Catastrophic antiphospholipid syndrome during pregnancy.

Catastrophic antiphospholipid syndrome (CAPS) is an uncommon and the most severe form of antiphospholipid syndrome (APS). A 33-week pregnant patient with Klippel-Trenaunay syndrome, past SARS-CoV-2 infection and type I fetal growth restriction with shortening of the fetal long bone was diagnosed in our center with a probable CAPS. Cesarean section was performed four days after the diagnosis due to the torpid evolution of the patient.

A contingent model for cell-free DNA testing to detect fetal aneuploidy after first trimester combined screening.

Objective: To assess the results of the first trimester combined test to design a prenatal protocol for the introduction of the cell-free fetal DNA test as a contingent screening model.

Method: An observational retrospective study in 12,327 singleton pregnancies to analyze the results of the combined first trimester screening, the nuchal translucency ≥97.5 percentile, their cytogenetic results and birth outcomes.
