Efficacy and safety of management of placenta accreta spectrum by transverse uterine fundal incision in a single tertiary care centre: A retrospective study.

Background We assessed the efficacy and safety of management of morbidly adherent placenta by the transfundal uterine incision approach. As a secondary outcome measure, we compared ultrasound and magnetic resonance imaging (MRI) for the diagnosis of adherent placenta. Methods We retrospectively analysed the records of 5 years of women with adherent placenta. Twenty-five women with an antenatal diagnosis of placenta increta and percreta operated by transfundal uterine incision were included. Blood loss, transfusion requirements, operative injuries, and maternal and neonatal intensive care unit (ICU) stay were compared among three different types of adherent placenta. Surgical and other outcome measures were also analysed. Results On antenatal screening with ultrasound, an accurate diagnosis could be achieved in all cases of increta and two-thirds of percreta. Antenatal diagnosis by MRI detected 93.3% of increta and all percreta cases. The mean (SD) gestation at delivery was 34 (4.9) weeks in accreta, 34.9 (2.7) weeks in increta and 31 (4.8) weeks in percreta patients. The mean blood loss encountered intraoperatively was 1012.5 (193.1) ml, 1566.67 (566.52) ml and 1591.67 (629.61) ml in accreta, increta and percreta patients, respectively. Inadvertent bladder injury occurred in 3 women who had placenta percreta invading the bladder. There was no long-term morbidity and no mortality. Conclusion Transfundal incision for delivery of baby is associated with the advantage of avoiding the placenta thereby minimizing blood loss.

A rare case of maternal foetal death caused by uterine rupture in the placenta accreta.

Background: Fetal death has various causes, among the most common are problems relating to the placenta, such as placental abruption or placental malformations such as placenta accreta. From the literature, it emerges that placental analysis at autopsy can allow for greater resolution of cases compared to clinical history and external examination of the fetus alone. Case Report: We report the case of a woman at the eleventh week of pregnancy who died in hospital. The medical history revealed two further previous pregnancies, both with births by cesarean section. The autopsy identified the cause of maternal death as acute cardiorespiratory arrest secondary to hemorrhagic shock from spontaneous uterine rupture. Hemorrhagic infiltrate was found in the intervillous placental spaces with rupture of the uterus due to placenta previa and accreta. Discussion: Placenta accreta is a condition in which a pathological adherence and/or invasion of the myometrium by the placenta is observed. This condition poses a problem during recovery with potential for severe bleeding. Therefore, we emphasize the macroscopic and histological analysis of the placenta, uterus and the ovaries in all cases of maternal-fetal death, suggesting however that the organs be analyzed both by gross analysis and after permanence in formaldehyde. Furthermore, in these cases, it is important to evaluate the clinical history and data, especially ultrasound scans performed in life, or insertion anomalies during instrumental investigations. For this reason, we recommend to collaborate with a multidisciplinary team in these cases, including the gynecologist and the forensic pathologist.

Intraoperative and Postoperative Outcomes of Pfannenstiel and Midline Skin Incisions in Placenta Accreta Spectrum Disorders: Single-Center Experience.

Background: We compared Pfannenstiel and midline skin incisions for cesarean hysterectomy in women with confirmed Placenta Accreta Spectrum Disorders. Aims: A retrospective cohort study was conducted to evaluate the outcomes of Pfannenstiel and midline skin incisions in women undergoing cesarean section hysterectomy for suspected placenta accreta at Akdeniz University Hospital between January 2010 and February 2022. Histopathological confirmation was obtained for all cases. Demographic, perioperative, and postoperative data, along with neonatal outcomes, were extracted from the hospital's electronic database. Possible complaints related to the incision site or other issues (e.g., vaginal dryness or sexual life) were identified through telephone interviews. Subjects were stratified into Pfannenstiel and midline incision cohorts, with subsequent data comparison. Results: Data from 67 women with a histopathologically confirmed PAS diagnosis were analyzed. Of these, 49 (73.1%) underwent Pfannenstiel incision, and 18 (26.9%) had a midline skin incision. Incisions were based on the surgeon's experience. Pfannenstiel incision was more common in antepartum hemorrhage, preoperative hemorrhage, and emergency surgery (p = 0.02, p = 0.014, p = 0.002, respectively). Hypogastric artery ligation occurred in 30 cases (61.2%) in the Pfannenstiel group but none in the midline group. Cosmetic dissatisfaction and sexual problems were more prevalent in the midline group (p < 0.05, all). Preoperative and postoperative blood parameters, transfused blood products, and neonatal outcomes were similar between the two groups. Conclusions: Relaparotomy, bladder injury, blood loss, and need for blood transfusion were more prevalent in the Pfannenstiel group, while greater dissatisfaction with the incision was observed in the midline incision group. Midline incision seems to be more favorable in patients with Placenta Accreta Spectrum (PAS). Patients may be informed regarding the worse cosmetic outcomes and possible sexual problems related to vaginal dryness when midline laparotomy is planned. But before opting for a Pfannenstiel incision, patients should receive comprehensive information regarding the potential risks of relaparotomy and bladder injury.

Placenta Accreta Spectrum (PAS): Diagnosis, Clinical Presentation, Therapeutic Approaches, and Clinical Outcomes.

Placenta accreta spectrum (PAS) refers to the abnormal adhesion of the placenta to the myometrium, with varying degrees of severity. Placenta accreta involves adhesion to the myometrium, placenta increta invades the myometrium, and placenta percreta extends through the serosa to adjacent organs. The condition is linked to deficient decidualization in scarred uterine tissue, and the risk increases when placenta previa is present and with each prior cesarean delivery. Other risk factors include advanced maternal age, IVF, short intervals between cesareans, and smoking. PAS incidence has risen due to the increase in cesarean deliveries. Placenta previa combined with PAS significantly raises the risk of severe peripartum bleeding, often necessitating a cesarean section with a total hysterectomy. Recognizing PAS prepartum is essential, with sonographic indicators including intraplacental lacunae and uterovesical hypervascularization. However, PAS can be present without sonographic signs, making clinical risk factors crucial for diagnosis. Effective management requires a multidisciplinary approach and proper infrastructure. This presentation covers PAS cases treated at University Hospital Freiburg, detailing patient conditions, diagnostic methods, treatments and outcomes.

Prolonged adhesiolysis to pregnancy interval is associated with placenta accreta spectrum in women with intrauterine adhesion.

BACKGROUND: Both the trauma of endometrium and hysteroscopic adhesiolysis can lead to a high rate of placenta accreta spectrum (PAS) in women with intrauterine adhesion (IUA). This study analysed the impact of time interval from adhesiolysis to pregnancy on PAS in IUA women. METHODS: Patients diagnosed with IUA who underwent adhesiolysis in Anhui Women and Children's Medical Centre between January 2016 and December 2020 were included in this case-series study. Clinical data were obtained from electronic medical records and telephone interviews. RESULTS: Among a total of 102 IUA women with successful pregnancies, 8 (7.8%) suffered from miscarriages with PAS, and 94 (92.2%), 47 with PAS and 47 without PAS, had successful delivery. The total prevalence of PAS in pregnant women with IUA was 53.9% (55/102). The average time from adhesiolysis to pregnancy in the PAS group was significantly longer than in the non-PAS group (14.2 ± 5.7 vs. 10.3 ± 4.4 months, p = 0.000). Regression analysis showed that AFS grade (OR = 7.40, 95% CI 1.38-39.73, p = 0.020) and adhesiolysis to pregnancy interval time between 12 and 24 months (OR = 12.09, 95% CI 3.76-38.83, p = 0.000) were closely related to PAS. A Kaplan-Meier analysis showed the median interval time to PAS was 16.00 months (95% CI 15.11-16.89). CONCLUSIONS: We assume that prolonged adhesiolysis to pregnancy interval may be considered a significant risk factor for PAS in IUA women.

Both the trauma of endometrium and hysteroscopic adhesiolysis can result in a high rate of placenta accreta spectrum in women with intrauterine adhesion. This study analysed the impact of time interval from adhesiolysis to pregnancy on placenta accreta spectrum in intrauterine adhesion women. This case-series study included patients diagnosed with intrauterine adhesion who underwent adhesiolysis in Anhui Women and Children's Medical Centre between January 2016 and December 2020. Clinical data were obtained from electronic medical records and telephone interviews. We assume that prolonged adhesiolysis to pregnancy interval may be considered a significant risk factor for placenta accreta spectrum in intrauterine adhesion women.

Maternal outcomes of conservative management and cesarean hysterectomy for placenta accreta spectrum disorders: a systematic review and meta-analysis.

BACKGROUND: Cesarean hysterectomy as a traditional therapeutic maneuver for placenta accreta spectrum (PAS) has been associated with serious morbidity, conservative management has been used in many institutions to treat women with PAS. This systematic review aims to compare maternal outcomes according to conservative management or cesarean hysterectomy in women with placenta accreta spectrum disorders. METHODS: A systematic literature search was performed in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, and four Chinese databases (Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chinese Wanfang database and VIP database) to May 2024. Included studies were to be retrospective or prospective in design and compare and report relevant maternal outcomes according to conservative management (the placenta left partially or totally in situ) or cesarean hysterectomy in women with PAS. A risk ratio (RR) with 95% confidence interval (95% CI) was calculated for categorical outcomes and weighted mean difference (WMD) with 95% CI for continuous outcomes. The Newcastle-Ottawa Quality Assessment Scale was used to assess the observational studies. All analyses were performed using STATA version 18.0. RESULTS: Eight studies were included in the meta-analysis. Compared with cesarean hysterectomy, PAS women undergoing conservative management showed lower estimated blood loss [WMD - 1623.83; 95% CI: -2337.87, -909.79], required fewer units of packed red blood cells [WMD - 2.37; 95% CI: -3.70, -1.04] and units of fresh frozen plasma transfused [WMD - 0.40; 95% CI: -0.62, -0.19], needed a shorter mean operating time [WMD - 73.69; 95% CI: -90.52, -56.86], and presented decreased risks of bladder injury [RR 0.24; 95% CI: 0.11, 0.50], ICU admission [RR 0.24; 95% CI: 0.11, 0.52] and coagulopathy [RR 0.20; 95% CI: 0.06, 0.74], but increased risk for endometritis [RR 10.91; 95% CI: 1.36, 87.59] and readmission [RR 8.99; 95% CI: 4.00, 12.21]. The incidence of primary or delayed hysterectomy rate was 25% (95% CI: 19-32, I2 = 40.88%) and the use of uterine arterial embolization rate was 78% (95% CI: 65-87, I2 = 48.79%) in conservative management. CONCLUSION: Conservative management could be an effective alternative to cesarean hysterectomy when women with PAS desire to preserve the uterus and are informed about the limitations of conservative management.

A Novel Approach for Conservative Management of Placenta Accreta Spectrum Disorder Cases: Experience of a Single Surgeon: PAS Disorders and Conservative Management.

Background: This study is aimed at evaluating the conservative surgical treatment of patients with placenta accreta spectrum (PAS) disorder and at presenting the experience of a single surgeon. Materials and Methods: This retrospective study included 245 patients with placenta previa accompanied by PAS disorders operated at a university hospital between June 2013 and December 2023. The diagnosis of PAS was made by a single perinatologist using a combination of transvaginal and transabdominal ultrasonography. All patients were operated with conservative surgical technique by the same surgeon. The demographic and clinical characteristics of the patients, the anesthesia and incision types used, and the details of the surgical technique were evaluated. Results: Of the patients, 165 were operated on at the scheduled time, 80 were operated on under emergency conditions, and 232 (94.69%) of them were operated on under spinal anesthesia. All patients were operated on with a Pfannenstiel incision followed by a transverse incision to the upper border of the placenta to enter into the uterus. An average of 0.52 units of red blood cells per patient was transfused to all patients. Spontaneous intra-abdominal bleeding developed in five patients, and surgical complications occurred in eight patients. No cesarean hysterectomy was performed, and no maternal mortality was detected in any of the cases. The mean time duration of surgery was 54.44 ± 11.37 (30-90) min, and the mean length of hospital stay was 1.71 ± 1.30 (1-9) days. Conclusions: We recommend this procedure as a novel technique and a robust and safe alternative to peripartum hysterectomy and other conservative surgical management procedures for cases with complete PP accompanied with PAS. This technique preserves the uterus as well as reduces blood loss, and transfusion requirement, and thus maternal morbidity and mortality in PAS cases.

The Soleymani and Collins Obstetric morbidity score (SaCOMS): A quantitative tool for measuring maternal morbidity from complex obstetric surgery such as placenta accreta spectrum (PAS).

It is currently very difficult to compare different management strategies for complex obstetric surgery, such as hysterectomy for severe Placenta Accreta Spectrum (PAS), as there is no widely accepted consensus for the classification of maternal surgical morbidity. Many studies focus on the amount of blood products transfused or admission to intensive care units (ICU). However, these are dependent on local policies and available resources. It also gives an incomplete representation of the entire 'patient journey' after they leave the operating room. Subsequent repeat procedures for lower urinary track damage is arguably worse from the woman's perspective than a short stay on an intensive care unit (ICU) for observation. We suggest a version of the Clavien-Dindo morbidity classification specific to obstetrics. Then employ it to build a quantitative morbidity score which aims to reflect the whole 'patient experience' including the post-operative pathway. We then demonstrate the utility of this system in a cohort of women with Placenta Accreta Spectrum (PAS). The Clavien-Dindo classification was modified to reflect obstetric procedures and a quantitative morbidity measure, the Soleymani and Collins Obstetric Morbidity Score (SaCOMS), was developed based on this. Both were then validated using a survey-based consultation of a panel of experts in PAS and retrospectively applied to a cohort of 54 women who underwent caesarean hysterectomy for PAS. Clinicians with expertise in PAS believe that the Modified Obstetric Clavien-Dindo classification system and the novel SaCOMS tool can improve assessment of maternal morbidity, and better reflect the 'patient experience'. Application of the classification system to a single-centre PAS cohort suggested that surgery by gynecologic-oncology surgeons may be associated with decreased incidence and cumulative morbidity outcomes for women with PAS, especially those with the most severe presentation. This study presents a clinically useful obstetric-specific classification system for surgical morbidity. SaCOMS also provides a quantitative reflection of the full patient- journey experienced as a result of surgical complications enabling a more patient-centered representation of morbidity.

Diagnosis of placenta accreta spectrum using ultrasound texture feature fusion and machine learning.

INTRODUCTION: Placenta accreta spectrum (PAS) is an obstetric disorder arising from the abnormal adherence of the placenta to the uterine wall, often leading to life-threatening complications including postpartum hemorrhage. Despite its significance, PAS remains frequently underdiagnosed before delivery. This study delves into the realm of machine learning to enhance the precision of PAS classification. We introduce two distinct models for PAS classification employing ultrasound texture features. METHODS: The first model leverages machine learning techniques, harnessing texture features extracted from ultrasound scans. The second model adopts a linear classifier, utilizing integrated features derived from 'weighted z-scores'. A novel aspect of our approach is the amalgamation of classical machine learning and statistical-based methods for feature selection. This, coupled with a more transparent classification model based on quantitative image features, results in superior performance compared to conventional machine learning approaches. RESULTS: Our linear classifier and machine learning models attain test accuracies of 87 % and 92 %, and 5-fold cross validation accuracies of 88.7 (4.4) and 83.0 (5.0), respectively. CONCLUSIONS: The proposed models illustrate the effectiveness of practical and robust tools for enhanced PAS detection, offering non-invasive and computationally-efficient diagnostic tools. As adjunct methods for prenatal diagnosis, these tools can assist clinicians by reducing the need for unnecessary interventions and enabling earlier planning of management strategies for delivery.

Predictive Value and Limitations of the Placenta Accreta Index: A Systematic Review.

Our systematic review highlights that multiparametric PAI score assessment is a consistent tool with high sensitivity and specificity for prenatal prediction for placenta accreta spectrum (PAS) in high-risk population with anterior placenta previa or low-lying placenta and prior cesarean deliveries. A systematic search was conducted on November 1, 2022, of MEDLINE via PubMed, Scopus, Web of Science Core Collection, Cochrane Library, and Google Scholar to identify relevant studies (PROSPERO ID # CRD42022368211). A total of 11 articles met our inclusion criteria, representing the data of a total of 1,044 cases. Women with PAS had an increased mean PAI total score, compared to those without PAS. Limitations of the PAI are most studies were conducted in developing countries in high-risk population which limit the global generalizability of findings. Heterogeneity of reported data did not allow to perform meta-analysis.

Lower Uterine Segment Corrugated Sutures in Hemorrhage during Cesarean Section because Previal and/or Placenta Accreta Spectrum: Case Reports Series and Literature Review.

OBJECTIVES: We present the original technique of compression hemostatic sutures on the lower uterine segment due to early postpartum hemorrhage during cesarean section, with a literature review. METHODS: A retrospective clinical case study was conducted at the tertiary perinatal center. Twelve patients had nine planned and three urgent cesarean sections due to antenatally verified placenta previa and/or placenta accreta spectrum and defined early postpartum hemorrhage > 1000 mL during cesarean section. As the use of uterotonics failed to produce any effect and hemorrhage persisted, compression sutures of the lower uterine segment were made by our own technique, as follows: below the hysterotomy, a horizontal corrugated suture is placed from the right to the left corner and after 2-3 cm vertically and backwards at several sites from the left to the right corner, where it is tightened. RESULTS: Seven patients had one cesarean section, three patients had two cesarean sections, and seven patients had pregnancy from the in vitro fertilization procedure in their history. There were six patients with placenta previa and six patients with anterior invasive placenta accreta or increta. Original hemostatic procedure was applied successfully in ten cases, and after placement of O'Leary suture and persistent bleeding in two cases. In this group, no hysterectomy was performed, and patients received blood transfusion of 440-880 mL. Three patients later had spontaneous pregnancies. CONCLUSION: Our own hemostatic method with a simple technique, fast learning, and minimal logistics contributes to successful management of this currently global problem of morbidly adherent placenta previa.

MR Imaging of Placenta Accreta Spectrum: A Comprehensive Literature Review of the Most Recent Advancements.

This article delves into the latest MR imaging developments dedicated to diagnosing placenta accreta spectrum (PAS). PAS, characterized by abnormal placental adherence to the uterine wall, is of paramount concern owing to its association with maternal morbidity and mortality, particularly in high-risk pregnancies featuring placenta previa and prior cesarean sections. Although ultrasound (US) remains the primary screening modality, limitations have prompted heightened emphasis on MR imaging. This review underscores the utility of quantitative MR imaging, especially where US findings prove inconclusive or when maternal body habitus poses challenges, acknowledging, however, that interpreting placenta MR imaging demands specialized training for radiologists.

Risk Factors for Postpartum Hemorrhage in Severe Pre-Eclampsia: A Retrospective Single-Centre Study of 1953 Cases.

BACKGROUND Severe pre-eclampsia (sPE) and postpartum hemorrhage (PPH) in pregnancy have serious impact on maternal and fetal health and life. Co-occurrence of sPE and PPH often leads to poor pregnancy outcomes. We explored risk factors associated with PPH in women with sPE. MATERIAL AND METHODS This retrospective study included 1953 women with sPE who delivered at the Women's Hospital of Nanjing Medical University between April 2015 and April 2023. Risk factors for developing PPH in sPE were analyzed, and subgroups were analyzed by delivery mode (cesarean and vaginal). RESULTS A total of 197 women with PPH and 1756 women without PPH were included. Binary logistic regression results showed twin pregnancy (P<0.001), placenta accreta spectrum disorders (P=0.045), and placenta previa (P<0.001) were independent risk factors for PPH in women with sPE. Subgroup analysis showed risk factors for PPH in cesarean delivery group were the same as in the total population, but vaginal delivery did not reduce risk of PPH. Spinal anesthesia reduced risk of PPH relative to general anesthesia (P=0.034). Vaginal delivery group had no independent risk factors for PPH; however, magnesium sulfate (P=0.041) reduced PPH incidence. CONCLUSIONS Women with twin pregnancy, placenta accreta spectrum disorders, placenta previa, and assisted reproduction with sPE should be alerted to the risk of PPH, and spinal anesthesia should be preferred in cesarean delivery. Magnesium sulfate should be used aggressively in women with sPE; however, the relationship between magnesium sulfate and PPH risk needs further investigation.

Placenta Accreta Spectrum: A Comprehensive Review of Guidelines.

Importance: Placenta accreta spectrum (PAS) represents a range of disorders characterized by abnormal placental invasion and is associated with severe maternal morbidity and mortality. Objective: The aim of this study was to review and compare the most recently published major guidelines on the diagnosis and management of this potentially life-threatening obstetric complication. Evidence Acquisition: A descriptive review of guidelines from the American College of Obstetricians and Gynecologists, the Royal Australian and New Zealand College of Obstetricians and Gynecologists, the International Society for Abnormally Invasive Placenta, the Royal College of Obstetricians and Gynecologists, the International Federation of Gynecology and Obstetrics, and the Society of Obstetricians and Gynecologists of Canada on PAS disorders was carried out. Results: There is a consensus among the reviewed guidelines regarding the definition and the diagnosis of PAS using specific sonographic signs. In addition, they all agree that the use of magnetic resonance imaging should be limited to the evaluation of the extension to pelvic organs in case of placenta percreta. Moreover, American College of Obstetricians and Gynecologists, Royal College of Obstetricians and Gynecologists, International Federation of Gynecology and Obstetrics, and the Society of Obstetricians and Gynecologists of Canada agree that screening for PAS disorders should be based on clinical risk factors along with sonographic findings. Regarding management, they all highlight the importance of a multidisciplinary team approach and recommend delivery by elective cesarean section at a tertiary center with experienced staff and appropriate resources. Routine preoperative ureteric stenting and occlusion of pelvic arteries are universally not recommended. Moreover, hysterectomy following the delivery of the fetus, expectant management with placenta left in situ, and conservative management in case of focal disease and desired fertility are all considered as acceptable treatment options. The reviewed guidelines also suggest some measures for intraoperative and postoperative hemorrhage control and recommend prophylactic administration of antibiotics. Methotrexate after expectant management is unanimously discouraged. On the other hand, there is no common pathway with regard to the optimal timing of delivery, the recommended mode of anesthesia, the preferred skin incision, and the effectiveness of the delayed hysterectomy approach. Conclusions: PAS disorders are mainly iatrogenic conditions with a constantly rising incidence and potentially devastating consequences for both the mother and the neonate. Thus, the development of uniform international practice protocols for effective screening, diagnosis, and management seems of paramount importance and will hopefully drive favorable pregnancy outcomes.

Placental T2WI MRI-based radiomics-clinical nomogram predicts suspicious placenta accreta spectrum in patients with placenta previa.

BACKGROUND: The incidence of placenta accreta spectrum (PAS) increases in women with placenta previa (PP). Many radiologists sometimes cannot completely and accurately diagnose PAS through the simple visual feature analysis of images, which can affect later treatment decisions. The study is to develop a T2WI MRI-based radiomics-clinical nomogram and evaluate its performance for non-invasive prediction of suspicious PAS in patients with PP. METHODS: The preoperative MR images and related clinical data of 371 patients with PP were retrospectively collected from our hospital, and the intraoperative examination results were used as the reference standard of the PAS. Radiomics features were extracted from sagittal T2WI MR images and further selected by LASSO regression analysis. The radiomics score (Radscore) was calculated with logistic regression (LR) classifier. A nomogram integrating Radscore and selected clinical factors was also developed. The model performance was assessed with respect to discrimination, calibration and clinical usefulness. RESULTS: A total of 6 radiomics features and 1 clinical factor were selected for model construction. The Radscore was significantly associated with suspicious PAS in both the training (p < 0.001) and validation (p < 0.001) datasets. The AUC of the nomogram was also higher than that of the Radscore in the training dataset (0.891 vs. 0.803, p < 0.001) and validation dataset (0.897 vs. 0.780, p < 0.001), respectively. The calibration was good, and the decision curve analysis demonstrated the nomogram had higher net benefit than the Radscore. CONCLUSIONS: The T2WI MRI-based radiomics-clinical nomogram showed favorable diagnostic performance for predicting PAS in patients with PP, which could potentially facilitate the obstetricians for making clinical decisions.

[Placenta accreta: a retrospective descriptive study of 46 patients treated in the Obstetrics and Gynaecology Department of the Farhat Hached University Hospital in Sousse, Tunisia]. / Placenta accreta: étude descriptive rétrospective de 46 cas pris en charge au Service de Gynécologie-obstétrique du Centre Hospitalier Universitaire Farhat Hached de Sousse, Tunisie.

Placenta accreta is a rare but serious placental attachment abnormality. The aim of this study is to analyze the epidemiological, clinical, para-clinical and evolutionary features of placenta accreta, to investigate the therapeutic management and to assess maternal and neonatal morbidity and mortality. We conducted a retrospective, descriptive study of patients with histologically confirmed placenta accreta in the obstetrics and gynaecology department of the Farhat Hached University Hospital in Sousse, over a 4-year period from 1st January 2015 to 31st December 2019. The epidemiological, clinical, paraclinical, therapeutic and evolutionary data were collected from patients´ medical records and operative reports. In our series, we identified 46 cases of placenta accreta. The average age of our patients was 35±4.61 years. Each of our patients had a scarred uterus. The average term of delivery was 34 weeks of amenorrhoea and the mode of delivery was caesarean section for all our patients. First-line hysterectomy was performed in 40 patients and conservative treatment in 6. Sixteen patients developed maternal complications. No maternal death was observed. Placenta accreta is a rare condition associated with significant maternal and foetal morbidity.
