“…The terminology "placenta accreta" was used by 27 authors of case reports [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][46][47][48][50][51][52]54,55 , "morbidly adherent placenta" by two 45,49 and "abnormal placentation" in one report. 53 Two authors reporting on three cases did not describe the past surgical history. 25,40 In five (14.3%) cases there was a previous history of uterine curettage only 28,30,31,50,51 and in seven (20.0%) the women presented with a combined history of CD, myomectomy and/or curettage.…”

The wide heterogeneity in terminology used to describe the grades of accreta placentation and differences in study design limits the evaluation of the accuracy of ultrasound imaging in the screening and diagnosis of placenta accreta. This review emphasizes the need for further prospective studies using a standardized evidence-based approach including a systematic correlation between ultrasound signs of placenta accreta and detailed clinical and pathologic examinations at delivery.

“…Besides the ultrasound diagnostic signs, there are certain MRI indices that are used when placental abnormalities are suspected, with low sensitivity and specificity (80 -88.8% and 65 -86.6% respectively) (12)(13)(14). In 2017, A. Valentini et al published a study which followed the retrospective evaluation of the MRI images obtained during pregnancy (26-37 weeks of gestation).…”

Introduction. The incidence of Caesarian section has increased remarkably in recent years, which also leads to the increased maternal and fetal morbidity due to the complications that occur after the changes in the myometrial structure of the uterine scar. Placental anomalies with an increased risk for both the mother and the fetus are known under the heading of AIP (abnormally invasive placentation). Approximately 80% of the cases of placental anomalies are associated with a history of Caesarian delivery, curettage or myomectomies with the opening of the uterine cavity. Aims and scope. The present paper aims at highlighting the current techniques of diagnosing placental abnormalities from the first trimester of pregnancy. Several studies in the specialty literature have been evaluated, those published in the last 5 years (2015-2019) on the PubMed platform, the results being presented in the form of a review. Results. In 2018, Pagani et al. conducted a meta-analysis on 20 studies in the specialty literature. The current techniques used to diagnose placental abnormalities are abdominal and transvaginal ultrasound and Doppler ultrasound. A number of 7 studies (721 cases) used ultrasound to diagnose abnormalities. The identification of the degree of invasion was performed with a specificity of 97.1%-placenta accreta, 98.4%-placenta increta, 98.9%-placenta percreta and a sensitivity of 90.6%, 93% and 81.2% respectively. The main signs evidenced upon ultrasound, which are currently used by most authors in specialized studies are: the loss/ the interruption of the hypoechoic area at the level of the myometrium under the placental bed, placental gaps (which may exhibit turbulent blood flow), the interruption of the hyperechoic line represented by the posterior bladder wall and the uterine serous membrane at this level, the thinning of the myometrium (reaching < 1mm), the presence of an exophytic formation which exceeds the uterine serous membrane, infiltrating into the urinary bladder. The echo Doppler images reveal: blood flow at the level of the placental gaps, intense vascularization in the subplacental area and vesicouterine hyper-vascularization. In a paper published in 2018, Cali et al. highlighted the importance of identifying these ultrasound signs from the first trimester of pregnancy. The accuracy of diagnosing AIP in the first trimester is low compared to the 2 nd and 3 rd trimesters: the loss of the hypoechoic area 84.3% vs. 92.4%, the presence of placental gaps 78.3% vs. 100%, the interruption of the hyperechoic line at the level of the urinary bladder 75.9% vs. 93.3%, vesicouterine hyper-vascularization 50.6% vs. 81%. Conclusions. The importance of making an accurate diagnosis, as early as possible, of a placental anomaly is vital. The close monitoring of the pregnant woman, with serial ultrasounds performed quarterly, which should follow the signs indicated until so far in the specialized studies, as well as the preparation of a multidisciplinary operative team increases the probability of giving birth to...

“…In the current study, different sensitivity, specificity, positive predictive value, and negative predictive value were obtained for each of the ultrasonographic parameters of diagnosing placenta accreta. The increased rate of the cesarean section over the past decades has led to an increase in the number of cases of placenta previa and placenta accrete [14] . Hemorrhage and surgical complications in cases of morbidly adherent placenta are directly associated with the depth of the invasion and the involvement of adjacent organs.…”
