Autopsy Findings of Central Nervous System Anomalies in Intact Fetuses Following Termination of Pregnancy After Prenatal Ultrasound Diagnosis.

Objectives: Central nervous system (CNS) anomalies are the second most frequent category of congenital anomalies after congenital heart defects (CHDs). In this study, the aim was to investigate the distribution of different CNS anomalies with associated anomalies and karyotype in a fetal autopsy population of terminated pregnancies over a 30-year period and to correlate the ultrasonographic diagnoses of CNS anomalies with autopsy findings.

Materials And Methods: This study includes 420 intact fetuses with CNS anomalies terminated at gestational ages 11 to 33 over a 30-year period from 1985 to 2014.

Variability Over Time of Normal-Sized Fetal Renal Pelvis During the Second Trimester Scan.

Purpose: To investigate the variability of the normal-sized fetal renal pelvis (≤5 mm) over time and to analyze repeatability of measurements.

Materials And Methods: 98 fetal renal pelvises and 49 fetal urinary bladders were analyzed at a gestational age of 17-20 weeks at St. Olavs Hospital, Trondheim, Norway.

Detection of structural abnormalities in the first trimester using ultrasound.

During the past 25 years, embryonic and early fetal ultrasound and diagnosis have increasingly gained attention in pregnancy care. Modern high-frequency ultrasound transducers make it possible to obtain detailed images of the early conceptus and its organs, and thus move part of the anatomy and anomaly scan from the second to the first trimester. Today, detection of embryonic and fetal structural abnormalities in the first trimester has frequently been reported.
