Placenta accreta is a severe pregnancy complication and is currently the most common indication for peripartum hysterectomy. It is becoming an increasingly common complication mainly due to the increasing rate of cesarean delivery. Main risk factor for placenta accreta is a previous cesarean delivery particularly when accompanied with a coexisting placenta previa. Antenatal diagnosis seems to be a key factor in optimizing maternal outcome. Diagnosis can be achieved by ultrasound in the majority of cases. Women with placenta accreta are usually delivered by a cesarean section. In order to avoid an emergency cesarean and to minimize complications of prematurity it is acceptable to schedule cesarean at 34 to 35 weeks. A multidisciplinary team approach and delivery at a center with adequate resources, including those for massive transfusion are both essential to reduce neonatal and maternal morbidity and mortality. The optimal management after delivery of the neonate is vague since randomized controlled trials and large cohort studies are lacking. Cesarean hysterectomy is probably the preferable treatment. In carefully selected cases, when fertility is desired, conservative management may be considered with caution. The current review discusses the epidemiology, predisposing factors, pathogenesis, diagnostic methods, clinical implications and management options of this condition.

BACKGROUND The prevalence of Placenta Accreta Spectrum(PAS) is increasing rapidly linked with the cesarean rate increase worldwide, creating a threatening condition from severe postpartum hemorrhage to various maternal morbidities. The socio-economic imbalance, geographical, qualification, and specialty variations of the previous cesarean delivery healthcare facilities resulted in assessment and management difficulties. OBJECTIVE To assess variations of prior cesarean delivery healthcare facilities on pregnancy outcomes on current PAS with Placenta Previa. METHODS This retrospective study was conducted in a tertiary referral center from Nov.2015 to Nov.2020 in central China. Healthcare facilities were classified by geographical, hospital grading, ownership, and specialty variations. The primary outcome was postpartum hemorrhage(PPH), secondary outcomes included Placenta Percreta and maternal-fetal morbidities. RESULTS In total, 252 patients were enrolled, 58(23%) patients had Placenta Accreta, 131(52%) had Placenta Increta and 63(25%) had Placenta Percreta. The overall incidence of PPH was 47.2%(119 out of 252). As the administrative geographical level becoming smaller and more distant, PPH incidence climbed up: province-level(10, 32.3%), prefecture-level(65, 48.5%), county-level(30, 42.3%), and rural township(14, 82.5%), P for trend= 0.019. The odds of PPH in rural township clinics was 5.84(P=0.03, 95%CI 1.18~28.77) compared to the province-level hospitals. Similarly, when hospital grades declined, PPH incidence raised: tertiary(26, 39.4%), secondary(28, 43.8%), primary(14, 38.9%) and unclassified(51, 59.3%), P for trend= 0.047. Unclassified hospitals had 2.16(P= 0.046, 95%CI 1.02~4.61) times odds of PPH compared to tertiary medical centers. PPH showed no statistical significance based on ownership or specialty variations. Also, Placenta Percreta increased when geographical location shifted from urban to rural: three (9.7%) from province-level, 34(25.6%) from prefecture-level, 18(25.4%) from county-level and eight(47.1%) from rural township clinics, P= 0.04, P for trend =0.018. Patients with previous rural township clinics cesarean delivery had a 7.49 times risk((P=0.011, 95%CI 1.59~35.19) of developing Placenta Percreta compared with province-level hospitals. CONCLUSIONS Healthcare facilities variations of the previous cesarean delivery have upcoming impacts on subsequent pregnancy. The tendency of experiencing adverse maternal outcomes is more significant with prior cesarean in the rural township clinics and unclassified hospitals. The findings call for physicians’ alertness, persistent efforts in urban-rural disparity reduction, and measures to achieve equitable management.

Abstract Background Placenta accreta is a potentially life-threatening obstetric condition that requires a multidisciplinary approach to management. The incidence of placenta accreta has increased and seems to parallel the increasing cesarean delivery rate. Women at greatest risk of placenta accreta are those who have myometrial damage caused by a previous cesarean delivery with either an anterior or posterior placenta previa overlying the uterine scar. Diagnosis of placenta accreta before delivery allows multidisciplinary planning in an attempt to minimize potential maternal or neonatal morbidity and mortality. Aim of the Work To compare between alpha-fetoproteine as biological marker & ultrasound & Doppler findings for prenatal predication of morbid adherent placentation in anterior placenta on scar of previous cesarean section. Patients and Methods The current study is a prospective cohort study, conducted at a tertiary center: Ain Shams University Maternity Hospital during the period between February 2018 and April 2019,where 150 pregnant women having placenta previa covering scar of previous uterine surgery had been recruited from the outpatient obstetrics clinic or emergency room and admitted to antepartum inpatient high risk service, but 50 patients were dropped out due to loss in follow up because of emergency antepartum haemorrhage & C.S., others escaped follow up. Results The results of the current study showed a significant association between all criteria of the 3DPD with multislice view and presence of placental adherence, need for added surgical steps, CS hysterectomy and bladder injury with sensitivity 83% & specificity 57%, PPV 76%, NPV 66%. Conclusion The current study suggests that AFP assay, it isn't good test alone as regards its sensitivity &specificity &its level of accuracy 55% as compared to 2D &3D power doppler with multislice view, so it is unreliable test alone for antenatal diagnosis of morbidly adherent placenta.

Spectrum Disorders

Introduction: Placenta accreta spectrum disorders are among the leading causes of maternal morbidity and mortality and their prevalence is likely to increase in the future. The risk of placenta accreta spectrum disorders is highest in cases of placenta previa overlying a previous cesarean section scar. Few studies have evaluated placenta accreta spectrum disorders in Portugal. The aim of this study was to review the cases of placenta accreta spectrum overlying a cesarean section scar managed in a Portuguese tertiary center over the last decade.Material and Methods: Retrospective, cross-sectional study, with data collected from hospital databases. Only cases with histopathological confirmation of placenta accreta spectrum were included.Results: During the study period, 15 cases of placenta accreta spectrum overlying a cesarean section scar were diagnosed (prevalence 0.6/1000). All cases were diagnosed antenatally. A transverse cesarean section was present in all cases; 13 were managed by a scheduled multidisciplinary approach, while two required emergent management. Total or subtotal hysterectomy was performed in 12 cases. There were no cases of maternal or neonatal death. Histopathological evaluation confirmed nine cases of placenta accreta, three cases of placenta increta and three cases of placenta percreta.Discussion: Early antenatal diagnosis is important for a programmed multidisciplinary management of these cases, which may reduce potential morbidity and mortality and ensure better obstetric outcomes.Conclusion: This case series of placenta accreta spectrum overlying a cesarean section scar reports the reality of a tertiary-care perinatal center in Portugal, in which no maternal or neonatal mortality due to placenta accreta spectrum was registered over the last decade; this may be attributed to prenatal diagnosis and a coordinated multidisciplinary team approach.

Threatening Situation

Placenta accreta spectrum (PAS) refers to the range of pathologic adherence of the placenta, including placenta increta, placenta percreta, and placenta accreta. PAS disorder is a maternal and fetal life-threatening situation due to the high risk of intrapartum uncontrollable bleeding. The common described risk factors are the placenta previa and history of Caesarean section (CS) [1]. We herein report our experience with five patients referred to our department for suspected PAS. These patient were selected for targeted prepartum ultrasound assessment due to their history of multiple C-sections. PAS risk increase with the number of previous CS and could reach7% [2]. In Nicaragua , the rate of c-section in obstetrical practice is still high and approximating 40% in some centers. Uterine wall dehiscence result in locally defective decidualisation and abnormal placental adherence with important trophoblastic invasion in a subsequent pregnancy [3]. We still believe that this disorder is preventable if we “go back” a little to obstetrical good practices. Dramatic situations can be avoided by selecting suspected PAS on ultrasound or MRI to be referred. PAS is the commonest cause of intrapartum hysterectomy and must be managed always in specialized centers with multidisciplinary team approach.

In the last three to four decades, the increasing caesarean delivery rate has contributed to several fold increment in the incidence of placenta accreta spectrum disorders globally. Placenta accreta spectrum with its subtypes (accreta, increta and percreta) is one of the devastating obstetric complications. As a result, it is the commonest indication for peripartum hysterectomy and common cause of severe maternal morbidity. However, in recent years, there is a growing interest in and practice of expectant management either to minimize emergency hysterectomy related maternal complications or to preserve the fertility potential of a woman with an intact uterus. A large body of observational research findings has demonstrated the success rate of expectant management in many of well selected cases. Similarly, the experience on delayed hysterectomy was encouraging in order to have less hemorrhage. For the best success of placenta accreta spectrum management, multidisciplinary team approach, antenatal diagnosis and managing such cases in a hospital with center of excellence has been strongly recommended. This literature review provides a robust synthesis of up-to-date knowledge and practice on the challenges and successes of placenta accreta spectrum disorders management. The currently practiced management options in the high and middle income countries are also summarized under seven categories. Therefore, the purpose of this review was to shed light on the applicability of the PAS disorder management modalities in our setup.

Background: The study aims to evaluate the effect of cervical length and the transcervical placental thickness measurement at 28-30 weeks gestation in predicting the risk of antepartum haemorrhage (APH) and emergency preterm caesarean delivery (CD) in women with placenta previa accreta.Methods: A prospective cohort study conducted at Aswan university hospital from June 2015 to April 2017 included one hundred and five cases diagnosed as placenta previa accreta by transvaginal ultrasound (TVS) between 28-30 weeks gestation were divided into three groups according to their cervical length which measured by TVS: group I (cervical length >30 mm), group II (cervical length 20-30 mm) and group III (cervical length <20 mm). Also, placental thickness measurement was done. Cervical length and placental thickness and correlated with the clinical outcome regarding to gestational age at delivery, APH, emergency CD due to massive haemorrhage, the need for blood transfusion and caesarean hysterectomy.Results: APH and emergency CD due to massive bleeding were significantly higher in cases with short cervical length and thick placenta. APH occurred in 6 cases (15%) in group I, 14 cases (40%) in group II and 24 cases (80%) in group III, (p=0.0001). Emergency CD in group I was performed in 5 cases (12.5 %), 12 cases (34.3 %) in group II and 24 cases (80%) in group III, (p =0.0001). The incidence of APH was higher in thick placenta [6 cases (42.9 %) compared to none with thin placenta in group I (p=0.001), 13 cases (68.4%) compared to one case (6.2%) in group II (p=0.0001) and 21 cases (100%) compared to 3 cases (33.3%) in group III (p=0.0001)].Conclusions: Short cervical length and increased placental thickness may predict the risk of APH and emergency preterm CD in patients with placenta accreta.
