Introduction Basal plate myometrium (BPMYO), the pathological presence of myometrial fibers in the basal plate, is a common finding on pathological examination of the placenta, yet its clinical correlates are not well studied. As myometrial fibers are frequently located in proximity to poorly converted maternal spiral arteries, our objective was to determine whether BPMYO is associated with hypertensive disorders of pregnancy (HDP), a well-known clinical sequela of abnormal maternal artery remodeling. Methods This case-control study included women who delivered a live-born singleton gestation whose placentas were sent for pathological examination...

Postpartum hemorrhage causes 25% of all maternal deaths worldwide and is the leading cause of maternal morbidity and mortality following vaginal or caesarean delivery. Every year, postpartum hemorrhage is estimated to cause approximately 125 000 maternal deaths and is associated with morbidity among 20 million women. It is caused by several obstetric conditions, including uterine atony and placental problems such as placenta accreta spectrum disorders, trauma, and lacerations. Several techniques are known to prevent postpartum hemorrhage, including uterine cavity tamponade, uterine artery ligation, uterine artery embolization, pre-cesarean prophylactic balloon catheterization, uterine compression sutures, hypogastric artery ligation, and hysterectomy...

Major obstetric hemorrhage is the leading cause of maternal morbidity and mortality. In rare cases, life-threatening hemorrhage in pregnant women may result from abnormal adherence of placenta. Three grades of abnormal placental attachment are defined according to the depth of invasion: placenta accreta, placenta increta, and placenta percreta. An important risk factor for placenta abnormal adherence of placenta is placenta previa in the presence of a uterine scar. The increased prevalence of cesarean section, uterine surgery, and increasing parturient age and parity have led to an increased incidence of abnormal placentation, from one in 2,500 a quarter century ago, to one in 533 deliveries currently...

INTRODUCTION: Abnormally invasive placenta involves abnormal adherence of the placenta to the myometrium and is associated with severe pregnancy complications such as blood transfusion and hysterectomy. Knowledge of outcomes has been limited by small sample sizes and a focus on maternal rather than neonatal outcomes. This study uses population-level data collected over 10 years to investigate maternal and neonatal outcomes and trends in incidence of abnormally invasive placenta (also known as placenta accreta, increta and percreta)...

Although a history of first-trimester recurrent spontaneous abortion (FRSA) is regarded as a risk factor in antenatal care, the characteristic of subsequent pregnancy outcome is not clearly elucidated. Here, a retrospective analysis was performed on the clinical data of 492 singleton pregnant women. 164 of them with the history of FRSA were enrolled in study group, compared to 328 deliveries without the history of FRSA. For maternal outcomes, patients in the study group delivered earlier with mean gestational age and the incidences of cesarean section and postpartum hemorrhage were higher compared to the control group...

The placenta is a remarkable organ, it serves as the interface between the mother and the fetus. Proper invasion of trophoblast cells is required for a successful pregnancy. Previous studies have found that the adhesion molecule integrin β4 plays important roles during trophoblast cell invasion. Here, we found that the overall birth rate of the MARVELD1 knockout mouse is much lower than that of the wild-type mouse (P<0.001). In E18.5 MARVELD1 knockout mice, we observed an over-invasion of trophoblast cells, and indeed, the pregnant mice had a partial placenta accreta phenotype...

BACKGROUND: The incidence of placenta accreta (PA) has increased from 0.8 to 3.0 in 1000 pregnancies, driven by increased rates of cesarean deliveries (32.2% in 2014) of births in the United States. The average blood loss for a delivery complicated by PA ranges from 2000 to 5000 mL, frequently requiring substantial transfusion medicine support. We report our own institutional multidisciplinary approach for managing such patients, along with transfusion medicine outcomes, in this setting over a 5-year period...

PURPOSE: To confirm reduced expression of soluble fms-like tyrosine kinase 1 (sFlt-1) in accreta/increta. METHODS: Formalin-fixed tissue sections from 11 peripartum hysterectomies with invasive placentation and 5 controls were stained for sFlt-1. Stain intensity was scored in selected 100× microscopic fields. We compared sFlt-1 expression in invasive areas among cases, non-invasive areas among cases and areas from control placentas. RESULTS: Chorionic villi displayed significantly decreased sFlt-1 expression in invasive areas of cases compared to control placentas (p = 0...
