Measure
Pregnant Women With Gestational Diabetes
case group The investigation will be performed to pregnant women with gestational diabetes 1. Calculation of gestational age will be based on the last reliable menstrual period or the first trimester ultrasound. 2. Ultrasound examination will be performed twice at 27-28 weeks and 36-37 weeks of gestation prospectively. During ultrasound, fetal biometry (biparietal diameter, abdominal circumference, femur length) and estimated fetal weight will be calculated automatically according to hadlock's formula additionally, the sonographic cross sectional area of umbilical cord, the umbilical arteries and umbilical vein will be measured in a free loop of the umbilical cord using the software of the ultrasound device. The cross sectional area of Wharton's jelly will be computed by subtracting the cross sectional area of the vessels from that of the umbilical cord and the interventricular septum thickness will be measured. 3. HbA1c levels will be measured for diabetes patients.
Non Diabetic Pregnant Women
control group The investigation will be performed to non diabetic pregnant women: 1. Calculation of gestational age will be based on the last reliable menstrual period or the first trimester ultrasound. 2. Ultrasound examination will be performed twice at 27-28 weeks and 36-37 weeks of gestation prospectively.
