Objective: We aim to determine the accuracy of first-trimester ultrasonography in detecting fetal limb abnormalities.
Methods: This is a retrospective study of all women undergoing fetal nuchal translucency (NT) assessment and detailed fetal anatomic survey in the first trimester at a single tertiary-care referral center in China. Fetal anatomy scans were repeated in the second trimester.
Article Synopsis
- The study aimed to examine the frequency, prenatal diagnosis, and outcomes of congenital dacryocystocele in fetuses through ultrasound analysis.
- It found that the incidence was low (0.016%), with a higher occurrence in females, and most cases were unilateral lesions; cyst size correlated with gestational age.
- Most cases resolved on their own before or shortly after birth, suggesting that congenital dacryocystocele should be viewed as a developmental variant rather than a serious birth defect.
Objective: To establish the normal reference ranges of transabdominal ultrasound measurements of the posterior fossa structure in fetuses at 11 to 13⁺⁶ gestational weeks and explore their clinical value in screening open spina bifida (OSB).
Methods: Between January, 2013 and September, 541 randomly selected normal fetuses underwent nuchal translucency at the gestational age 11 to 13⁺⁶ weeks. The parameters of the posterior fossa were measured in mid-sagittal view of the fetal face and the axial view of the transverse cerebellum insonated through the anterior fontanel by transabdominal ultrasound to establish the normal reference ranges.
