Ultrasound diagnosed upper limb reduction in a fetus at 17 weeks gestation. Post-termination necropsy confirmed the limb defect, prompting discussion on amniotic band syndrome.

Area of Science:

  • Medical Genetics
  • Prenatal Diagnosis
  • Developmental Biology

Background:

  • Chorionic villus sampling (CVS) is a common first-trimester prenatal diagnostic test.
  • Genetic and environmental factors can influence fetal development, leading to congenital anomalies.
  • Upper limb reduction defects encompass a spectrum of conditions affecting limb formation.

Observation:

  • A 17-week ultrasound revealed upper limb reduction.
  • Chorionic villus sampling was performed at 9 weeks' gestation.
  • The fetus was otherwise anatomically normal upon examination.

Findings:

  • Prenatal diagnosis of upper limb reduction was confirmed via ultrasound.
  • Necropsy following pregnancy termination verified the limb malformation.

  • The study explores the potential link between limb reduction and amniotic band syndrome.

    • Implications:

    • Early and accurate prenatal diagnosis of limb defects is crucial for informed decision-making.
    • Understanding the etiology of limb reduction, such as amniotic band syndrome, aids in genetic counseling.
    • This case highlights the importance of integrating imaging and post-mortem examinations in evaluating congenital anomalies.
