BACKGROUND: Placenta previa, one of the most severe obstetric complications, carries an increased risk of intraoperative massive hemorrhage. Several risk factors for intraoperative hemorrhage have been identified to date. However, the correlation between birth weight and intraoperative hemorrhage has not been investigated. Here we estimate the correlation between birth weight and the occurrence of intraoperative massive hemorrhage in placenta previa. MATERIALS AND METHODS: We included all 256 singleton pregnancies delivered via cesarean section at our hospital because of placenta previa between 2003 and 2015...

AIM: To evaluate the role of magnetic resonance imaging (MRI) for diagnosis and therapeutic planning in patients with abnormal placentation (AP). MATERIALS AND METHODS: Overall, 168 consecutive patients with suspected placenta previa and AP were referred for MRI before caesarean section (CS). The ability of MRI to properly detect and assess abnormal placentation was correlated with findings at CS, which were considered the reference standard diagnostic tool. For each patient, MRI was used to determine whether the AP was suitable for complete/incomplete delivery, hysterectomy, or conservative treatment...

"Morbidly adherent placenta" is a term that describes the continuum of placenta accreta, increta, and percreta. The incidence of this type of abnormal placentation has increased significantly over recent decades. The reason is probably multifactorial but, partly, because of factors such as the increasing number of cesarean births. Women at greatest risk are those who have myometrial damage caused by a previous cesarean birth, with either anterior or posterior placenta previa overlying the uterine scar. This condition poses significant risks of morbidity and/or mortality to the pregnant woman and her fetus...

This study was carried out to explore associations between assisted reproductive technology (ART) and maternal and neonatal outcomes compared with similar outcomes following spontaneously conceived births. We conducted a retrospective cohort study of pregnancies conceived by ART (N = 2641) during 2006-2014 compared to naturally conceived pregnancies (N = 5282) after matching for maternal age and birth year. Pregnancy complications, perinatal complications and neonatal outcomes of enrolled subjects were investigated and analysed by multivariate logistic regression...

AIM: During cesarean section (CS) for placenta previa (PP), the size/area/portion of the lower uterine segment occupied by the placenta may affect the bleeding amount and the subsequent need for a blood transfusion (BT). We propose a new concept, indiscernible edge total PP (IEPP), when vaginal ultrasound does not discern the lower placental edge because the placenta covers the visible lower segment. We characterized IEPP, focusing on its allogeneic BT requirement. METHODS: We classified PP (n = 307) into four types: marginal, partial, discernible edge total PP (DEPP) and IEPP: internal ostium (os)-placental edge distance measurable or unmeasurable on vaginal ultrasound in DEPP or IEPP, respectively...

PURPOSE OF REVIEW: Placental implantation abnormalities (PIAs) comprise a large group of disorders associated with significant maternal, fetal, and neonatal morbidity. RECENT FINDINGS: Risk factors include prior uterine surgery/myometrial scarring and the presence of placenta previa with or without prior cesarean delivery. Newly identified risk factors include previous prelabor cesarean delivery and previous postpartum hemorrhage. PIAs contribute substantially to preterm birth with prematurity rates ranging from 38 to 82%...

OBJECTIVE: Müllerian anomalies are associated with increased risk of miscarriage, intrauterine growth restriction (IUGR) and preterm birth. While a commonly implicated cause is restricted expansion of endometrial cavity, alternatively it could be due to abnormal placentation. We sought to examine clinical and histopathologic factors associated with preterm delivery in women with Müllerian anomalies. STUDY DESIGN: One hundred and eleven singleton pregnancies in 85 women were analyzed retrospectively...

Major obstetric hemorrhage is a challenge for anesthesiologists because it remains responsible for over 10% of maternal deaths in high-income countries. A standardized multidisciplinary management, described in locally validated protocols and based on international guidelines is mandatory to prevent these deaths. The first difficulty relies on the systematic underestimation of the bleeding. Collection bags must be used to facilitate the diagnosis and therefore rapid management. The etiologies in antenatal or postpartum must be well-known in order to be treated adequately...

Obstetric hemorrhage remains a leading cause of maternal mortality with more than 140,000 deaths annually worldwide. Abnormal placentation has increased to become the most common diagnosis requiring massive blood transfusion in obstetrics, with uterine atony a close second. At our institution, as well as nationwide, there has been a steady increase in pregnancies complicated by abnormal placentation, including accreta, increta, and percreta. Providers at our facility created the New England Center for Placental Disorders in May 2015 to address these complex patients...

Appropriate placentation is critical to maternal and fetal outcomes. Abnormal placentation, including placenta previa and morbidly adherent placenta, is increasing in incidence and is associated with multiple risk factors including advanced maternal age and history of prior cesarean delivery. Magnetic resonance imaging (MRI) is increasingly used in assessing the type and extent of abnormal placentation, often leading to modifications in surgical approach. Here, we review the MRI features and appropriate reporting of placenta previa and the placenta accreta spectrum...
