“…Resistance is reduced and brain development is promoted, so reflecting the contribution of the MCA to HC. [1920] Meanwhile, the RA, which is extremely sensitive to hypoxia and ischemia, tends to contract to redistribute blood flow. Therefore, the S/D, PI, and RI of RA are prone to increasing in order to ensuring the blood supply to major organs of the fetus, such as the brain and liver.…”

Background:The offspring of women with gestational diabetes mellitus (GDM) are prone to macrosomia. However, birth weight is difficult to be correctly estimated by ultrasound because of fetal asymmetric growth characteristics. This study aimed to investigate the correlations between fetal hemodynamics, fetal growth indices in late pregnancy, and birth weight in GDM.Methods:A total of 147 women with GDM and 124 normal controls (NC) were enrolled in this study. Fetal hemodynamic indices, including the systolic/diastolic ratio (S/D), resistance index (RI), pulsatility index (PI) of umbilical artery (UA), middle cerebral artery (MCA), and renal artery (RA), were collected. Fetal growth indices, including biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length, were also measured by ultrasound. Birth weight, newborn gender, and maternal clinical data were collected.Results:The independent samples t-test showed that BPD, HC, and AC were larger in GDM than in NC (P < 0.05). Fetal hemodynamic indices of the UA and MCA were lower (P < 0.05), but those of the RA were higher (P < 0.001) in GDM than in NC. Birth weight was higher in GDM than in NC (P < 0.001). Pearson's correlation analysis showed that hemodynamic indices of the UA were negatively correlated with birth weight, BPD, HC, and AC in both groups (P < 0.05). MCA (S/D, PI, and RI) was negatively correlated with birth weight, HC, and AC in GDM (r = −0.164, −0.206, −0.200, −0.226, −0.189, −0.179, −0.196, −0.177, and − 0.172, respectively, P < 0.05), but there were no correlations in NC (P > 0.05). RA (S/D, PI, and RI) was positively correlated with birth weight in GDM (r = 0.168, 0.207, and 0.184, respectively, P < 0.05), but there were no correlations in NC (P > 0.05).Conclusion:Fetal hemodynamic indices in late pregnancy might be helpful for estimating newborn birth weight in women with GDM.

“…Polycythemia, which is the opposite of an anemic condition, results in decreased fetal blood flow velocity due to increased blood viscosity. In women with GDM, changes in MCA PSV would be expected as a result of the decrease in the velocity of fetal blood flow …”

Objective To compare Doppler ultrasonographic measurements of the fetal middle cerebral artery peak systolic velocity (MCA PSV) among women with or without gestational diabetes mellitus (GDM). Methods A cross‐sectional study was conducted among pregnant women who presented for prenatal care at a single hospital in Brazil between September 11, 2015, and January 6, 2017. Patients were stratified into a group with GDM and a control group without GDM. One Doppler ultrasonographic assessment was performed per participant. This measurement was made after diagnosis but before the start of treatment among women in the GDM group. Fetal ultrasonographic and biometric variables assessed included MCA PSV, MCA pulsatility index, umbilical artery pulsatility index, the MCA–to‐umbilical artery ratio, abdominal circumference, and weight. Results The study included 238 women: 115 in the GDM group and 123 in the control group. The median MCA PSV was 1.02 in the GDM group and 1.08 in the control group (P=0.036). No statistically significant between‐group differences were found for the other fetal ultrasonographic variables or for the fetal biometric variables assessed. None of the maternal or fetal parameters assessed displayed a linear correlation with MCA PSV. Conclusion Doppler ultrasonographic measurements of MCA PSV were lowered among the fetuses of women diagnosed with GDM.

“…Doppler assessment of placental and fetal circulations is a non-invasive method for the evaluation of fetal well-being in high-risk pregnancies (e.g., preeclampsia and intrauterine growth retardation) (5-7). However, application of Doppler ultrasound examination in diabetic pregnancies has revealed conflicting results (8)(9)(10)(11). In fact, despite the widespread use of these techniques, few studies have investigated their effectiveness in improving perinatal outcomes in diabetic women (1).…”

Background: Diabetes mellitus may accompany and complicate a pregnancy, resulting in poor neonatal outcomes. Objectives: The aim of this study was to compare middle cerebral arterial (MCA) and umbilical arterial (UA) Doppler assessments for the evaluation of fetal well-being in mothers with pre-gestational or gestational diabetes mellitus. Methods: This cohort study was performed on 103 pregnant diabetic women, admitted for prenatal care to the department of gynecology and obstetrics of Jame Zanan hospital (Tehran, Iran) in 2015. Sampling was performed, using the convenience method. All women underwent one or more Doppler ultrasound examinations in the third trimester of pregnancy, which included blood flow measurement through umbilical and middle cerebral arteries. Women with abnormal UA or MCA Doppler test results were subjected to labor induction or cesarean section, according to different parameters. The outcomes included neonatal acidosis, oneand five-min Apgar scores, hypoglycemia, hypocalcaemia, neonatal intensive care unit (NICU) admission, gestational age at delivery, and neonatal death. Chi-square test, t-test or Fisher's exact test, and logistic regression analysis were performed to analyze the data. Results: Based on the findings, poor outcomes were detected in 48 women. Nearly 17.5% and 9.7% of women had abnormal UA and MCA Doppler test results, respectively. In total, 62% of women gave birth via cesarean section. The UA Doppler test results were significantly related with hypoglycemia, respiratory distress syndrome (RDS), one-min Apgar score < 7, five-min Apgar score < 7, and NICU admission, while the MCA Doppler results were significantly associated with RDS and neonatal death (P < 0.05). The sensitivity of both tests ranged between 20% and 60%. Logistic regression analysis revealed that UA Doppler test could predict poor outcomes after fasting blood sugar control (P = 0.028, OR = 3.6, CI: 1.15 -11.13). Conclusions: Both UA and MCA Doppler tests were associated with some neonatal outcomes. However, sensitivity of both UA and MCA assessments was low in the prediction of adverse neonatal outcomes. By the comparison of these two methods, we found that UA Doppler assessment is a better predictor of neonatal outcomes.
