Abstract
Complex developmental changes occur during embryonic life as the vitelline veins evolve into the portal vein. Duplication of the portal vein is an uncommon anomaly. Complications of this anomaly include variceal bleeding, portal hypertension and duodenal obstruction. We report a case of this uncommon anomaly and present an embryological perspective as to the cause for this abnormal configuration of the portal veins.
摘要
在胚胎期，随着卵黄静脉演变成门静脉，会发生复杂的发育变化。门静脉重复是一种罕见的异常情况。这种异常的并发症包括静脉曲张出血、门静脉高压和十二指肠梗阻。我们报告了一例这种罕见的异常情况，并从胚胎学角度阐述了门静脉这种异常形态的成因。
