring imminent delivery developed soon. We observed a trend for worsening perinatal outcomes in women with an extremely high sFlt-1/PlGF of ≥850.
