The birth of an infant with increased number of umbilical veins is a rare event and has been previously reported to be associated with a high incidence of major congenital anomalies. This report documents a normal infant with two umbilical veins resulting in a four vessel cord. A male infant (third of triplet pregnancy resulting from multiple zygote implantation) was born at 30 weeks' gestation weighing 1320 g.Two umbilical veins and two umbilical arteries were noted on cannulation and X ray. Physical examination and cranial, abdominal, and cardiac ultrasound exam were normal. One-year follow-up was normal. The birth of infant with a four-vessel cord mandates comprehensive workup for associated anomalies but this case indicates that such a finding is not always ominous.
出生时伴有脐静脉数量增多的婴儿是罕见事件，此前有报道称其与重大先天性畸形的高发生率相关。本报告记录了一名具有两条脐静脉从而形成四血管脐带的正常婴儿。一名男婴（多合子着床导致的三胞胎妊娠中的第三个）在孕30周时出生，体重1320克。插管和X线检查时发现两条脐静脉和两条脐动脉。体格检查以及头颅、腹部和心脏超声检查均正常。一年随访结果正常。四血管脐带婴儿的出生需要针对相关畸形进行全面检查，但该病例表明这一发现并不总是预示着不祥。
