Fetal ultrasound

The umbilical cord

The arrow in the image below points to the site where the umbilical cord is attached to the fetus's belly, also called the abdomen. By looking at this area, the health care team can check for several conditions. They include a condition called omphalocele. It happens when contents of the abdomen come out through an opening at the bellybutton. Another condition is gastroschisis. It involves a break or split in the tissue that forms the abdominal wall.
