【摘要】：目的探讨孕晚期宫内生长受限(FGR)胎儿脐动脉、大脑中动脉、主动脉峡部血流参数变化。方法选取孕晚期胎儿FGR孕妇40例(观察组),同期胎儿宫内发育正常孕妇100例(对照组),分别于孕32~34、34~36、36~40周时进行彩色多普勒超声,测量脐动脉搏动指数(PI)、阻力指数(RI)及收缩期末流速(PSV)、舒张期末流速(EDV),计算PSV/EDV(S/D);大脑中动脉搏动指数(PI)、阻力指数(RI)及收缩期末流速(PSV);主动脉峡部PSV、收缩末反流流速(ESRV)及二者比值(PSV/ESRV)。结果观察组孕32~34、34~36、36~40周时胎儿脐动脉PI、RI、S/D均高于对照组;胎儿大脑中动脉PI、RI均低于对照组;胎儿主动脉峡部ESRV均高于对照组,PSV/ESRV均低于对照组;组间比较P均0.05。两组各时间点胎儿大脑中动脉及主动脉峡部PSV比较差异均无统计学意义(P均0.05)。结论孕晚期胎儿宫内生长受限胎儿脐动脉、大脑中动脉、主动脉峡部血流参数均出现改变,脐动脉和大脑中动脉PI、RI、S/D以及主动脉峡部ESRV、PSV/ESRV均可作为评价FGR的敏感指标。
[Abstract]:Objective to investigate the fetal umbilical artery and middle cerebral artery (MCA) with intrauterine growth restriction (FGR) in the third trimester of pregnancy. Methods 40 pregnant women with fetal FGR in late pregnancy (observation group) and 100 pregnant women with normal intrauterine development (control group) were selected. Measurement of umbilical artery pulsatility index (Pi), resistance index (RI) and end-systolic flow velocity (PSV), end diastolic velocity (EDV), calculation of PSV / EDV / D, middle cerebral artery pulsatility index (Pi), resistance index (RI) and end-systolic velocity (PSV); aortic isthmus (PSV), end-systolic reflux velocity (ESRV). Results in the observation group, the ratio of PSV / ESRV was significantly higher than that in the control group at the gestational age of 32 ~ 34 ~ (34) and 36 ~ 36 ~ 40 weeks after gestation, and the RII / D of the fetal umbilical artery was significantly higher than that of the control group. The ESRV in the isthmus of fetal aorta was higher than that in the control group, and the ratio of PIRI in the fetal middle cerebral artery was lower than that in the control group. There was no significant difference in PSV of middle cerebral artery and aortic isthmus between the two groups (P < 0.05). Conclusion the fetal umbilical artery, middle cerebral artery and middle cerebral artery have intrauterine growth restriction in the late trimester of pregnancy. The blood flow parameters of aortic isthmus were all changed. The RIS / D of umbilical artery and middle cerebral artery and the PSV / ESRV of aortic isthmus could be used as sensitive indexes to evaluate FGR.
