Second trimester fetal growth restriction (FGR) affects 2.8% of fetuses. Abnormal karyotypes or malformations are present in 15% of FGR cases, influencing prenatal management.
Area of Science:
- Perinatology
- Prenatal Diagnosis
- Fetal Medicine
Background:
- Second-trimester fetal growth restriction (FGR) is a significant concern in prenatal care.
- Identifying associated chromosomal abnormalities and fetal defects is crucial for accurate diagnosis and management.
Purpose of the Study:
- To determine the incidence of chromosomal abnormalities, syndromic associations, and fetal defects in second-trimester FGR.
- To analyze factors influencing prenatal management and counseling for FGR.
Main Methods:
- Retrospective review of 239 fetuses with FGR (abdominal circumference <5th percentile) between 14-27 weeks gestation.
- Exclusion of multiple pregnancies.
- Analysis of medical records for malformations, aneuploidy, and pregnancy outcomes.
Main Results:
- FGR was identified in 2.8% of 8626 fetuses.
- 15% of FGR cases had abnormal karyotypes or syndromic associations, with Trisomy 18 being the most common (4.2%).
- 28% had morphological abnormalities without aneuploidy; common defects included short femur, omphalocele, and gastroschisis.
Conclusions:
- The study highlights the spectrum of abnormalities associated with second-trimester FGR.
- Absence of malformations, degree of growth restriction, maternal age, and amniotic fluid index are key factors for prenatal counseling.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
