Chromosome mosaicism of the placenta--a cause of developmental failure of the fetus?

abstract：OBJECTIVE:We aimed to study the role of placental pathology in the prediction of preeclampsia (PE) recurrence. METHODS:The medical records and pathological placental reports of all women diagnosed with PE, during 2008-2015, were reviewed. The study population was divided according to the outcome of their subsequent pr...
