Advanced hysteroscopic surgery (AHS) is a vitally important technique in the armamentarium for the management of many day-to-day clinical problems, such as menorrhagia, surgical excision of uterine myomata and septa in the management of female infertility, hysteroscopic excision of chronically retained products of conception (placenta accreta), and surgical removal of intramural ectopic pregnancy. In today's climate of accountability, it is necessary that gynecologists take a more active role in assuring the quality of their work...

PURPOSE: The aim of this study was to prenatally predict placenta accreta in posterior placenta previa using magnetic resonance imaging (MRI). METHODS: This retrospective study was approved by the Institutional Review Board of our hospital. We identified 81 patients with singleton pregnancy who had undergone cesarean section due to posterior placenta previa at our hospital between January 2012 and December 2016. We calculated the sensitivity and specificity of several well-known findings, and of cervical varicosities quantified using magnetic resonance imaging, in predicting placenta accreta in posterior placenta previa...

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...

We thank Dr. Matsubara and colleagues(1) for commenting on our study, "Patient selection for later delivery timing with suspected previa-accreta."(2) We particularly appreciate the emphasis on individualized patient care, and that access (or lack thereof) to a tertiary center with experience in managing abnormally invasive placenta (AIP) is of paramount importance when considering delivery timing.

Placenta accreta spectrum is a complex obstetric complication associated with high maternal morbidity. It is a relatively new disorder of placentation, and is the consequence of damage to the endometrium-myometrial interface of the uterine wall. When first described 80 years ago, it mainly occurred after manual removal of the placenta, uterine curettage, or endometritis. Superficial damage leads primarily to an abnormally adherent placenta, and is diagnosed as the complete or partial absence of the decidua on histology...

BACKGROUND: Placenta accreta (PA), a severe complication during delivery, is closely linked with massive hemorrhage which could endanger the lives of both mother and baby. Moreover, the incidence of PA has increased dramatically with the increasing rate of cesarean deliveries in the past few decades. Therefore, studies evaluating the effects of different perioperative managements based on different modalities in the treatment of PA are necessary. Among the numerous treatment measures, prophylactic abdominal aortic balloon occlusion (AABO) in combination with cesarean section for PA seems to be more advantageous than others...

BACKGROUND: Ultrasound (US) is the primary imaging modality for the diagnosis of placenta accreta, but it is not sufficiently accurate. MRI morphologic criteria have recently emerged as a useful tool in this setting, but their analysis is too subjective. Recent studies suggest that gadolinium enhancement may help to distinguish between the stretched myometrium and placenta within a scar area. However, objective MRI criteria are still required for prenatal diagnosis of placenta accreta...

We performed an impact study on the introduction of routine placement of internal iliac artery balloon catheters for the management of haemorrhage during caesarean section in women with placenta accreta. We identified 11 women, with prenatally diagnosed placenta accreta/increta/percreta before this change in practice, who acted as controls, and 30 women who had iliac artery balloons placed. The balloons were inflated in 27 cases. The median (IQR [range]) intra-operative blood loss was 1100 (800-2600 [500-6000]) ml in controls, compared with 1000 (600-2513 [400-15000]) ml in women with iliac artery balloons (p = 0...
