Absent ductus venosus (ADV) is a rare vascular anomaly. We describe a fetus/neonate with ADV with a partial liver defect. A 41-year-old woman was referred to our institute because of fetal cardiomegaly detected by routine prenatal ultrasound, which revealed absence of ductus venosus with an umbilical vein directly draining into the right atrium, consistent with extrahepatic drainage type of ADV. She vaginally gave birth to a 3,096-gram male infant at 38 weeks of gestation. Detailed ultrasound examination revealed a defect of the hepatic rectangular leaf at half a month postnatally. He showed normal development at 1.5 years of age with the liver abnormality and a Morgagni hernia. Liver morphological abnormality should also be considered as a complication of ADV.
静脉导管缺如（ADV）是一种罕见的血管异常。我们描述了一名患有ADV并伴有部分肝脏缺损的胎儿/新生儿。一名41岁女性因常规产前超声检查发现胎儿心脏肥大而转诊至我院，超声显示静脉导管缺如，脐静脉直接汇入右心房，符合肝外引流型ADV。她在妊娠38周时经阴道分娩出一名体重3096克的男婴。产后半月的详细超声检查显示肝方叶缺损。他1.5岁时发育正常，但存在肝脏异常和 Morgagni 疝。肝脏形态异常也应被视为ADV的一种并发症。
