Background: Placenta previa and placenta previaaccreta are severe pregnancy complications with maternal morbidity had been reported to occur in up to 60% and mortality in up to 7% of women with placenta accreta. In addition, the incidence of perinatal complications is also increased mainly due to preterm birth and small for gestational age fetuses. Objectives: The aim of this study was to investigate whether different placental morphological features and uterine artery Doppler can predict maternal and fetal outcome in pregnancies complicated with placenta previa and placenta accreta. Patients and Methods: This study was done at Al-Hussien Obstetrics-Gynaecology department during the period from June 2019 till December 2019, patients were selected from outpatient clinic, ultrasound unit, and patients admitted in Al-Hussien Obstetrics-Gynaecology department. It is a prospective observational study on 30 patients with placenta previa including placenta previaaccreta compared to 30 patients with normal pregnancies. This was done to assess if uterine artery Doppler and Placental morphological Features could be predictors of peripartum complications in cases with Placenta Previa and Placenta Previaaccreta. Results: There were significant relations between location of the placenta, presence of lacunae, absent echo lucent space and placental vascularity and the three groups, with no relation with bladder uterine interface.   There were significant relations between CS hysterectomy, blood transfusion, NICU, bladder injury, ICU, preterm labour and the 3 groups. This shows significant co relations between different types of placentae and neonatal birth weight. There was significant relation between uterine artery PI and the 3 groups, with no significance with RI. There were significant relations between presence of lacunae and CS hysterectomy, blood transfusion, NICU, bladder injury, ICU admission preterm labour, - as p value was less than 0.001-, with no significance with maternal mortality and neonatal death. There were significant relations between PI of uterine artery doppler and apgar score in 1& 5 min with p value 0.007 and less than 0.001 respectively, with no relation with IUGR. Conclusion: From results of our study we can conclude that ultrasound has a high diagnostic value in diagnosing placenta previa and placenta previaaccreta by certain placental morphological features. High grade of placental lacunae and moderate placental vascularity were highly associated with maternal and fetal complications.
