In a group of 311 high-risk pregnancies the result of the first ultrasound and Doppler sonographic examinations were retrospectively compared with the results of the pregnancies. The aim of the study was to determine the value of the methods--single and in combination--in respect of the major foetal risks. It can be shown that the already established ultrasound screening can be improved by simultaneous Doppler sonography, because the increase in sensitivity by the combined examination exceeds the decrease in specificity. In respect of all proven risks--malformation, growth retardation, prematurity and foetal mortality--a sensitivity of 66.7% and a specificity of 77.8% is attained by only one combined ultrasound/Doppler examination. Thus, the identification of a high-risk group (which needs intensive surveillance and therapy) can be improved in comparison to ultrasound examination alone.
在一组311例高危妊娠中，对首次超声和多普勒超声检查结果与妊娠结局进行了回顾性比较。本研究的目的是确定这些方法（单独使用和联合使用）在主要胎儿风险方面的价值。结果表明，同时进行多普勒超声检查可改善已确立的超声筛查，因为联合检查提高的敏感性超过了降低的特异性。对于所有已证实的风险——畸形、生长迟缓、早产和胎儿死亡——仅进行一次超声/多普勒联合检查就能达到66.7%的敏感性和77.8%的特异性。因此，与单独的超声检查相比，高危组（需要强化监测和治疗）的识别可以得到改善。
