目的应用速度向量成像( VVI)技术观察妊娠期糖尿病(GDM)孕妇胎儿的左室扭转特点.方法采集98例GDM胎儿和135例正常胎儿的左室短轴心尖和基底水平动态声像图,利用VVI软件测量心内、外膜心尖部和基底部旋转角度峰值,计算扭转角度,并与正常胎儿相应参数进行对比研究.结果 140例胎儿的图像被成功分析.GDM胎儿左室心尖和基底旋转方向可呈顺时针方向,也可呈逆时针方向,但心尖与基底呈反向旋转.左室心内膜旋转和扭转角度大于心外膜(P＜0.05),左室心尖水平旋转角度大于基底水平(P＜0.05).GDM胎儿左室心内膜和心外膜旋转和扭转角度均大于正常对照组(P＜0.05).结论 VVI技术可研究GDM胎儿左室扭转运动,有望成为临床检测胎儿心功能的一种新方法.

Objective To investigate the clinical value of velocity vector imaging (VVI) in the assessment of cardiac torsion in fetuses with gestational diabetes mellitus(GDM).Methods Digital dynamic four-chamber views of 98 fetuses with gestational diabetes mellitus and 135 normal fetuses were collected and analyzed using VVI.Left ventricular(LV) peak apical rotation of endocardium and epicardium at basal and apical level were measured,LV peak torsion was calculated.Results 140 of 233 cases were analyzed successfully.Direction of LV peak apical and basal rotation of endocardium and epicardium in fetus could be clockwise or counter clockwise,however apical and basal level was opposite.LV peak apical and basal rotation of endocardium and epicardium in fetus were stable throughout gestation ( P ＞ 0.05).LV peak rotation of endocardium was higher than that of epicardium in both apical and basal level.The peak rotation　in apical level of endocardium and epicardium was higher than that in basal level( P ＜0.05).LV peak　torsion of endocardium was significantly higher than that of epicardium( P ＜0.05).Compared with normal　group,LV peak rotation of endocardium and LV peak torsion in fetus with GDM were higher( P ＜0.05).　Conclusions VVI can measure the LV rotation and torsion parameters,and evaluate the cardiac function of　GDM fetus.
