The mean peak systolic to end-diastolic (S/D) umbilical artery ratio was measured in 291 Doppler studies performed during pregnancy in 35 insulin-dependent diabetic women. A normal decline was observed in the umbilical artery S/D ratio, from 4.2 +/- 0.21 at 18 weeks to 2.18 +/- 0.22 at 38 weeks. There was no significant correlation between mean third-trimester S/D and either glycosylated hemoglobin (r = 0.25) or mean blood glucose levels (r = 0.15). Fetuses of women with vascular disease (class… CONTINUE READING
