| 摘 要： | 目的 应用多普勒技术观察妊娠11+0～14+6周正常胎儿心脏大血管的血流动力学参数.方法 对230位正常妊娠孕妇在11+0～14+6周进行常规超声检查,同时观察胎儿心脏大血管.结果 主动脉血流速度高于主肺动脉和动脉导管,与孕周之间呈正相关,大动脉的射血时间与孕周之间呈正相关,而射血加速时间与孕周之间呈负相关;妊娠11～14周胎儿静脉导管显示率相对较低,而静脉导管的血流速度、搏动指数、阻力指数与孕周之间无相关性;至妊娠13周以后主动脉、主肺动脉、动脉导管的流速、射血时间和射血加速时间以及静脉导管的血流参数相对恒定.结论 妊娠13周以后可进行胎儿早期超声心动图检查,但胎儿心脏大血管的观察难度较大.胎儿心脏大血管的血流动力学表现可直接反映大血管本身状况,也可间接反应心脏的功能.当胎儿心脏结构或功能发生异常时,有可能引起大血管血流动力学的改变.
