"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...

Conservative management (leaving the placenta in situ) for abnormally invasive placenta (AIP: accreta, increta, percreta) has been repeatedly discussed in AOGS (1, 2). Delayed hemorrhage and infection are important adverse events. Especially, delayed hemorrhage required hysterectomy 3-9 months post-cesarean section in 22-58% of cases (1, 3), often performed as an emergency surgery (1, 3). Although delayed hysterectomy is not always associated with massive bleeding, a magnetic resonance imaging (MRI) showed marked gadolinium enhancement (marked blood flow) in the placental-bed-myometrium on post-cesarean day 34 (4), suggesting that hemorrhage may be serious during delayed hysterectomy at least up to one month post-cesarean...

BACKGROUND: Morbidly adherent placentation now complicates approximately 1 in 500 pregnancies. Our group and others have demonstrated that antenatal diagnosis of invasive placentation and team-based delivery reduce severe morbidity. Ultrasound and magnetic resonance imaging (MRI) are both employed in the antenatal evaluation of pregnancies with suspected placenta increta/percreta. Accurate diagnosis in this context is essential to direct resources appropriately. Ultrasound methods, including colour and power Doppler, are the mainstays of screening at-risk women, whereas MRI is reserved for diagnostic purposes because of its cost and limited accessibility...

OBJECTIVES: To retrospectively review the MRI findings of placenta percreta and identify those helpful for differentiation from non-placenta percreta. MATERIALS AND METHODS: The MRI images of 21 patients with a preliminary diagnosis of placental adhesive disorder scanned between 2005 and 2014 were evaluated. Radiologists blinded to the final diagnosis evaluated six previously described MRI findings of placenta adhesive disorder. The sensitivity, specificity, accuracy, negative predictive value (NPV), and positive predictive value (PPV) of MRI for the diagnosis of placenta percreta were also calculated...

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...

Placenta percreta is a rare condition that presents a risk of massive intraoperative hemorrhage. To decrease maternal morbidity in such cases, conservative management was recently adopted as an option. Nevertheless, severe morbidity occurs in 42% of cases. In addition, the clinical course of conservative management remains unclear. We encountered a case of placenta percreta that was successfully treated by conservative management without complications or other clinical interventions. Serial magnetic resonance imaging (MRI) was performed to investigate the natural course of conservative management of placenta percreta...

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...

BACKGROUND: Determining the depth of villous invasiveness before delivery is pivotal in planning individual management of placenta accreta. We have evaluated the value of various ultrasound signs proposed in the international literature for the prenatal diagnosis of accreta placentation and assessment of the depth of villous invasiveness. OBJECTIVE: We undertook a PubMed and MEDLINE search of the relevant studies published from the first prenatal ultrasound description of placenta accreta in 1982 through March 30, 2016, using key words "placenta accreta," "placenta increta," "placenta percreta," "abnormally invasive placenta," "morbidly adherent placenta," and "placenta adhesive disorder" as related to "sonography," "ultrasound diagnosis," "prenatal diagnosis," "gray-scale imaging," "3-dimensional ultrasound", and "color Doppler imaging...

Cesarean deliveries in patients with placenta accreta often are accompanied by life-threatening bleeding and sometimes death. A novel, multidisciplinary approach that uses uterine embolization after cesarean delivery recently has been advocated; however, embolization in the radiology department requires transfer of postoperative patients, which could increase maternal mortality and morbidity. In a case of severe placenta accreta, we planned a stepwise treatment, including cesarean delivery without separation of the placenta followed by intraoperative uterine arterial embolization in a hybrid operating room, followed by hysterectomy a few weeks after cesarean delivery...

Spontaneous Uterine rupture is associated with massive intra-peritoneal bleed which can be fatal if not recognized. We report a case of 32 year old multigravida at 28 weeks of gestation with history of liver cysts, previous caesarean and uterine curettage, who presented with acute abdominal pain and tenderness; ultrasound revealed placenta percreta. CT abdomen showed haemoperitoneum. The patient underwent emergency caesarean hysterectomy due to uterine rupture at the cornual site.

OBJECTIVE: Advances in prenatal imaging techniques have led to an increase in the diagnosis of caesareans scar pregnancy (CSP). However, antenatal counselling when CSP is diagnosed is challenging and the current evidence mainly derived from small series reporting high rates of adverse maternal outcomes. The aim of this study was to ascertain the performance of prenatal ultrasound in anticipating the natural history of CSP introducing a new sonographic sign, the cross-over sign (COS). METHODS: Retrospective analysis of early first trimester (6-8 weeks of gestation) ultrasound images of women with morbidly adherent placenta (MAP) treated in the third trimester of pregnancy...

Placental adhesion disorder (PAD) comprises placenta accreta, increta and percreta lesions; these are classified according to the depth of uterine invasion. Although PAD is considered a rare condition, its incidence has increased 10-fold in the last 50 years. Ultrasound is the primary imaging modality for the assessment of the placenta and in the majority of cases, it is sufficient for diagnosis; however, when ultrasound findings are suspicious or inconclusive, MRI is recommended as an adjunct imaging technique...
