彩色多普勒超声产前诊断胎儿单脐动脉的价值

目的探讨彩色多普勒超声产前诊断胎儿单脐动脉的价值。方法应用常规产前彩色超声检查,发现胎儿异常者仔细检查脐血管,发现单脐动脉者仔细检查是否合并胎儿畸形,同时估测胎儿大小,并判断其与孕周是否相符,并测量脐动脉的血流速度及S/D比值。结果 2006年至2010年来我院行彩色多普勒超声检查诊断为单脐动脉者31例,其中15例合并其他结构畸形,9例脐动脉血流参数异常,6例胎儿大小明显小于孕周,31例单脐动脉及其伴发畸形,均经引产或正常产证实。结论彩色多普勒超声诊断单脐动脉准确性和特异性高,超声检查发现胎儿单脐动脉时需多角度动态观察以明确是否合并其他器官的发育畸形,对于继续妊娠者需密切注意胎儿发育情况和产程,单脐动脉与先天畸形遗传疾病等密切相关,产前超声检查单脐动脉对降低围生期病死率提高胎儿生存质量具有重要意义。

The Value of the Color Doppler Ultrasound Prenatal Diagnosing Fetal Single Umbilical Artery

Objective To evaluate the value of the Color Doppler Ultrasound prenatal diagnosing fetal single umbilical artery. Methods To application of routine prenatal diagnosis scanning the fetus with abnormal umbilical. Then scan the fetal malfgr/nation and the fetal size when the fetus with single umbilical artery. To measurement the blood flow velocity of umbilical artery and S/D. To determine the consistent with the gestational age and the fetal size. Results The 31 cases of single umbilical artery in our hospital, the 15 cases with other malformations, the 9 cases with abnormal blood flow parameters of umbilical artery, the 6 cases which the fetal size is smaller than gestational age. The 31 cases are confirmed by the induction of labor. Conclusion The Color Doppler Ultrasound has high accuracy and specificity prenatal diagnosing fetal single umbilical artery. Single umbilical artery is closely related with congenital malformations and other genetic diseases. Prenatal ultrasonography is important to reduce perinatal mortality rate and to improve the quality of life of the fetus for fetal single umbilical artery.
