Lymphatic malformation (LM) is a localized and rare benign anomaly of the lymphatic system. Surgery is the primary form of treatment, but total resection is difficult and generally not possible. The least invasive and most effective form of treatment is injection sclerotherapy with sclerosing agents. Here, we report a case of LM in a baby, detected at prenatal ultrasound. The aim of this report...
We present a case of a female infant that was diagnosed on prenatal ultrasound with an oral mass, and subsequently underwent a planned EXIT procedure to secure the airway. Ultimately the epignathus teratoma was excised at 3 days of age. The number of cases in which neonates have survived epignathus teratomas has increased in the past decade due to improved prenatal imaging and the development o...
Parapagus dicephalus conjoined twins are rare but severe complication of multigestational pregnancies. Many conjoined twin pregnancies are diagnosed before reaching viability. We present a case report of conjoined twins reached term. A 35-year-old pregnant woman, who had no prenatal follow up, delivered conjoined twins at Van Maternity Hospital. The total weight of the fetuses was 4750 g. and t...
Accurate prenatal estimation of birth weight is useful in the management of labour and delivery. This study compared the accuracy of ultrasound, clinical and maternal estimates of fetal weight in 246 parous women with singleton, term pregnancies admitted for scheduled caesarean section. The sensitivity and specificity of predicting birth weight by ultrasound measures were 12.6% and 92.1%, by cl...
Background and aims In recent years, evidence has shown that prenatal trafficrelated air pollution exposure influences fetal growth. Changes in mitochondrial DNA (mtDNA) content may represent a biologically relevant endpoint on the mechanisms underlying the association between air pollution and fetal growth restrictions. In this study, we aimed to assess the role of placental mtDNA content on t...
This case involves the rare congenital disorder Sirenomelia, a diagnosis initially suspected during prenatal ultrasound and later confirmed by prenatal MRI. Sirenomelia, or mermaid syndrome, is mainly characterized by variable fusion of the lower limbs and by genitourinary anomalies. The vast majority of cases of this disease result in death secondary to associated renal agenesis or hypoplasia....
Conjoined twins are a rare phenomenon, occurring in 1% of monochorionic twin gestation, with an incidence of 1 : 50 000 to 1 : 100 000. Many conjoined twins have abnormalities incompatible with life, so early prenatal diagnosis is very important for optimal management of both pregnancy and delivery. We report a case of dicephalus parapagus conjoined twins, sharing a single heart, diagnosed at 1...
A significant proportion of fetal anomalies are surgically correctable. Their accurate and reliable prenatal diagnosis is of great importance, and will have significant influence on both postnatal and postsurgical outcome. The influence of prenatal diagnosis of simple structural defects will interfere with organ development. In the light of recent achievements, traditional teratology has to be ...
OBJECTIVE The standard obstetric ultrasound examination includes documentation of arms and legs. The purpose of this study is to review the efficacy of ultrasound for the detection of limb anomalies, the type and incidence of associated malformations and pregnancy outcomes. METHOD All cases of polydactyly (POD), abnormal hand position (AHP), limb reduction defects (LRD) and arthrogryposis (AR...
Purpose: Congenital anomalies of the kidneys and urinary tract (CAKUT) are the most common anomalies identified in newborns. This study aims to demonstrate the prevalence of CAKUT including hydronephrosis diagnosed by antenatal and postnatal ultrasound over a five-year period. Methods: The records of births between May 1, 2009 and April 30, 2014 at our hospital were collected. The number of inf...
