Vitelline duct anomalies (VDA) are rare complications of persistent omphalomesentric duct or vitelline duct connecting the developing embryo with the yolk sac. VDA can be asymptomatic (detected incidentally) or symptomatic, most common of which is Meckel's diverticulum. A patent vitelline duct is the. most common symptomatic presentation in African children and we present here a four day old neonate with patent vitelline duct with ileal prolapse. The neonate was operated with the patent vitelline duct and gangrenous ileum resected and end to end ileal anastomosis done.
卵黄管异常（VDA）是持续存在的卵黄管或脐肠系膜管连接发育中的胚胎与卵黄囊的罕见并发症。VDA可以无症状（偶然发现）或有症状，其中最常见的是梅克尔憩室。卵黄管未闭是非洲儿童最常见的有症状表现，我们在此报告一名4天大的患有卵黄管未闭并伴有回肠脱垂的新生儿。该新生儿接受了手术，切除了未闭的卵黄管和坏死的回肠，并进行了回肠端端吻合术。
