对内蒙古医科大学附属医院2011年9月至2012年5月的1715例孕17-34周胎儿进行规范化产前超声检查结果分析研究,得知在1715例胎儿中,超声检查诊断胎儿畸形65例(3.79%),其中蒙族10例(0.58%),汉族54例(3.15%),其他少数民族1例(0.06%).超声软指标阳性检出96例(5.6%),蒙族16例(0.93%),汉族76例(4.43%),其他少数民族4例(0.23%).现有数据显示蒙古族胎儿畸形检出率以及软指标阳性率均较汉族胎儿低,但无统计学差异.中枢神经系统畸形、骨骼系统畸形、胃肠道系统畸形分列胎儿结构畸形前三位.心室内斑点样强回声和肾盂轻度扩张是最常见的软指标阳性,在产前诊断中需加强咨询和随访.
The normal prenatal ultrasound examination results of 1715 fetuses aged 17-34 weeks from September 2011 to May 2012 in the Affiliated Hospital of Inner Mongolia Medical University were analyzed and analyzed.

Ventricular speckle strong echo and mild renal pelvis dilatation is the most common positive soft index in prenatal diagnosis need to strengthen the consultation and follow-up .
