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.

Abstract Objectives We aimed to assess the performance of ultrasound (US) and magnetic resonance imaging (MRI) signs for antenatal detection of placenta accreta spectrum (PAS) disorders in women with placenta previa (placental edge ≤2 cm from the internal uterine orifice, ≥260/7 weeks’ gestation) with and without a history of previous Caesarean section. Methods Single center prospective observational study. US suspicion of PAS was raised in the presence of obliteration of the hypoechoic space between uterus and placenta, interruption of the hyperechoic uterine-bladder interface and/or turbulent placental lacunae on color Doppler. All MRI studies were blindly evaluated by a single operator. PAS was defined as clinically significant when histopathological diagnosis was associated with at least one of: intrauterine balloon placement, compressive uterine sutures, peripartum hysterectomy, uterine or hypogastric artery ligature, uterine artery embolization. Results A total of 39 women were included: 7/39 had clinically significant PAS. There were 6/18 cases of PAS with anterior placenta: hypoechoic space interruption and placental lacunae were the most sensitive sonographic signs (83%), while abnormal hyperechoic interface was the most specific (83%). On MRI, focal myometrial interruption and T2 intraplacental dark bands showed the best sensitivity (83%), bladder tenting had the best specificity (100%). 1/21 women with posterior placenta had PAS. There was substantial agreement between US and MRI in patients with anterior placenta (κ=0.78). Conclusions US and MRI agreement in antenatal diagnosis of clinically significant PAS was maximal in high-risk women. Placental lacunae on ultrasound scan and T2 intraplacental hypointense bands on MRI should trigger the suspicion of PAS.
