Spontaneous rupture of previous uterine scar due to placenta percreta in early second trimester is a very rare and serious complication. A27-year fourth gravida, second para with previous two lower segment caesarean sections, presented at 17-week of twin pregnancy with acute abdominal pain. Ultrasonograghy revealed 17-week diamniotic-dichorionic twin pregnancy with alive fetuses. The placenta of the first twin was anterior, low lying covering the internal os and penetrating through the entire thickness of the lower uterine wall laterally...

INTRODUCTION: Vasa previa (VP) is defined as a condition in which the fetal blood vessels, unsupported by the placenta or the umbilical cord, run through the membranes of the lower uterine segment. It is associated with a high risk of stillbirth by exsanguination. This study aimed to assess the clinical context of diagnosis of VP in order to elaborate a strategy for its prenatal diagnosis and to improve its obstetrical and neonatal outcomes. MATERIAL AND METHODS: This historical cohort study covered the period from January 1, 2011 to December 31, 2015...

Endocervical varices are a rare cause of obstetrical hemorrhage. Usually presenting in the second and third trimesters, bleeding varices often require pregnancy termination or indicated preterm birth via cesarean delivery. Our patient experienced variceal hemorrhage at 12 weeks' gestation in a dichorionic twin pregnancy conceived through in vitro fertilization. A low-lying placenta resolved at 19 weeks followed by variceal regression at 22 weeks' gestation. Endocervical varices causing first-trimester hemorrhage may regress with resolution of a coexisting low placental implantation, permitting planned vaginal delivery, despite progressive hemodynamic changes of pregnancy...

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...

BACKGROUND: Mesenchymal stromal cells (MSC) are multipotent adult stem cells with immunomodulatory properties. They uniquely express HLA class I antigen at a low level, and do not express HLA class II. Hence, for allogeneic administration, donor to recipient matching is not required; yet a prolonged chimeric state does not occur. Contrary to haematopoietic stem cell transplantation, cytotoxic drug therapy is not required to harvest, or administer, cells. Key Messages: MSC are obtained from marrow, adipose tissue or placenta...

This prospective cohort study was conducted in Arash Women's Hospital between August 2014 and August 2015 to define the relationship between caesarean section scar and placental implantation and migration. Seven hundred and thirty women with one previous birth (caesarean section or vaginal delivery) and a singleton pregnancy underwent three ultrasound examinations for placental evaluation at 11-14, 20 and 34 weeks gestation. Previous caesarean section was related to the increased odds of anterior placental implantation but no relation was seen between low-lying placenta or placenta praevia and previous caesarean...

A velamentous umbilical cord is characterized by membranous umbilical vessels at the placental insertion site that are prone to compression and rupture, especially when they are located in the membranes covering the cervical os (vasa praevia). The velamentous insertion of the umbilical cord, with a reported incidence of 1% in singleton pregnancies and 15% in monochorionic twin gestations, has been associated with obstetric complications: fetal growth restriction, prematurity, congenital anomalies, low Apgar scores, fetal bleeding with acute fetal distress and placental retention...

The perinatal mortality rate of vasa previa is high if it is not prenatally diagnosed. In this report, a case of vasa previa diagnosed prenatally is presented. Antepartum hemorrhage at 24 weeks of gestation prompted a close investigation of the uterine cervix, internal os, and placenta. We detected a low-lying bilobed placenta with umbilical cord insertion in the lower uterine segment. Furthermore, one of the connecting vessels of the bilobed placenta passed directly above the internal os. Vasa previa was suspected and confirmed with color Doppler and MRI...

OBJECTIVE: To assess the applicability of trial of labor in cases of low-lying placenta. METHODS: In this observational cohort study, we collected data from the women with low-lying placenta delivered at our hospital between April 2012 and December 2015. Low-lying placenta was diagnosed when the length from the placental lowest edge to the internal cervical os (placenta-os distance) was 0-20 mm at 36 gestational weeks. Planned mode of delivery for each case was determined by patient's preference...

PURPOSE: To present a case report on the successful management of a low-lying placenta and aplastic anemia. Aplastic anemia is a rare but serious disorder that is often characterized by severe pancytopenia. Because of the rarity of aplastic anemia, a pregnancy complicated by it is rarely encountered by obstetricians. Moreover, placenta previa (low-lying placenta) complicated by aplastic anemia has not been previously reported. MATERIALS AND METHODS: The authors present the first reported case of placenta previa with aplastic anemia in a patient who had undergone a previous cesarean delivery...
