摘要:: 目的:探讨速度向量成像技术在妊娠期糖尿病胎儿左心室功能评价中的临床应用价值。方法:采集54例妊娠期糖尿病胎儿和54例正常对照组胎儿动态标准四腔心切面，应用速度向量成像技术脱机分析室间隔及左室侧壁共6个节段的速度、应变、应变率来反映胎儿左心室的收缩及舒张功能。结果:妊娠期糖尿病组胎儿收缩期峰值速度(Vs)和舒张期峰值速度(Vd)随孕周的增长而增加；32周后妊娠期糖尿病胎儿Vs、28周后Vd、24周后应变(S)、收缩期应变率(SRs)、舒张期应变率(SRd)均低于正常胎儿组(均P<0.05)。结论:妊娠期糖尿病胎儿左心室功能受到影响；速度向量成像技术可以反映妊娠期糖尿病胎儿左心室的收缩及舒张功能。

Abstract:: AIM:To explore the value of velocity vector imaging (VVI) technology in detecting fetal left ventricular functions in pregnancy with gestational diabetes mellitus (GDM). METHODS: Digital dynamic fourchamber views of 54 normal fetuses and 54 fetuses with GDM were collected and analyzed offline using VVI. The regional tissue velocity, strain and strain rate of the 6 segments of the left lateral wall and the interventricular septum were measured in systole and diastole. RESULTS: Vs and Vd of fetal left ventricles in pregnancy with gestational diabetes mellitus increased with gestational age. Vs after 32 weeks and Vd after 28 weeks, and S, SRs and SRd after 24 weeks in left ventricles of fetuses with GDM were obviously lower than those of normal pregnancy (P<0.05). CONCLUSIONS: The fetal left ventricular functions are affected in pregnancy with gestational diabetes mellitus. The VVI is a useful method to detect the fetal left ventricular function in pregnancy with gestational diabetes mellitus.
