Background: The relationship between placental localization and fetus is unclear. This study was aimed to determine the relationships between placental localization, ultrasound findings and pregnancy outcomes of the third trimester of pregnancies. Materials and Methods: Three-hundred and two women were included in the study. Maternal age, gravidi-ty, parity, abortion and live birth numbers, types of previous births, gestational age, femur length (FL), bipa-rietal diameter (BPD), head circumference (HC), abdominal circumference (AC), placental localization (ante-rior/posterior/lateral/fundus), umbilical artery systolic/diastolic ratio (S/D), fetal presentation, type of deliv-ery, post-partum parameters of infant were obtained from archive records. Results: The placentas were located in the anterior, posterior, fundal and lateral uterine wall in 38.1%, 30.1%, 19.9%, and 11.9% of individuals, respectively. Measurements of the HC in the third trimester were differed according to the localization of the placenta, and the HC measurements were significantly higher if the placental localization was anteriorly (p=0.045). There were no differences in other ultrasonographic measurements (S/D, BPD, AC ve FL), in the height, weight, and gender of the baby, gestational week at delivery, APGAR scores and type of delivery according to the placental localization (p>0.05). Conclusions: In this study, we found that placental localization did not affect pregnancy outcomes, type of delivery and gender of the baby in risk-free, spontaneous and single pregnancies in the third trimester. Also, we stated that the previous birth type did not give an idea about placental localization. We think that placenta implantations, except placental location anomaly and invasion anomaly, do not provide precise information about pregnancy outcomes and type of delivery.
