概述

 单脐动脉(single umbilical artery,SUA)是指胎儿先天性缺乏一条脐动脉,是脐带异常中最常见的一种,其中左侧缺失约占70%,右侧缺失约占30%。发生原因可能有以下3种:(1)已经出现的脐动脉中的一条发育不全;(2)先前正常的脐动脉萎缩或闭锁;(3)尿囊总动脉或脐总动脉的持续存在。 类型 单纯性:是指仅存在单脐动脉,胎儿未发现其它结构的异常,按期产检,一般来说胎儿预后好。 多发畸形:如果彩超提示胎儿有畸形,很少是单一的,几乎均是多

Single umbilical artery is associated to congenital malformations in most organ systems, but the pattern has not been consistent. Genetic and persisting environmental factors have been suggested to influence the development of single umbilical artery, but if there is an increased risk of single umbilical artery in a subsequent pregnancy of the same woman is not known. Whether there is an effect of the sex of the fetus on the risk of single umbilical artery and associated malformations is unclear. Most studies of single umbilical artery and malformations are based on pathology reports or hospital based series which may be affected by selection bias, warranting population-based studies.

译文

单个脐动脉与大多数器官系统中的先天性畸形有关,但该模式并不一致。 已经提出遗传和持续存在的环境因素影响单个脐动脉的发展,但是如果在同一个女性的后续怀孕中单个脐动脉的风险增加则是未知的。 是否存在胎儿性别对单个脐动脉和相关畸形的风险的影响尚不清楚。 大多数单脐动脉和畸形的研究是基于病理报告或基于医院的系列,可能受选择偏倚影响,需要进行基于人群的研究。
