Background: Fetal brain development is a complicated process that continues throughout pregnancy. Fetal sulcus development has typical morphological features. Assessment of fetal sulcus development to understand the cortical maturation and development by prenatal ultrasound has become widespread.

Methods: This retrospective study assessed the feasibility of first-trimester echocardiography in detecting absence of the aortic valve. All cases of absence of the aortic valve diagnosed by first-trimester fetal echocardiography from January 2010 to December 2014 were identified at a single referral center using an established perinatal database.
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.
