The prenatal sonographic findings in 10 infants with omphalocele or gastroschisis diagnosed either by sonogram or by physical examination at birth are reviewed. There were six true-positive diagnoses, as well as two false-positive and two false-negative diagnoses by sonography. The false-positive cases resulted from confusion of umbilical cord with extruded bowel (1 case) and oligohydramnios coupled with improper scanning technique (1 case). The false-negative cases resulted from poor documentation of fetal anatomy (1 case) and confusion of extruded bowel with umbilical cord (1 case). These pitfalls may be avoided by using optimal scanning technique with documentation of fetal anatomy and pulsed Doppler sonography.
回顾了10例经超声检查或出生时体格检查诊断为脐膨出或腹裂的婴儿的产前超声检查结果。超声检查有6例假阳性诊断、2例假阴性诊断。假阳性病例分别是脐带与突出肠管混淆（1例）以及羊水过少合并扫描技术不当（1例）。假阴性病例分别是胎儿解剖结构记录不佳（1例）以及突出肠管与脐带混淆（1例）。通过使用记录胎儿解剖结构的最佳扫描技术和脉冲多普勒超声检查可避免这些陷阱。
