Obstetric ultrasound

INTRODUCTION: The antenatal diagnosis of open spina bifida (OSB), a neural tube defect, is predominantly made at the second trimester morphology scan by ultrasound detection of structural abnormalities resulting from the associated Chiari II malformation. Evidence has emerged suggesting that these structural abnormalities can be detected earlier, by examination of the posterior fossa as part of the first trimester nuchal translucency scan. In particular, absence of the intra-cranial translucency (IT) of the fourth ventricle has shown promise as a diagnostic marker of OSB, although the sensitivity and specificity of this finding varies widely in the literature...

PURPOSE: Pfeiffer syndrome (PS) is an autosomal dominant disorder caused by mutations in FGFR1 and FGFR2 genes. Given its wide range of clinical expression and severity, early prenatal diagnosis is difficult and genetic counseling is desirable. We report a literature review of all prenatal diagnosis of PS and a case report, with a focused description of ultrasound findings. METHODS: After literature search, we selected 14 studies of antenatal diagnosis of PS. Prenatal ultrasound findings, outcome, maternal and obstetrical data and genetic tests were recorded and analyzed...

BACKGROUND: Congenital complete heart block is a life-threatening condition which is highly associated with autoimmune and connective tissue disorders. Presence of maternal autoantibodies for associated conditions increases the risk of delivering a child with congenital complete heart block, however, less than a half of all women with such antibodies are symptomatic even after delivery. Mortality rate is highest during the neonatal period (45 %) and about two-thirds of all cases will require permanent pacing at some point in their lives...

OBJECTIVES: The purpose of this study was to (1) describe and compare two obstetric Mayan populations in Guatemala, the Tz'utujil and the Kachiquel and (2) evaluate possible associations of demographics, wood fuel use, and obesity with pregnancy/newborn outcomes. DESIGN: This cross-sectional study interviewed participants at the time of routine obstetric ultrasounds at three institutions in Santiago Atitlán and one institution in San Lucas Tolimán. Data were collected from January 2010 to May 2013...

Ventriculomegaly (VM) is a nonspecific finding on fetal imaging. Identification of the specific etiology is important as it affects prognosis and may even change the course of current or future pregnancies. In this review we will focus on the application of fetal MRI to demonstrate intracranial hemorrhage (ICH) and ischemic brain injury as opposed to other causes of VM. MRI is able to identify the specific etiology of ventriculomegaly with much more sensitivity and specificity than ultrasound and should be considered whenever VM is identified on obstetric ultrasound...

OBJECTIVE: Methotrexate is routinely used worldwide for medical treatment of clinically stable women with tubal ectopic pregnancies. This is despite the lack of robust evidence to show its superior effectiveness over expectant management. The aim of our multicentre randomised trial study was to compare the success rates of methotrexate with placebo for the conservative treatment of tubal ectopic pregnancies. METHODS: The study was multicentre; it took place in three UK early pregnancy units between January 2006 and June 2014...

Balanced translocation is a common structural chromosomal rearrangement in humans. Carriers can be phenotypically normal but have an increased risk of pregnancy loss, fetal death, and the transmission of chromosomal abnormalities to their offspring. Existing prenatal screening technologies and diagnostic procedures fail to detect balanced translocation, so genetic counseling for carriers remains a challenge. Here, we report the characteristics of chromosomal reciprocal translocation in 3807 amniocentesis cases...

BACKGROUND: Due to the importance of cardiovascular dysfunction and advances in the development and use of non-invasive cardiac output (CO) monitoring devices, there is a growing interest in their use in the obstetric population. The aim of this study was to compare two commercially available, non-invasive CO monitors in the assessment of heart rate (HR), stroke volume (SV), CO, cardiac index (CI) and total peripheral resistance (TPR) in an obstetric population. METHODS: This was a prospective, comparative study including two groups...

Placental masses are uncommonly identified at the time of obstetric ultrasound evaluation. Understanding the pathologies presenting as placental masses is key for providing a differential diagnosis and guiding subsequent management, which may include additional imaging with magnetic resonance (MR) imaging. Potential benign entities include chorioangiomas and teratomas. Larger chorioangiomas can cause fetal cardiovascular issues from volume overload. Placental mesenchymal dysplasia has an association with fetal anomalies and detailed fetal evaluation should be performed when it is suspected...

Vaginal bleeding is a common event in early pregnancy, with 20-40% of pregnancies affected. Prompt diagnosis and management of bleeding is important, both to reduce morbidity and to avoid excessive emotional distress. This was a prospective study of an educational programme aimed at Obstetrics and Gynaecology BST trainees in the National Maternity Hospital, Dublin. The educational programme consisted of didactic lectures, and simulation and practical sessions. A questionnaire reviewing early pregnancy complications was used to assess participant knowledge...

Objective This study aims to evaluate pregnancy outcomes in patients with spontaneous and iatrogenic chorioamniotic separation diagnosed by ultrasound after 17 weeks. Methods This is a retrospective cohort study of women with a singleton pregnancy who were diagnosed with chorioamniotic separation (n = 106) after 17 weeks' gestation from January 2000 to January 2013. Patients with chorioamniotic separation were compared with a group of patients who had obstetric ultrasounds without a diagnosis of chorioamniotic separation...

OBJECTIVES: The aim of this study was to correlate clinical findings of anal sphincter defects and function with a sonographic diagnosis of significant sphincter defects. METHODS: This is an observational cross-sectional study on women seen 6 to 10 weeks after primary repair of obstetric anal sphincter injuries (OASIs). All patients underwent a standardized interview including the St Mark incontinence score, a digital rectal examination, and 3-/4-dimensional transperineal ultrasound imaging...

Objective: To explore the application value of assisted laparoscopic ultrasound in myomectomy. Methods: One hundred and fifty six patients who underwent myomectomy in Beijing Obstetrics and Gynecology Hospital from 2011 to 2013 were enrolled.The patients were randomly divided into laparoscopic ultrasound guided group (n=57), laparoscopic group (n=54) and open resection group (n=45). The patients were followed up to calculate the residue and recurrence rates of uterine fibroids by vaginal ultrasound at 6th month and 12th-18th month after the operation...
