Background: Accurate estimation of gestational age (GA) is crucial for providing quality health care and need intervention in inadvertent conditions such as fetal growth restriction. Various parameters are used measuring GA, but none them valid 3rd trimester. Recently some studies focused on Fetal kidney length (FKL) measurement correct GA. This study the validation accuracy FKL.Objective: Esti...
BACKGROUND This study was conducted to observe the prevalence of vitamin D deficiency during pregnancy and the effects of maternal 25-hydroxy-vitamin D (25-[OH]D) levels on fetal bone growth. METHODS Five hundred twenty-three Korean pregnant women were randomly recruited and serum 25-(OH)D level was measured. During pregnancy, fetal ultrasonography and serum 25-(OH)D measurements were carried...
Abstract Background: Hydronephrosis is the most common congenital condition that is detected by prenatal ultrasonography. Moreover, the widespread use of prenatal ultrasonography results in an increased recognition of fetal hydronephrosis. Prenatal hydronephrosis is diagnosed at an incidence of 1:100 to 1:500 by ultrasonographic studies. The presence of hydronephrosis is not synonymou...
The most serious congenital abnormalities are those involving the central nervous system (CNS). Ultrasound (US) examination is a safe and noninvasive method for detecting these anomalies during pregnancy. Objective: To find out frequency of fetal detected on ultrasonography. Methods: It was cross sectional study conducted 385 pregnant women using Convenient Sampling Technique. patients were ref...
INTRODUCTION Iodine is essential for normal fetal and neonatal development. We studied the prevalence and impact on fetal thyroid development of iodine deficiency in pregnant women in the northern part of the Paris conurbation. MATERIALS AND METHODS 110 patients underwent several determinations of urinary iodine excretion (UIE) and of serum FT4, FT3, and TSH. Fetal thyroid gland size was asse...
The prolonged retention of fetal bone structure is an uncommon condition after a previous abortion. We describe two cases with fetal bone fragment amongst 3589 hysteroscopies (0.05%), who had no complaint other than secondary infertility. In both patients, hyperechogenic areas were found through transvaginal ultrasound and the bones were removed by hysteroscopy. Despite meticulous evaluation du...
The chief obstetrical problems encountered today in the prenatal evaluation of the high-risk fetus are presented. Advantages and pitfalls or recent techniques utilized in the management of the high-risk pregnancy are discussed. They include: a prenatal scoring system for identifying the high-risk population; examination of the karyotype of cells in amniotic fluid, and quantitation of alpha-feto...
For the last years three-dimensional ultrasonography has become an imaging diagnosis method of great importance in obstetrics. One of its advantages would be the higher sensitivity compared with two-dimensional ultrasound in the diagnosis of some fetal malformations. The potential applications of this new method would be an improved accuracy in the measurement of fetal organs, the possibility o...
Trauma in pregnancy remains one of the major contributors to maternal and fetal morbidity and mortality. Potential complications include maternal injury or death, shock, internal hemorrhage, intrauterine fetal demise, direct fetal injury, abruptio placentae, and uterine rupture. The leading causes of obstetric trauma are motor vehicle accidents, falls, assaults, and gunshots, and ensuing injuri...
