Due to an increase in the number of cesarean sections over the past few years, the Incidence of placenta accreta spectrum has considerably grown. We aimed at evaluation of the predictability of simple ultrasound staging system in the women at high risk for placenta accreta spectrum through a prospective observational study. Materials and Methods: The study was a prospective observational cohort. It was conducted in Beni-Suef University Hospitals. It included one hundred and twenty-one pregnant women in 3rd pregnancy trimester and at high risk for placenta accreta spectrum. The examination of all women by transvaginal or transabdominal ultrasound was based on a staging system according to the American Institute of Ultrasound in Medicine “AIUM” developed in 2015. This staging system used simple ultrasound parameters of myometrial placental invasion. Ultrasound staging was done among the participating women. The surgical team documented intraoperative findings and complications in patients’ files postoperatively. The simple descriptive analysis in the form of numbers, percentages & arithmetic means was used for qualitative data. The Student t-Test was used to compare measurements of two independent groups for quantitative parametric data. Results: The placenta was inseparable intraoperatively in 35 women (28.9%). The number of past caesarean sections & gestational age at time of caesarean delivery were associated with intra-operative placental invasion ( p value 0.0001 and 0.01 respectively). Ultrasound staging prediction for placental invasion was 100%. Conclusion: Ultrasound staging of the women at risk of placenta accreta spectrum has a very high predictability and strongly avoids adverse maternal and fetal outcomes through antepartum multidisciplinary delivery planning.","PeriodicalId":12080,"journal":{"name":"Evidence Based Women's Health Journal","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139297584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our populations` cohort were equally randomized into 2 groups, cases – who were subjected to receive metformin from the date of recruitment till termination of pregnancy – and controls – who received nothing – with follow up of the maternal glucose levels and documenting the maternal and fetal outcomes. Results: Metformin appeared to have a good patient acceptability with a less weight gain during enrollment of the trial among the pregnant females with a better glycemic control. There is no difference between the 2 groups regarding incidence of developing GDM, gestational hypertension and fetal macrosomia.

Methods: A descriptive cross-sectional study conducted on 250 non pregnant women attended to outpatient clinic in Mansoura university hospital. Patients with only one cesarean delivery done from 6 to 12 months prior to time of examination were evaluated by three-dimensional trans-vaginal ultrasonography to detect possible cesarean scar niche. The main outcome measure was the presence of cesarean scar niche. Women with cesarean scar niche were compared with those with intact scar (control group). Maternal demographic variables, obstetric and peri-operative variables were analyzed in both groups to detect possible risk factors of cesarean scar niche. Results: Cesarean scar niche was found in 77.2% of study group, with 58.4% of all study group having large defect. The most common shape of cesarean scar niche was triangular (71.6%). The following variables were more detected in cesarean scar defect group than in control group; advanced maternal BMI (as mean BMI in cesarean scar defect group was 27.15 ± 4.17 versus 25.28 ± 2.90 in control group; P value 0.001), presence of active labor (45,6% of women in cesarean scar defect group had active labor versus only 17.5% in the control group; P value ≤ 0.001), peripartum fever (34.2% of cesarean scar defect group had peripartum fever versus only 17.5% in the control group; P value 0.016), and uterine retroversion (uterus was retro flexed in 26.4% in the cesarean scar defect group versus only 12.3% in the control group; P value 0.016). Gestational age at time of delivery and fetal weight were not found to affect the risk of cesarean scar niche formation.
