Umbilical artery blood flow velocity waveforms in pregnancy complicated by diabetes mellitus

Abstract: Umbilical artery blood velocity waveforms were recorded by a pulsed Doppler system in the third trimester of pregnancy in 16 diabetic women (12 class B, 1 class C, 3 class D) and the waveforms were analysed for resistance index (RI = peak systolic velocity minus end diastolic velocity/peak systolic velocity). There was no significant correlation between the RI values and either serum glucose (r = 0.385) or fructosamine levels (r = 0.380). However, the RI values were raised in two cases with serum glucose level… Show more

“…In agreement with our results, Ishimatsu et al (2018), measured impedance to flow in the middle cerebral artery in 43 pregnant women with well-controlled diabetes mellitus at 24-38 weeks of gestation. The PI was within the normal range and was not significantly associated with maternal serum glucose, fructosamine or glycosylated hemoglobin level [16]. Leung et al (2017), found that, Doppler study of the umbilical.…”

“…This suggests that external stimuli can affect the fetal circulation, probably by altering blood flow. However, in Doppler assessments of diabetic pregnant women, Ishimatsu et al 4 failed to find a significant correlation between Doppler indices and serum glucose or fructosamine concentrations. Reece et al 7 reported normal Doppler findings in the fetal umbilical artery in diabetic pregnant patients without vasculopathy, but in patients with known vasculopathy, they found a tendency toward a higher than normal S:D in those who experienced an adverse outcome.…”

“…Hemodynamic studies of pregnant women with diabetes (pre-existing or gestational) have shown Doppler flow velocimetric data from the uterine and umbilical arteries to be generally poor predictors of glycemic control or pregnancy outcome. [3][4][5][6] However, in a small percentage of such patients and in patients with known vasculopathy, elevations in Doppler indices may be associated with adverse perinatal outcomes. [5][6][7] Adverse perinatal outcomes have also been noted in healthy pregnant patients who have undergone glucose tolerance testing.…”

“…For other authors [10][11][12], on the contrary, IDD without vascular complications had no conse quence on the umbilical diastolic index. They found no relation between glycosylated hae moglobin or the average glycaemia and the umbilical diastolic index.…”
