单脐动脉在产前超声诊断中的意义

目的：探讨单脐动脉在产前超声诊断胎儿畸形及胎儿生长受限的意义。方法：回顾性分析太原市太航医院超声室2008年9月至2012年6月常规产前超声检查的7890例中36例单脐动脉孕妇的临床资料，分析单脐动脉胎儿合并结构畸形及生长受限的情况。结果：36例单脐动脉中，合并结构畸形的11例，生长受限的3例，单纯单脐动脉22例，出生后随访未见畸形。结论：单脐动脉合并胎儿结构畸形及生长受限的风险明显高于正常脐动脉的胎儿，发现单脐动脉的胎儿，应进行各个部位系统的产前检查，以降低胎儿出生缺陷的发生。

The Diagnosis Significance of Single Umbilical Artery in Prenatal Ultrasound

Objective： fetal malformations and fetal To investigate the diagnosis significance of growth restriction. Methods： The clinical single umbilical artery in prenatal ultrasound of data of 36 cases with single umbilical artery of 7890 for routine prenatal ultrasound were retrospectively analysed in the hospital from September 2008 to June 2012 and so was the 36 patients with single umbilical artery combined with fetal congenital structural abnormality and growth re- striction. Results： Of 36 patients with single umbilical artery, there were 11 cases of malformation of the merged structure, growth restriction of 3 cases and there were 22 cases of simple single umbilical artery with no deformity follow-up after birth. Conclusion： The risk of suffering from single umbilical artery merger fetal malformations and growth restriction is significantly higher than the normal umbilical artery of the fetus. As a result, once a single umbilical artery fetal prenatal is checked, to reduce birth defects, it is essential that all parts of the system should be examined.
