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...

OBJECTIVE: To clarify whether distinguishing between the uterine isthmus and cervix can improve the accuracy of diagnosing placenta previa at term. METHODS: A multicenter prospective observational study was conducted among pregnant women with suspected placenta previa at 20-24 weeks' gestation. Subjects were divided into the open isthmus group and closed isthmus group. The accuracy of diagnosing placenta previa at term was compared between the 2 groups. RESULTS: We screened 9,341 patients, and 53 (0...

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...

Intrauterine globe-shaped metreurynter tamponade has been used for some time to treat massive postpartum hemorrhage (PPH). More recently, the Bakri balloon has come into use to treat PPH. It is made of silicon, possesses a drainage lumen, and has a sausage-like spindle shape. The aim of the present study was to investigate the clinical usefulness of Bakri balloon tamponade for massive PPH. Subjects in the present study comprised 5 patients with uterine atony, 3 with placenta previa, and 2 with low-lying placenta...

Amniotic fluid embolism (AFE) is a disorder with a high mortality rate. We present a case of AFE with cardiac arrest during the cesarean section who recovered sequela. A 28-year-old woman was diagnosed as low lying placenta and planned to undergo cesarean section in 38th gestational week. She had atypical genital bleeding in 32nd gestational weeks and she received emergency cesarean section under general anesthesia. After expulsion of her fetus, she lost many blood. We suspected obstetric DIC and started therapy immediately, but cardiac arrest occurred suddenly...

OBJECTIVES: The purpose of this study was to evaluate the association between first-trimester sonographic findings and morbidly adherent placenta at delivery. METHODS: We conducted a retrospective review of all first-trimester sonographic examinations from pregnancies that underwent third-trimester sonography for placenta previa or low-lying placenta between September 1997 and October 2011. Only women with a prior cesarean delivery were included. Transabdominal and transvaginal images from these first-trimester studies were reviewed for the following sonographic parameters: distance from the inferior border of the gestational sac to the external cervical os, location of the decidua basalis, presence of anechoic areas, uterine-bladder interface irregularity, and smallest anterior myometrial thickness...

Cornual pregnancy is uncommon among ectopic pregnancies. A diagnosis of cornual pregnancy remains challenging, and rupture of a cornual pregnancy causes catastrophic consequence due to massive bleeding. In very rare circumstances, cornual pregnancies can result in a viable fetus. We report a case of a 24-year-old primigravida who presented to us with complaints of decrease fetal movements at 37(+5) weeks. Ultrasound revealed a single live intrauterine fetus with anterior low lying placenta with severe oligohydramnios (amniotic fluid index = 1...

BACKGROUND: We examined the clinical significance of pregnancies complicated by velamentous cord insertion (VCI) associated with other umbilical cord/placental abnormalities. METHODS: Data were collected from 168 deliveries complicated by VCI and from 16,797 unaffected controls. All placentae were screened identically by trained staff. In this study, we examined the presence of excessively long umbilical cord (longer than 70 cm), vasa previa, single umbilical artery, circumvallate placenta, succenturiate placenta, lobed placenta, placenta previa, low lying placenta and placenta accrete as the other umbilical cord/placental abnormalities...
