This examination was assessed the connection between ultrasonographic placental attributes (localisation ,thickness) and fetal umblical doppler stream velocimetry with fetal outcome.This study led at Department of Obstetrics and Gynecology Benha University Hospital , where the patients going to obstetrics outpatient Clinic. During the investigation time frame from June 2017 to May 2018. This investigation included 66 pregnant ladies whose gestational age at 24 weeks incubation from the last typical feminine time frame affirmed by early ultrasound assessment during the first trimester were found in the antenatal center and were followed up at 32 and 36 weeks. Point by point history was taken to preclude clinical and careful ailments that could influence the investigation. US assessment fetal biometry Then assessment of fetal weight (EFW) determined by the recipe of Hadlock et al.,placental thickness ( The placental thickness was estimated by setting the ultrasound transducer oppositely to the plane of the placenta, in the region of the line inclusion, close to the mid-placental bit) and umbilical Doppler examination.All were performed at three visits : first somewhere in the range of 24 and 28weeks, second between 28and 32 weeks, and third somewhere in the range of 32 and 36weeks and fetal result .The investigation indicated measurably critical increment placental thickness in the principal, second and third visit were 25.39 ± 1.88, 30.62 ± 3.25, 36.42 ± 4.3and fetal load in the main, second and third visit were 24.26 ± 1.11, 30.17 ± 1.83, 33.55± 2.14.There is non-huge connection between placental breadth and umbilical conduit stream in the primary second and third visits. There is measurably non-critical connection between's placental breadth in the third visit and APGAR score .So estimations of placental Thickness ought to be incorporated as discrete things on routine U/S reports and can be remembered for sonographic equation with different boundaries as BPD, FL and AC for most exact fetal weight assessment.
