A case is described in which it was found at autopsy that the umbilical cord of a macerated stillborn infant had four patent vessels (two arteries and two veins) throughout its length. This was due to a rare persistence of the caudal portion of the right umbilical vein. The infant had multiple congenital anomalies including complete thoracic ectopia cordis, a symmetrical bifid liver, severe bilateral cleft lip and palate with absent soft palate and uvula , and cecum mobile. The autopsy findings are detailed and the relevant literature and embryology briefly discussed.
描述了一例病例，在尸检时发现一名浸软死产婴儿的脐带全程有四条开放血管（两条动脉和两条静脉）。这是由于右脐静脉尾部罕见的持续存在所致。该婴儿有多种先天性异常，包括完全性胸外心脏异位、对称的双叶肝脏、严重的双侧唇腭裂伴软腭和悬雍垂缺如以及游动盲肠。详细介绍了尸检结果，并简要讨论了相关文献和胚胎学。
