摘要/Abstract

摘要： 为分析孕晚期生长受限（FGR）胎儿脐动脉、大脑中动脉和主动脉弓峡部彩色多普勒超声血流参数变化及其对FGR的诊断价值，选取2018年5月~2019年3月于我院产检且确诊为FGR的孕晚期（孕周34~36周）孕妇51例作为观察组，另选取同期正常妊娠的孕晚期（孕周34~36周）孕妇47例作为对照组。采用GE voluson E8彩色多普勒超声诊断仪测量并比较两组胎儿脐动脉和大脑中动脉以及主动脉弓峡部的多个血流参数，如搏动指数（PI）、阻力指数（RI）、收缩期末流速（PSV）、收缩期末反流流速（ESRV）、舒张期末流速（EDV）和PSV/EDV（S/D）等。测量结果发现，观察组胎儿脐动脉PI、RI、S/D及主动脉弓峡部ESRV水平均高于对照组，大脑中动脉PI、RI及主动脉弓峡部PSV/ESRV水平均低于对照组，差异均有统计学意义（P<0.05）；两组胎儿大脑中动脉、主动脉弓峡部PSV水平比较差异均无统计学意义（P>0.05）。本研究证实孕晚期FGR胎儿脐动脉、大脑中动脉和主动脉弓峡部彩色多普勒超声血流参数均发生了一定变化，其中脐动脉和大脑中动脉PI、RI、S/D及主动脉弓峡部ESRV、PSV/ESRV均可作为诊断FGR的敏感指标。

Abstract: To analyze the changes of color Doppler flow imaging parameters of umbilical artery, middle cerebral artery and isthmus of aortic arch in fetal growth restriction (FGR) in late pregnancy, and its diagnostic value for FGR, 51 late pregnant women diagnosed as FGR in our hospital from May 2018 to March 2019 were selected as observation group, and 47 late pregnant women with normal pregnancy in the same period were selected as control group. The gestational weeks of the two groups were 34~36 weeks. The blood flow parameters such as pulsation index (PI), resistance index (RI), peak systolic velocity(PSV), end systolic reflux velocity(ESRV), end diastolic velocity(EDV), PSV/EDV(S/D) of umbilical artery, middle cerebral artery and isthmus of aortic arch were measured by GE voluson E8 color Doppler ultrasound, and the data were compared between the two groups. The results showed that, the levels of PI, RI, S/D in umbilical artery and ESRV in isthmus of aortic arch in the observation group were higher than those in the control group, the levels of PI, RI in middle cerebral artery and PSV/ESRV in isthmus of aortic arch were lower than those in control group, the difference was statistically significant (P<0.05). There was no significant difference in PSV levels between the two groups (P>0.05). In a word, blood flow parameters of umbilical artery, middle cerebral artery and isthmus of aortic arch of FGR fetus in late pregnancy changed to some extent. Among them, PI, RI, S/D of umbilical artery and middle cerebral artery, ESRV and PSV/ESRV of isthmus of aortic arch can be used as sensitive indicators for FGR diagnosis.

Key words: late pregnancy, fetal growth restriction, umbilical artery, middle cerebral artery, isthmus of aortic arch, color Doppler flow imaging
