Despite the utility of prosthetic silo reduction techniques, surgical treatment of giant omphaloceles containing herniated liver may result in acute compromise of hepatic vascular flow. The authors report a case of an infant with a giant omphalocele containing liver, in whom hepatic vascular compromise was suspected during the course of prosthetic visceral reduction. Doppler ultrasonography performed on the herniated liver through the prosthetic silo demonstrated triphasic vascular flow in the liver as well as normal hepatic venous flow and vena caval flow, and permitted continued gradual visceral reduction and a safe, delayed primary abdominal wall closure on the seventh day of life. Doppler ultrasonography performed through the silo may be an important diagnostic adjunct during the visceral reduction phase of staged abdominal wall closure in infants with giant omphaloceles.
