The appearance of polyhydramnios and dilated bowel loops on prenatal sonographic examination usually implies mechanical obstruction. The prognosis is variable, depending on the etiology. Congenital pseudo-obstruction, a potentially lethal disease, comprises a group of disorders characterized by intestinal obstruction in the absence of an anatomic lesion. This report focuses on the prenatal diagnosis of intestinal pseudo-obstruction, and two cases of transient congenital intestinal pseudo-obstruction in one family are described. In both, the prenatal sonographic presentation was of small bowel obstruction. In one case there was postnatal suspicion of neurogenic bladder, and in the other there was unilateral hydronephrosis. The sonographic appearance of intestinal pseudo-obstruction is similar to that of mechanical obstruction. The clues to the prenatal diagnosis of pseudo-obstruction include associated urinary tract abnormalities and a family history of pseudo-obstruction.
产前超声检查发现羊水过多和肠袢扩张通常提示机械性梗阻。预后因病因而异。先天性假性肠梗阻是一种潜在致命性疾病，包括一组在无解剖学病变情况下以肠梗阻为特征的疾病。本报告重点关注肠道假性肠梗阻的产前诊断，并描述了一个家族中的两例短暂性先天性肠道假性肠梗阻病例。两例患者产前超声均表现为小肠梗阻。其中一例产后怀疑有神经源性膀胱，另一例有单侧肾积水。肠道假性肠梗阻的超声表现与机械性梗阻相似。假性肠梗阻产前诊断的线索包括相关的泌尿系统异常和假性肠梗阻家族史。
