PURPOSE OF REVIEW: Abnormal placentation is a clinical condition seen increasingly in the pregnant population. It is associated with significant morbidity and mortality, which may be mitigated through robust multidisciplinary care for these patients. The role of maternal critical care for these patients has largely been ignored in the literature. RECENT FINDINGS: Advances in pharmacological management of bleeding with recent publications of large multicentre trials in addition to new technologies in the management of massive obstetric haemorrhage (MOH) have revolutionized the management of abnormal placentation...

INTRODUCTION: Complete placenta previa (CPP) is one of the most problematic types of abnormal placenta, which is further complicated by placenta accreta or percreta that can unexpectedly lead to catastrophic blood loss, infection, multiple complications, emergency hysterectomy, and even death. The present study aimed to assess the efficacy of random placenta margin incision in controlling intraoperative and total blood loss during cesarean section for CPP women. METHODS: A prospective cohort study, including a total of 100 consecutive pregnant women with CPP, was performed at a tertiary university-affiliated medical center between March 2016 and July 2017...

A 33-year-old G2P1 was referred to our hospital due to placenta accreta. During perioperative preparations, the patient was diagnosed with having a peripartum cardiomyopathy. The patient underwent caesarean hysterectomy at 36 weeks with an associated 2 L blood loss. Haemodynamic maintenance and stabilisation during the operation were challenging, with the combinations of fluid therapy, blood transfusions as well as vasoactive, antifibrinolytic and haemostatic drug. Postoperatively, the patient was managed in the intensive care unit and was subsequently transferred to intermediate care after less than 24 hours' observation...

BACKGROUND: Magnetic resonance imaging is reported to have good sensitivity and specificity in the diagnosis of placenta accreta spectrum disorders, and is often used as an adjunct to ultrasound. But the additional utility of obtaining an MRI to assist in the clinical management of patients with placenta accreta spectrum disorders, above and beyond the information provided by ultrasound, is unknown. OBJECTIVE: We aimed to determine whether magnetic resonance imaging provides data that may inform clinical management by changing the sonographic diagnosis of placenta accreta spectrum disorders...

RATIONALE: Placenta accreta is the main cause of severe obstetric postpartum hemorrhage (PPH) and hysterectomy. Several hemostatic techniques have been performed in patients with placenta accreta to prevent PPH and reserve fertility. Abdominal aorta and pelvic arteries balloon occlusion are the only techniques which could be performed before cesarean section (CS) in patients who want to keep the fetus and reserve fertility. However, abdominal aorta and pelvic arteries balloon occlusion might lead to severe complications such as formation and rupture of pseudoaneurysm, angiorrhexis, etc...

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...

REVIEW
John Jarrell
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...

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...
