INTRODUCTION: A vasa previa (VP) refers to aberrant chorionic vessels which can either connect the chorionic plate to a velamentous cord (type I) or a succenturiate or accessory lobe to the main placental mass (type II). METHODS: We performed retrospective cohort study of 32 singleton pregnancies diagnosed with VP. The levels of maternal serum alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG) and unconjugated estriol (uE3) were measured at 15-18 weeks as part of the triple test screening for Trisomy 21...

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...

BACKGROUND: The incidence of placenta accreta (PA) has increased from 0.8 to 3.0 in 1000 pregnancies, driven by increased rates of cesarean deliveries (32.2% in 2014) of births in the United States. The average blood loss for a delivery complicated by PA ranges from 2000 to 5000 mL, frequently requiring substantial transfusion medicine support. We report our own institutional multidisciplinary approach for managing such patients, along with transfusion medicine outcomes, in this setting over a 5-year period...

The aim of current study was to determine women´s maternal asthma in pregnancy, delivery and birth outcomes. Using a retrospective cohort design, data of 580 pregnant women were gathered form a large teaching hospital in Tehran, Iran. The medical records of pregnant women who had attended this hospital between 2009 and 2011 were assessed. Data of delivery and birth outcomes were gathered by observation and medical records of women. Multiple logistic regression and adjusted odds ratio (OR) were used to assess the independent association of asthma and outcomes...

This prospective study was conducted to assess the rate of resolution of second trimester placenta previa in women with anterior placenta and posterior placenta, and that in women with and without previous cesarean section. In this study, placenta previa was defined as a placenta lying within 20 mm of the internal cervical os or overlapping it. We recruited 183 women diagnosed with previa between 20(+0) weeks and 25(+6) weeks. They were grouped according to their placenta location (anterior or posterior) and history of cesarean section...

INTRODUCTION: Ogilvie's Syndrome or Acute Colonic Pseudo-Obstruction (ACPO) is a rare condition characterized by massive dilatation of the colon in the absence of mechanical obstruction. About 10% of all reported cases are related to Obstetric and Gynaecological procedures, Caesarean section being the commonest associated factor. Acute intestinal dilatation, if not treated, may lead to perforation and faecal peritonitis with consequent high morbidity and mortality. MATERIALS AND METHODS: An electronic literature searches were performed in PubMed, EMBASE, Google scholar and hand searches for relevant references were included without any language restriction...

BACKGROUND: Approximately 1/3 of all deliveries in the United States are via cesarean. Previous research indicates weight gain during pregnancy is associated with an increased risk of cesarean delivery. It remains unclear, however, whether and to what degree weight gain between deliveries (i.e., inter-delivery weight gain) is associated with cesarean delivery in a subsequent pregnancy following a vaginal delivery. OBJECTIVES: To determine whether inter-delivery weight gain is associated with an increased risk of intrapartum cesarean delivery following a vaginal delivery...

Objective. To determine maternal morbidity in women with placenta previa managed with prediction of morbidly adherent placenta (MAP) by ultrasonography. Methods. A retrospective cohort study was undertaken comprising forty-one women who had placenta previa with or without risk factors for MAP. Women who had all three findings (bladder line interruption, placental lacunae, and absence of the retroplacental clear zone) were regarded as high suspicion for MAP and underwent cesarean section followed by hysterectomy...

BACKGROUND: Several epidemiological studies have determined that assisted reproductive techniques (ART) can increase the risk of placenta previa. To date, only a meta-analysis has been performed for assessing the relationship between placenta previa and ART. This meta-analysis was conducted to estimate the association between placenta previa and ART in singleton and twin pregnancies. METHODS: A literature search was performed in major databases PubMed, Web of Science, and Scopus from the earliest possible year to April 2017...

BACKGROUND: Incidental leiomyosarcoma (LMS) is a rare diagnosis in pregnancy or in the puerperium. To our knowledge, this is the first case reported in the literature of incidental LMS after cesarean hysterectomy for morbidly adherent placenta. CASE: We present a case of a cesarean hysterectomy performed for a suspected morbidly adherent placenta in a patient with three prior cesarean deliveries, an anterior placenta previa and a fundal fibroid. Subsequent pathology identified a LMS on final specimen...

Abnormally invasive placentation is becoming more common with a recent increase in cesarean sections and maternal age, among other risk factors. Ultrasonography is the first line-imaging, but it can be difficult to diagnose when limiting factors are present. Failure to recognize this serious placental abnormality precludes us from making the appropriate plan for the delivery and consequently can lead to fatal results. In this report, we present a case in which magnetic resonance imaging was used to diagnose posterior placenta increta missed by multiple sonographic examinations in a patient with previous myomectomies, and we also include a review of the literature on this topic...
