AIM: To show imaging results from application of four-dimensional (4D) ultrasound lightening technique (HDlive™) in clinical obstetrics practice. METHODS: Normal and abnormal fetuses at second and third trimester of pregnancy undergoing routine scan with 4D HDlive™ (5DUS) in the rendering mode are described. Realistic features of fetal structures were provided by 5DUS in the rendering mode. Normal anatomy as well as pathology like cleft lip, hypoplastic face, micrognathia, low-set ears, corpus callosum, arthrogryposis, aortic arch, left congenital diaphragmatic hernia are highlighted in this study...

OBJECTIVE: The aim of the study was to identify primiparous pregnant women with a higher risk for obstetric anal sphincter injuries (OASIS) based on obstetric characteristics (risk factors). STUDY DESIGN: In the retrospective case control study primiparous women were examined using endoanal ultrasonography (EUS) for OASIS identification 6-12 weeks after delivery. Obstetric characteristics for OASIS were collected from the mothers' medical records. The univariate analysis of maternal (age at delivery, maternal height, weight, BMI), infant (length, weight and head circumference) and birth (pregnancy duration, labour and delivery duration, episiotomy, vacuum extraction and oxytocin augmentation) risk factors, Pearson correlations and information gain were carried out...

BACKGROUND: The immunoglobulin (Ig) G avidity index (AI) is useful to detect primary cytomegalovirus (CMV) infection. However, because IgG matures with time, this index is not useful to detect a primary infection, unless measured at an appropriate time. OBJECTIVES: We aimed to clarify the difference between using IgG AI and IgM positivity according to the stage of pregnancy to identify congenital CMV infection risk. STUDY DESIGN: We collected the serum samples from 1115 pregnant women who underwent maternal screening for primary infection (n = 956) and were referred to our hospital because of CMV IgM positivity (n = 155) or had abnormal fetal ultrasonography findings (n = 4)...

OBJECTIVE: Describe tools designed to predict preterm birth in asymptomatic high-risk pregnancy and determine their predictive value. METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: Obstetric history particularly spontaneous preterm birth identifies a population at risk for preterm birth for the current pregnancy (LE3). This risk is related to the number of prior preterm birth and is even higher than the term of the prior event is more premature and that the event concerns the last pregnancy (LE3)...

Morbidly adherent placentation (MAP) is a condition in which the placenta is abnormally attached to the uterine myometrium. MAP is a complication of pregnancy that can cause significant morbidity to the mother and fetus and therefore early diagnosis is crucial in its management and prevention of adverse outcomes. Ultrasonography remains the primary diagnostic tool for MAP, with magnetic resonance imaging (MRI) serving as a secondary diagnostic modality. Elastography is a relatively new concept in ultrasound based imaging, which has found application in several fields of medicine, including obstetrics, primarily for evaluation of the firmness of cervical tissue in a preterm labour setting...

OBJECTIVE: To evaluate feasibility and initial outcomes of fetoscopic tracheal occlusion for severe diaphragmatic hernia compared with a historical cohort who had not received fetal tracheal occlusion. METHODS: Outcomes in a prospective observational cohort who underwent fetoscopic tracheal occlusion for severe fetal left diaphragmatic hernia without associated anomalies were compared with our historical nontreated cohort of matched fetuses of similar severity. Fetuses were classified using the same ultrasonography and magnetic resonance imaging methodology-prospectively in the fetoscopic tracheal occlusion group and retrospectively in the historical nontreated cohort...

BACKGROUND: Placenta previa, one of the most severe obstetric complications, carries an increased risk of intraoperative massive hemorrhage. Several risk factors for intraoperative hemorrhage have been identified to date. However, the correlation between birth weight and intraoperative hemorrhage has not been investigated. Here we estimate the correlation between birth weight and the occurrence of intraoperative massive hemorrhage in placenta previa. MATERIALS AND METHODS: We included all 256 singleton pregnancies delivered via cesarean section at our hospital because of placenta previa between 2003 and 2015...

We report on an abdominal pregnancy in human immunodeficiency virus-positive mother, currently on antiretroviral therapy, which was discovered incidentally while training the obstetric ultrasound capacity building program. Although abdominal pregnancy is a rare form of ectopic pregnancy, it may be more common in women with HIV infection because they tend to have a higher rate of sexually transmitted diseases than the general population. The positive diagnosis of abdominal pregnancy is difficult to establish and is usually missed during prenatal assessment particularly in settings that lack routine ultrasound examination as is the case in most developing countries...

Post-menopausal metrorrhagias represent a frequent reason for consultation in gynecology. Our study aims to evaluate the contribution of pelvic ultrasonography in the exploration of endocavitary lesions in people experiencing this symptom and to compare the results found with those of hysteroscopy and histology. This was an analytic retrospective study of 33 cases referred for evaluation of postmenopausal metrorrhagias at the department of gynecology and obstetrics «A» in the Center of Maternity and Neonatology of Tunis in 2012...

OBJECTIVE: To screen and detect cortex gyration in fetuses with congenital heart disease (CHD) using Ultrasonography (US) during routine obstetric scans. METHODS: The depth of the Sylvian fissure (SF), parieto-occipital fissure (POF), and calcarine (CF) fissure were prospectively serially measured and compared in 45 fetuses with CHD and 45 normal fetuses. Cardiac hemodynamic parameters, including aortic valve diameter (AV), pulmonary valve diameter (PV), velocity time integral of the aortic valve (VTIav), and velocity time integral of the pulmonary valve (VTIpv), were recorded...

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...

We performed an evidence-based review of the obstetrical management of gastroschisis. Gastroschisis is an abdominal wall defect, which has increased in frequency in recent decades. There is variation of prevalence by ethnicity and several known maternal risk factors. Herniated intestinal loops lacking a covering membrane can be identified with prenatal ultrasonography, and maternal serum α-fetoprotein level is commonly elevated. Because of the increased risk for growth restriction, amniotic fluid abnormalities, and fetal demise, antenatal testing is generally recommended...

Postpartum haemorrhage (PPH) is a potential cause of maternal mortality, and obstetricians must be prepared to rapidly diagnose and treat this condition. Optimal treatment is dependent upon the underlying cause of haemorrhage. Ultrasonography is the most helpful tool for prompt diagnosis of PPH aetiology and obstetricians must have a strong understanding of postpartum ultrasonography. In our previous report, we demonstrated the utility of ultrasonography using the focused assessment with sonography for obstetrics (FASO) technique (a modified version of FAST) as the primary postpartum obstetric survey...
