胎儿单脐动脉的超声诊断及伴随胎儿畸形的临床研究

目的探讨胎儿单脐动脉产前超声声像图特征及伴随胎儿畸形的临床价值，旨在尽早干预以减少缺陷儿的出生。方法回顾性分析2008年6月～2011年5月在我院产前超声发现62例胎儿单脐动脉的形态结构、血流信号特征及伴随胎儿畸形，并与产后结果及病理学检查对照。结果62例超声图像均诊断为胎儿单脐动脉，其中47例（75．8％）产前超声未发现异常，15例中合并单发畸形或异常6例（9．7％），合并多发畸形9例（14．5％）。产后检查脐带数目及病理对照。准确率100％。47例单纯性SUA胎儿出生后随访，发现1例多指，1例小耳畸形，胎儿畸形诊断率96．77％。结论单脐动脉胎儿与伴随畸形密切相关，单纯性单脐动脉胎儿需密切随访。

Ultrasound diagnosis of fetal umbilical artery and accompanying fetal malformation

Objective To investigate the fetal single umbilical artery prenatal ultrasound sonographic features and ac- companied by the fetal malformations clinical value, aimed at early intervention to reduce defects in children born. Methods A retrospective analysis found 62 cases of fetal umbilical artery morphology from June 2008 to May 2011 in our hospital prenatal ultrasound blood flow signal characteristics associated with fetal malformations and control post- partum findings and pathological examination. Results The 62 cases of ultrasound diagnosis of fetal umbilical artery in 47 cases（75.8%） no abnormal prenatal ultrasound, 15 cases combined single malformation or abnormal 6 cases（9.7%） combined with multiple deformities in 9 cases （14.5%）. The postpartum check umbilical cord number and pathology, the accuracy rate of 100%. Follow-up, 47 cases of simple SUA birth found one case of multi-finger,one case of small ear malformations, fetal malformation diagnosis rate of 96.77%. Conclusion The single umbilical artery fetus and ac- companied by malformations closely related, simple single umbilical artery fetus need close follow-up.
