Doppler ultrasonographic assessment of fetal middle cerebral artery peak systolic velocity in gestational diabetes mellitus

Abstract

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.

Altered Doppler Velocimetry of Fetal Middle Cerebral Artery in Singleton Pregnancies Complicated by Mild Well-Controlled Gestational Diabetes

“…They added that UA indexes are more sensitive to the size of the fetus than to the presence or absence of GD. In a retrospective study, Dantas et al [9] compared Doppler ultrasonographic measurements of fetal MCA-PSV among 238 women with or without GD. ; the authors did not find any statistically significant dif- ferences between groups in fetal velocimetric or biometric variables.…”

“…Salvesen et al [6] and Ben-Ami et al [7] did not show any abnormal Doppler indices in fetuses of mothers with GD. To and Mok [8] showed that umbilical velocimetry had no predicting value for abnormal neonatal outcomes in pregnancies complicated by GD, and Dantas et al [9] did not find any statistically significant differences in ultrasonographic measurements of fetal peak systolic velocity of MCA (MCA-PSV).…”

Detection of Gestational Diabetes Mellitus and Influence on Perinatal Outcomes from B-Mode Ultrasound Images Using Deep Neural Network

“…Some scholars believe that the age of pregnant women is related to the occurrence of GDM [9]. Dantas et al [10] found that after pregnancy, the pregnancy age, preference for sweets, and family history of DM were risk factors for GDM. Kim et al [11] found that as women's age at first pregnancy increased, the probability of GDM increased, and age at first pregnancy was one of the independent risk factors for GDM.…”
