Abdominal wall and umbilical cord anomalies

Area of Science:

• Developmental biology
• Medical embryology
• Prenatal diagnosis

Background:

• The anterior abdominal wall and umbilical cord develop during early human embryogenesis.
• Congenital anomalies can arise from disruptions in this complex developmental process.
• Understanding embryologic origins is crucial for diagnosing and managing these conditions.

Purpose of the Study:

• To present the embryology of the anterior abdominal wall and umbilical cord.
• To detail abnormal embryology and associated anomalies.
• To describe prenatal diagnostic techniques for these abnormalities.

Main Methods:

• Review of embryologic development of the anterior abdominal wall and umbilical cord.
• Tabular presentation of abnormal embryology and resulting anomalies.
• Chronological review of anomalies based on embryologic development.
• Description of prenatal diagnostic methods.

Main Results:

• Detailed presentation of normal embryology for context.
• Comprehensive catalog of anomalies linked to specific embryologic events.
• Explanation of how timing of developmental errors influences anomaly presentation.
• Overview of imaging and diagnostic modalities used prenatally.

Conclusions:

• Embryologic understanding provides a framework for classifying and diagnosing abdominal wall and umbilical cord defects.
• Prenatal diagnosis relies on recognizing deviations from normal embryologic development.
• Knowledge of embryogenesis aids in predicting and managing congenital anomalies.
