目的探讨彩色多普勒超声对异常双胎妊娠及妊娠结局的诊断价值。方法 2008年12月-2013年12月选择在秦皇岛市妇幼保健院进行住院分娩的250例双胎妊娠产妇进行均彩色多普勒分析,并对妊娠结局进行比较。结果 250例妊娠产妇大小胎儿的CRL、NT、HR、DVP等各超声指标对比,差异均有统计学意义(P<0.05)。所有胎儿顺利分娩,出现双胎输血综合征3例,双胎反向灌注序列征3例,双胎贫血-多血序列征2例,双胎选择性宫内发育迟缓6例,连体双胎1例,发病率为6.0%。Spearman’s相关性分析结果显示双胎妊娠的妊娠结局与CRL、NT、HR、DVP超声指标检测的差异值有明显相关性(P<0.05)。结论彩色多普勒超声对异常双胎妊娠及妊娠结局的诊断价值高,能及早发现胎儿异常状况并辅助临床干预和评估预后。
Objective To investigate the diagnostic value of color Doppler ultrasound in abnormal twin pregnancy and pregnancy outcome. Methods From December 2008 to December 2013, 250 pregnant women with twin pregnancies who were hospitalized and delivered in Qinhuangdao MCH hospital were selected for color Doppler analysis and pregnancy outcomes were compared. Results The CRL, NT, HR, DVP and other ultrasound indexes in 250 fetuses of pregnant maternal size were significantly different (P <0.05). All fetuses were delivered successfully, with 3 cases of twin transfusion syndrome, 3 cases of twins reverse perfusion sequence, 2 cases of twin anemia - multiple blood syndrome, 6 cases of selective intrauterine growth retardation of twins, 1 case, the incidence rate of 6.0%. Spearman’s correlation analysis showed that the pregnancy outcome of twin pregnancies was significantly correlated with the difference of the ultrasound examination of CRL, NT, HR and DVP (P <0.05). Conclusions Color Doppler ultrasound is valuable in the diagnosis of abnormal twin pregnancies and pregnancy outcomes. Early detection of fetal abnormalities and clinical intervention may be helpful in assessing prognosis.
