In a prospective study we investigated 100 twin pregnancies in order to assess the predictive value of doppler-sonographic measurements regarding the pregnancy outcome. We used the pulsatility index of the uterine arteries, the umbilical artery, the fetal aorta thoracica and the fetal middle cerebral artery. The measurements were obtained at various gestational ages between 24 and 32 weeks. Significant differences between unselected twin pregnancies and normal single pregnancies were not found. Moreover, there is no relation between the severity of an impaired perfusion and an adverse outcome of the pregnancy. The prediction of fetal distress (hypoxia, preterm birth, poor fetal growth, acidosis, and disturbed neonatal adaption) with doppler-score has a sensitivity of 25% and a positive predictive value of 63%. From this rather insufficient result we conclude that doppler screening in unselected twin pregnancies hardly proves to be useful.
在一项前瞻性研究中，我们调查了100例双胎妊娠，以评估多普勒超声测量对妊娠结局的预测价值。我们使用了子宫动脉、脐动脉、胎儿胸主动脉和胎儿大脑中动脉的搏动指数。测量在孕24至32周的不同孕周进行。未发现未选择的双胎妊娠与正常单胎妊娠之间存在显著差异。此外，灌注受损的严重程度与妊娠不良结局之间没有关系。用多普勒评分预测胎儿窘迫（缺氧、早产、胎儿生长受限、酸中毒和新生儿适应障碍）的敏感性为25%，阳性预测值为63%。从这个相当不理想的结果中我们得出结论，在未选择的双胎妊娠中进行多普勒筛查几乎没有用处。
