Renal vascularization indexes and fetal hemodynamics in fetuses with growth restriction.

Objective: To identify the correlation between the renal vascularization index (VI), the flow index (FI) and the vascularization and flow index (VFI) and placental and fetal hemodynamics in fetuses with growth restriction.

Method: Bidimensional ultrasound and three-dimensional power Doppler with the VOCAL technique were used to determine the renal vascular indexes and fetal and placental hemodynamics in fetuses below the 10th percentile for fetal weight. Partial correlation analysis (controlled for renal depth and gestational age) was performed.

Fetal thrombotic vasculopathy: A case report and literature review.

Introduction:: Fetal thrombotic vasculopathy is a recently described placental alteration with varying degrees of involvement and often associated with adverse perinatal outcomes. The diagnosis is made histologically and therefore is postnatal, which makes it a challenge in clinical practice.

Method:: Case report and review of literature on the subject.

Predicting pH at birth in pregnancies with abnormal pulsatility index and positive end-diastolic velocity in the umbilical artery.

Objectives: To identify potential associations between fetal surveillance tests and acidosis at birth in pregnancies with abnormal but positive end-diastolic velocity in the umbilical artery.

Methods: A prospective case-control study [group 1: pH < 7.2; group 2: pH ≥ 7.
