Overview
Brief Summary
Uterine artery doppler measurements will be made at 11-14 weeks and 20-22 weeks of gestation, and the classification of these measurements according to type of delivery; and to investigate the change in the effect of delivery type on uterine artery flows on obstetric outcomes (maternal, fetal, neonatal outcomes).
Detailed Description
The first and second trimester perinatal examination results performed by the same operator from pregnant women who have applied to the clinic since the first trimester are removed from the ViewPoint 6.0 server and database and their uterine artery doppler values (uterine artery PI and RI values, presence of uterine artery notch), placental location, gestational week of measurement, blood pressures, PAPP-A and hCG MoM values, obstetric results (type of birth, week, weight, ante-postpartum complications), data to be generated from other hospital records will be saved to the base
