“…SGA and CLD incidences were higher in the circumvallate placenta group than in controls. As to the association between circumvallate placenta and SGA, fetal growth restriction has been speculated to be caused by placental insufficiency due to a marginal infarct, hemorrhage, and hemosiderin deposition, in addition to a hypoplastic placenta [ 2 , 11 ]. It has also been suggested that prolonged vaginal bleeding during pregnancy causes hemosiderin deposition in the placenta and chorion, resulting in diffuse chorioamniotic hemosiderosis, and that the fetus may swallow bloody amniotic fluid and thereby develop CLD [ 12 , 13 ].…”

“…Bey et al [ 14 ] say that when vaginal bleeding occurs in the 2nd trimester despite a normally implanted placenta, circumvallate placenta should be included in the differential diagnosis. Several studies have reported that circumvallate placenta can be diagnosed based on ultrasonographic abnormalities in placental appearance [ 2 – 5 , 15 ]. McCarthy et al [ 5 ] reported diagnostic criteria based on an irregular, uplifted placental edge (rounded placental margin) or a marginal shelf or rim (thin or sheet-like placental edge).…”

“…McCarthy et al [ 5 ] reported diagnostic criteria based on an irregular, uplifted placental edge (rounded placental margin) or a marginal shelf or rim (thin or sheet-like placental edge). Suzuki [ 2 ] described measurement of placental thickness (thickest part ≥3.0 cm) as being useful for circumvallate placenta screening. Arlicot et al [ 15 ] recently reported that circumvallate placenta was diagnosed by 3-dimensional sonographic imaging showing a circumferential depression with a thick peripheral ring in the placenta.…”

“…However, few circumvallate placenta cases have been reported. The diagnosis is difficult during pregnancy and circumvallate placenta is often detected only by placental examination after delivery [ 2 – 5 ].…”

Aims. To analyze the pregnancy outcomes of circumvallate placenta retrospectively and to predict circumvallate placenta during pregnancy based on its clinical features. Methods. The pregnancy outcomes of 92 women with circumvallate placenta who delivered live singletons at a tertiary care center between January 2000 and September 2012 were compared with those of 9057 controls. Results. Women with circumvallate placenta were associated with higher incidences of preterm delivery (64.1%), placental abruption (10.9%), emergency cesarean section (45.6%), small-for-gestational age (36.9%), neonatal death (8.9%), neonatal intensive care unit admission (55.4%), and chronic lung disease (33.9%). When vaginal bleeding during the second trimester and premature chemical rupture of membranes (PCROM) were both used as predictive factors for circumvallate placenta, the sensitivity was 28.8% and specificity was 99.9%. Conclusion. With circumvallate placenta, pregnancy outcomes were poor and had characteristic clinical manifestations. In women with both vaginal bleeding and PCROM during pregnancy, circumvallate placenta should be strongly suspected.

“…On examination, there is a characteristic white ring around the surface of the placental disk that is comprised of a double layer of amnion and chorion with fibrin and necrotic villi. It is predisposed to abnormal separation and commonly presents with 2nd trimester vaginal bleeding, being diagnosed via ultrasound or after delivery [23]. Pregnancy complications are common and include oligohydramnios, small for gestational age (SGA) neonates, abruption, and intrauterine fetal demise (IUFD) [24][25][26].…”

A detailed discussion of normal placental development and physiology is beyond the scope of this chapter and is discussed in other chapters. Instead, this chapter will focus on an overview of congenital placental abnormalities and the obstetrical complications that can arise. The goal of this chapter is to delineate the real-world implications of placental abnormalities and provide the reader with a basis for understanding the other chapters that will delve into microbiology, genomics, immunohistochemistry, and biochemistry of the placenta. The focus of this chapter will be on the developmental anomalies and this chapter will not discuss acquired anomalies (e.g., chorioamnionitis, amnion nodosum, metastatic tumors, and umbilical cord true knots). As the intention of this chapter is to focus on the etiopathogenesis of abnormal placentation, it is not intended to instruct the medical management of the described conditions, and therefore the discussions of management will be brief. The information provided is intended for general knowledge only and is not intended for use in diagnosing or treating a health problem or disease without consultation with a qualified healthcare provider. This chapter is not a substitute for professional medical advice, or treatment for specific medical conditions.

BackgroundThe aim of this extended review of multicenter case series is to describe the prenatal ultrasound features and pathogenetic mechanisms underlying placental and umbilical cord anomalies and their relationship with adverse perinatal outcome. From an educational point of view, the case series has been divided in three parts; Part 1 is dedicated to placental abnormalities.MethodsMulticenter case series of women undergoing routine and extended prenatal ultrasound and perinatal obstetric care.ResultsPrenatal ultrasound findings, perinatal care, and pathology documentation in cases of placental pathology are presented.ConclusionsOur case series review and that of the medical literature confirms the ethiopathogenetic role and involvement of placenta abnormalities in a wide variety of obstetrics diseases that may jeopardize the fetal well‐being. Some of these specific pathologies are strongly associated with a high risk of poor perinatal outcome.

Antenatal screening for circumvallate placenta

Abstract: The current results suggest that measurement of placental thickness is useful for screening for circumvallate placenta.
