Second Place Winner of the W. Frederick Sample Student Literature Review AwardUltrasound is an important tool in the evaluation of fetal development and detection of fetal abnormalities. The ability to detect abnormalities in utero can help improve perinatal care; therefore, a detailed sonographic examination of the fetus should always be obtained. Abdominal wall defects that can be recognized by sonography include omphalocele, gastroschisis, umbilical cord hernia, and limb/body wall complex. The sonographer should attempt to give a detailed description of the defect including the organs involved, the presence of a sac, the site of cord insertion, and the presence of any associated anomalies. This information can aid the physician and parents in determining the course of management of the pregnancy.Ultrasonography has become a valuable tool in the evaluation of fetal development. Detection of fetal anomalies in utero has played an important role in improving perinatal care.Defects of the abdominal wall are easily identified by sonography. These defects include omphalocele, gastroschisis, umbilical cord hernia, and limb/body wall complex.When an abdominal wall defect is discovered it is important for the sonographer to make a thorough search for any associated anomalies. Omphalocele, umbilical cord hernia, and limb/body wall complex are usually associated with more severe anomalies than is gastroschisis. The sonographer should attempt to give a detailed description of the defect including the organs involved, the presence of a sac, and the site of cord insertion.The prenatal determination of the type of abdominal wall defect and the presence of any associated anomalies is important. This information can be used by the physician to aid in determining the course and management of the pregnancy.' OMPHALOCELE Omphalocele is a midline abdominal wall defect. It is defined as a dilated umbilical ring containing umbilical vessels and herniated abdominal viscera.
