Congenital lobar emphysema (CLE) is a rare developmental disorder characterized by over distension of pulmonary lobes or segments. Often CLE presents a diagnostic and therapeutic dilemma. Here, we report a case of incidentally found CLE at fetal autopsy of terminated pregnancy due to ventriculomegaly and occipital localized encephalocele detected on sonography in the second trimester. A 41year-...
Intrauterine growth restriction (IUGR) can be described as condition in which fetus fails to reach his potential growth. It is common diagnosis in obstetrics, and carries an increased risk of perinatal mortality and morbidity. Moreover, IUGR has lifelong implications on health, especially on neurological outcome. There is a need for additional neurological assessment during monitoring of fetal ...
BACKGROUND AND PURPOSE Accurate measurement of the lateral ventricles is of paramount importance in prenatal diagnosis. Possible conflicting classifications caused by their measurement in different sectional planes by sonography and MR imaging are frequently raised. The objective of our study was to evaluate the agreement between ultrasonography and MR imaging in the measurement of the lateral ...
BACKGROUND To determine the impact of Cervical Cerclage (CC) for prolongation of pregnancy, maternal and foetal outcome. METHODS This Descriptive cross-sectional study was conducted over a period of 2 years patients with history of two or more recurrent midtrimester abortions/preterm deliveries were included. Those with abnormal foetus, vaginal bleeding and choreoamneonitis were excluded. All...
background: hydatidiform mole is an important obstetric problem which can result in harmful and serious outcomes. in this study, an attempt was made to determine the proportion of hydatidiform mole in prenatal clinics of iran university of medical sciences (iums) to find the precise frequency of this disease. methods: between january 2012 and january 2013, all women who immediately after positi...
background: several studies have assessed the correlation of fetal choroid plexus cyst (cpc) and the risk of congenital anomalies, but few ones have discussed isolated cpc (with no other abnormal sonographic finding). objective: the aim of this study was to determine the outcome of isolated fetal choroid plexus cyst and to specify its clinical significance. materials and methods: this cross sec...
the outcome and proper management of fetal hydronephrosis have not been completely defined. the purpose of this study was to determine incidence and outcome of infants with a history of prenatal hydronephrosis diagnosed by ultrasound. in a three-year period from 2000 to 2003 we identified 211 cases (271 renal units) of fetal hydronephrosis in which renal pelvic anteroposterior diameter was more...
Teratomas are tumors containing tissues derived from all three germinal cell layers. Most teratomas arise in the sacrococcygeal region, with a reported incidence of 1/40,000 births. During labor, severe dystocia may occur in infants with large tumors if delivered vaginally, with an extremely high fetal morbidity and mortality rate. Reported is a case of a large congenital sacrococcygeal teratom...
One of the essential purpose of prenatal care is the measurement of fetal growth and also estimation of fetal age. Sonography is a valid device with measurement of femoral length , Scapula length , Biparietal diameter and abdominal circumference. To compare the value of these parameters in assessing fetal age a cross sectional study on 220 singleton pregnan...
Abstract Background: Epidemiologic studies have shown the relationship of maternal hemoglobin level and abnormal findings in uterine Doppler sonography with pregnancy- related complications. In this study, we evaluated the relationship of uterine artery Doppler velocimetry findings and hemoglobin level with the outcomes of pregnancy in women with preeclampsi...
