Description

The authors present here a case of congenital abdominal wall defect associated with vitelline vascular remnant. It suggests a hint to embryogenesis of gastroschisis. A new-born male, weiging 3,000g, was transferred to the authors' hospital because of abdominal wall defect (gastroschisis). On operation, the abdominal wall defect was 28mm in diameter. The umbilical cord attached normally on the left margin of the defect, and an abnormal string was found between eviscerated ileal mesentery and the right margin of the defect. The string was diagnosed as vitelline vascular remnant by its histological findings and its connecting position. The authors concluded that the abdominal wall defect occurred in the umbilical cord itself, because the vitelline artery and vein had to attach the umbilical cord. This suggests that gastroschisis is probably a result of umbilical cord rupture in the uterin.
