宫内生长受限胎儿的主动脉峡部多普勒评估和围产结局的关系

目的探讨宫内生长受限(IUGR)胎儿主动脉峡部(AOI)超声多普勒特点及围产期结局的关系。方法收入41例IUGR患者,根据围产期结局分为两组:围产结局不良组(21例)和围产结局良好组(20例)。对所有病例进行检查及随访,测量参数主动脉峡部、脐动脉、大脑中动脉及静脉导管的搏动指数(pulsatility index,PI),并进行统计学分析。结果 IUGR胎儿围产期不良结局与增高的AOI-PI显著相关(曲线下面积0.7;95%CI,0.52~0.86;P<0.05)。结论 AOI-PI是IUGR胎儿围产期不良结局的独立预测指标,表明AOI的多普勒成像在IUGR胎儿临床监测中的潜在重要作用。

Doppler Assessment of the Aortic Isthmus and Perinatal Outcome in Fetuses with Intraterine Growth Restriction

Objective To investigate the relationship between AOI Doppler ultras-ound and perinatal outcome in IUGR fetuses.Methods Forty-one patients with IUGR were divided into two groups according to the perinatal outcome:adverse perin-atal outcome group(n=21)and good perinatal outcome group(n=20).All cases w-ere examined and followed up,the PI of AOI,UA,MCA and DV were measured and an-alyzed statistically.Results Adverse perinatal outcome of IUGR fetuses was sig-nificantly correlated with the increased AOI-PI(area under the curve 0.7;95%CI,0.52-0.86;P<0.05).Conclusions AOI-PI is an independent predictor of adverse perinatal outcome of IUGR fetuses,indicating that Doppler imaging of AOI plays a potentially important role in the clinical monitoring of IUGR fetuses.
