Placenta accreta

Dilek Uysal, Hakan Cokmez, Cetin Aydin, Tolga Ciftpinar
Postpartum haemorrhage is the most important cause of maternal morbidity and mortality, especially when all conservative measures, including syntometrine oxytocin and Bakri balloons have failed to accomplish haemostasis and expeditious surgical procedures, such as uterine artery ligation and emergency peripartum hysterectomy (EPH) are required. This retrospective study analysed 31 cases of EPH performed between January 2007 and January 2016 in the Department of Gynecology and Obstetrics of Izmir Ataturk Teaching and Research Hospital...

Historically, the evolutionary origins of menstruation have been based on two theories: the ability to eliminate infectious agents carried to the uterus with spermatozoa and the comparative conservation of energy with menstruation compared to its absence. In the menstruating species, more recent theories have identified spontaneous decidualization as the key adaptive mechanism. Spontaneous decidualization is seen as a mechanism to provide the mother with protection from the invasive characteristics of the embryo...

OBJECTIVE: To investigate whether women who were surgically treated for retained products of conception (RPOC) by either suction curettage or hysteroscopy are at risk for recurrent RPOC on their subsequent pregnancies. STUDY DESIGN: Retrospective analysis of 442 women surgically treated for RPOC following delivery or abortion by suction curettage (N = 63, 14.3%) or hysteroscopy (N = 379, 85.7%). Information on subsequent pregnancies and their outcomes was available for 161 (36...

BACKGROUND: Parturients with abnormally adherent placentas present anesthetic challenges that include risk-stratification, management planning and resource utilization. The labor and delivery unit may be remote from the main operating room services. METHODS: Division chiefs of North American obstetric anesthesiology services were surveyed about their practices and management of parturients with an abnormally adherent placenta. RESULTS: Eighty-four of 122 chiefs, representing 103 hospital sites, responded to the survey (response rate 69%)...

Background: Cesarean section (CS) is an independent risk factor for placenta accreta. Some researchers think that the timing of primary cesarean delivery is associated with placenta accreta in subsequent pregnancies. The aim of this study was to investigate the risk of placenta accreta following primary CS without labor, also called primary elective CS, in a pregnancy complicated with placenta previa. Methods: A retrospective, single-center, case-control study was conducted at Peking University Third Hospital...

OBJECTIVE:  We aimed to evaluate the relationship between hyperglycosylated human chorionic gonadotropin (hCG-H) and placenta accreta spectrum (PAS) in the second and third trimesters of pregnancy. STUDY DESIGN:  This was a case-control study of PAS and controls. hCG-H was measured in the second and third trimesters of pregnancy in women with pathologically confirmed cases of PAS and in gestational age-matched controls without PAS. We compared serum hCG-H levels in cases and controls, calculated summary statistics for diagnostic accuracy, and used receiver operating characteristic (ROC) curves to define an optimal cut-point for diagnosis of PAS using hCG-H...

Placenta accreta is a pathologic condition of early placentation that has been studied by clinicians and pathologists for nearly 100 years. The main effect is a loss of the normal plane of cleavage from the uterine wall, resulting in massive haemorrhage when attempts are made at removing the placenta manually at delivery. Excessive remodelling of the radial and arcuate arteries in the invasive forms of placenta accreta spectrum increases the risk of complications (Jauniaux et al., AJOG, 2018;218:75-87).

OBJECTIVE: Placenta accreta is clinically associated with maternal uterine scar. Our objective was to investigate the biochemical contribution of maternal scarring to hyperinvasive trophoblast. We hypothesized that trophoblast over-invasion in placenta accreta is associated with aberrant invasion-site signaling of growth and angiogenic factors known to be involved in wound healing and promotion of cell invasion through the epithelial to mesenchymal cellular program. DESIGN: Cross-sectional series...

For many years, modifications of the uterine extracellular matrix (ECM) during gestation have not been considered as critical for successful canine (Canis lupus familiaris) pregnancy. However previous reports indicated an effect of free-floating blastocysts on the composition of the uterine ECM. Here, the expression of selected genes involved in structural functions, cell-to-cell communication and inhibition of matrix metalloproteinases were targeted utilizing qPCR and immunohistochemistry. We found that canine free-floating embryos affect gene expression of FN1, ECM1 and TIMP4...

OBJECTIVES: The objective of our study was to determine the impact of laser therapy for twin-to-twin transfusion syndrome (TTTs) on subsequent pregnancies. METHODS: This was a monocentric retrospective observational study. Women treated by laser fetoscopy for TTTs were asked to answer a postal questionnaire about subsequent pregnancies. The primary outcome was fecundity (number of pregnancies and time to pregnancy). We also assessed pregnancy complications, birth weight, and gestational age at delivery...

OBJECTIVE: Online-to-offline is a new model for emergent medical service with the ability to connect care providers with patients on instant basis. This study aims to evaluate maternal and neonatal outcomes in patients with placenta accreta spectrum managed by an online-to-offline care model. METHODS: Starting from January 1, 2015, management of patients with placenta accreta spectrum was changed from standard care model into an online-to-offline care model through "Wechat" in Guangzhou Medical Centre for Critical Obstetrical Care...

OBJECTIVES: To examine the evidence regarding the effectiveness and safety of endovascular interventional modalities for haemorrhage control in abnormal placentation deliveries. METHODS: MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched from inception to July 2017. Blood loss volume was regarded as the primary endpoint. Other important results are described. Random and fixed effects models were used for the meta-analysis...

OBJECTIVE: To (a) evaluate the risk for placenta accreta following primary cesarean section (CS), in regard to the stage of labor, the cesarean section was taken (elective prelabor vs. unplanned during labor); and (b) investigate whether the association between placenta accreta and maternal and neonatal complications is modified by the type of the primary CS. STUDY DESIGN: In a population-based retrospective cohort study, we included all singleton deliveries occurred in Soroka University Medical Center between 1991 and 2015, of women who had a history of a single CS...

Case: A 39-year-old woman presented with a genital hemorrhage at 5 weeks of gestation after an artificial cycle double frozen-thawed embryo transfer. She was diagnosed with a cervical heterotopic pregnancy. Although hormone supplementation was discontinued to terminate the pregnancy at 5 weeks of gestation, the intrauterine and cervical gestational sacs continued to develop. Outcome: The cervical gestational sac was surgically removed and the intrauterine pregnancy continued uneventfully, except for vasa previa...
