ULTRASOUND OF FETAL ASCITES

Fetal ascites is defined as a rim of fluid in the fetal peritoneal cavity, at least partly surrounding the liver and the fetal bladder.

• The sonolucent areas can be demonstrated surrounding loops of bowel or outlining the intra-abdominal portion of the umbilical vein.
• AS the amount of fluid increases, the abdomen will enlarge, and the falciform ligament and umbilical vein will straighten out.
• The liver appears suspended.
• In severe cases, small bowel will float freely in the ascitic fluid and the omental sac may become visible.
