摘　　要：目的探讨时间-空间相关成像(spatiotemporal image correlation,STIC)技术在脐绕颈胎儿左心室收缩功能评价中的应用价值及与围生儿预后的关系。方法收集2019年10月至2020年11月产检且胎儿有脐绕颈孕妇78例作为研究对象,根据脐绕颈周数分为:脐绕颈1周组(A组)、脐绕颈≥2周组(B组),选择同期胎儿无绕颈孕妇151例作为对照组,应用STIC技术测量所有胎儿左心室收缩末期容积(LVESV)及左心室舒张末期容积(LVEDV),通过计算得到左心室每博输出量(LVSV)、左心室心排血量(LVCO)及左心室射血分数(LVEF)。并追踪孕妇的分娩方式及新生儿出生后1 min Apgar评分情况。结果与对照组相比,A组胎儿LVESV、LVEDV、LVSV、LVCO及LVEF差异均无统计学意义(P>0.05),与对照组及A组相比,B组胎儿LVESV、LVEDV均增大,差异均有统计学意义(P<0.05),LVSV、LVCO以及LVEF均减小,差异均有统计学意义(P均<0.05);与对照组产妇相比,A组产妇自然分娩率、阴道助产分娩率及剖宫产率均无统计学意义(P>0.05),与对照组及A组产妇相比,B组产妇自然分娩率降低,差异有统计学意义(P<0.05),剖宫产率升高,差异有统计学意义(P<0.05),阴道助产分娩率差异无统计学意义(P>0.05);与对照组新生儿相比,A组新生儿窒息率无统计学意义(P>0.05),与对照组及A组新生儿相比,B组新生儿窒息率升高,差异有统计学意义(P<0.05)。结论STIC技术可作为评价脐绕颈胎儿左心室收缩功能的一种方法,对指导产科医师采取合适的分娩方式,降低围生儿死亡率,提高新生儿生活质量有较高的临床应用价值。Objective To investigate the application value of spatiotemporal image correlation(STIC)technique in evaluation of left ventricular systolic function of the fetus with cord round the neck and its correlation with the prognosis of perineonates.Methods A total of 78 pregnant women with fetuses being cord round the neck who underwent dilivery examination were enrolled.According to the loop of cord around neck,the fetuses were divided into group A(one loop of cord around neck)and group B(two or more loops of cord around neck),moreover,the other 151 fetuses without cord round the neck were enrolled as control group.The left ventricular end systolic volume(LVESV),left ventricular end-diastolic volume(LVEDV),left ventricular stroke volume(LVSV),left ventricular cardiac output(LVCO),and left ventricular ejection fraction(LVEF)were detected by using STIC technique.Moreover the delivery mode of pregnant women and the postnatal 1min Apgar score of neonates were observed and compared among the 3 groups.Results There were no significant differences in LVESV,LVEDV,LVSV,LVCO and LVEF between group A and control group(P>0.05).The LVESV and LVEDV in group B were significantly higher than those in control group and group A(P<0.05).The LVSV、LVCO and LVEF in group B were significantly lower than those in control group and group A(P<0.05).There were no significant differences in natural delivery rate,vaginal delivery rate and cesarean section rate between the A group and control group(P>0.05).The natural delivery rate in group B was significantly lower than that in control group and group A(P<0.05),however,the cesarean section rate in group B was significantly higher than that in control group and group A(P<0.05).There were no significant differences in vaginal delivery rate and uterine-incision delivery rate between group A and control group(P>0.05).However the incidence rate of neonatal asphyxia in group B was significantly higher than that in control group and group A(P<0.05).Conclusion STIC technique can be used as a method to
