“…In particular the close monitoring of these patients is needed [21]. It seems that the presence of an amniotic sheet is not associated with an increased risk of amniotic sheets in subsequent pregnancies [21].…”

The obstetrical ultrasound may identify the protrusion of the uterine surface or placental area into the amniotic cavity. The differential diagnosis of this pathology with uterine adhesions, septate uterus, circumvallate placenta, amniotic band or amniotic sheet can be sometimes difficult. The purpose of the pictorial essay is to exemplify the presence of the amniotic sheet and circumvallate placenta in routine obstetrics screening of all trimesters of pregnancy.

“…Amniotic sheets form when an existing synechia comes in contact with the expanding fetal membranes of the chorion and amnion. These membranes then fold around the synechia, creating a linear four-layered structure comprising two outer amnion layers sandwiching two inner chorion layers, with a variable amount of stretched endometrium or scar tissue (Fig 8) (13,(20)(21)(22). Although these ILEs comprise synechiae with amniotic sheets (ie, the folded chorion and amnion), they are almost universally referred to as synechiae in the literature.…”

“…The fetus is exposed to only the smooth surface of the amniotic membrane; this is in stark contrast to cases of amniotic bands (discussed in greater detail later), in which the fetus is exposed to the extraembryonic coelomic space (13,22). Although the appearance of synechiae changes little during pregnancy, these adhesions may be difficult to identify later during the pregnancy or at delivery-probably owing to rupture or displacement during fetal growth and uterine expansion (20)(21)(22). Rarely, synechiae are compressive and compartmentalize the uterus owing to the scar and associated membranes extending tightly across the uterus (Fig 9) (24).…”

Intrauterine linear echogenicity (ILE) is a common ultrasonographic finding in the gravid uterus and has variable causes and variable maternal and fetal outcomes. Correctly categorizing ILE during pregnancy is crucial for guiding surveillance and advanced imaging strategies. Common causes of ILE include membranes in multiple gestations, uterine synechiae with amniotic sheets, and uterine duplication anomalies. Less common causes include circumvallate placenta, chorioamniotic separation, and hemorrhage between membranes. Amniotic band syndrome is a rare but important diagnosis to consider, as it causes severe fetal defects. Imaging findings enable body stalk anomaly, a lethal defect, to be distinguished from amniotic bands, which although destructive are not necessarily lethal. This review describes the key imaging findings used to differentiate the various types of ILE in pregnancy, thus enabling accurate diagnosis and appropriate patient counseling. Online supplemental material is available for this article. RSNA, 2018.

“…The true prevalence of intrauterine adhesions is difficult to establish, because the condition is rare in the general population and often asymptomatic. Estimates of the prevalence range from 1.5% as an incidental finding at hysterosalpingogram to 21.5% of women with a history of postpartum uterine curettage (6). Intrauterine adhesions typically result from intrauterine trauma associated with a surgical procedure, although infection may play a minor contributing role.…”

<p>Amniotic band sequence (ABS) describes highly variable spectrum of congenital anomalies that occur in association with amniotic bands. İntrauterine synechiae is a condition in which scar tissue develops within the uterine cavity. We aim to present a case of ABS and a case of intrauterine synechiae and compare their ultrasonographic findings. Ultrasonography revealed contraction ring in the right groin area of the first fetus but second fetus was healthy. The diagnosis of ABS is based upon the presence of characteristic structural findings on prenatal ultrasound or postnatal physical examination. The diagnosis of intrauterine adhesions is based upon visualization of intrauterine adhesions either directly by hysteroscopy or indirectly by other imaging studies. The floor of the intrauterine adhesions is widely and lateral of the uterine cavity and occurs from four layers while the amniotic band is a thin layer and forms fluctuations in the amniotic fluid. Amniotic bands may cause variable spectrum of congenital anomalies whereas intrauterine adhesions do not increase the probability of fetal anomaly because it is out of the amniotic cavity.</p>

Effect of an Amniotic Sheet on Pregnancy Outcomes

Abstract: An amniotic sheet is associated with an increase in poor obstetric outcomes. Therefore, close monitoring of pregnancies after diagnosis is required.
