Many of the uterine infertility factors are associated with chronic endometritis. Its prevalence reaches 92.6%. Quality of endometrial transformation during the "implantation window" is the basis of successful fertility. In our retrospective comparative study of 101 in vitro fertilization (IVF) cycles, the efficacy of transvaginal Doppler ultrasound (TVDUS) in predicting successful implantation was evaluated. Inclusion criteria were as follows: age younger than 41 years and good quality of embryos. Exclusion criteria were as follows: 41 and older age, poor quality of embryos and uterine cavity lesions...

BACKGROUND: Results from uterine artery Doppler investigations suggest that the aetiology of late preeclampsia with fetal growth restriction may be more similar to the aetiology of early preeclampsia than with late preeclampsia without fetal growth restriction. We hypothesised that a small-for-gestational-age (SGA) birth in a late preeclamptic pregnancy may be associated with increased subsequent risk of early preeclampsia. We also studied effects of maternal factors on risks of preeclampsia recurrence...

BACKGROUND: Morbidly adherent placentation now complicates approximately 1 in 500 pregnancies. Our group and others have demonstrated that antenatal diagnosis of invasive placentation and team-based delivery reduce severe morbidity. Ultrasound and magnetic resonance imaging (MRI) are both employed in the antenatal evaluation of pregnancies with suspected placenta increta/percreta. Accurate diagnosis in this context is essential to direct resources appropriately. Ultrasound methods, including colour and power Doppler, are the mainstays of screening at-risk women, whereas MRI is reserved for diagnostic purposes because of its cost and limited accessibility...

First-trimester screening may be a major advantage over a second-trimester approach since it opens prospects for early and more efficient interventions. The aim of the current study was to evaluate whether the measurement of maternal serum inhibin A, activin A and placental growth factor (PlGF) at three to four months gestation with the second-trimester uterine artery pulsatility index (PI) are useful in predicting preeclampsia in a group of nulliparous women. All the patients also underwent uterine artery Doppler examination to measure the PI at 22-24 weeks gestation...

INTRODUCTION: The purpose of our study was to evaluate the maternal haemodynamic profile in women diagnosed with threatened preterm delivery (TPD) in order to understand the possible pathophysiologic mechanism leading to an increased lifetime risk for future cardiovascular disease. METHODS: Sixty-eight patients diagnosed with TPD were enrolled and assessed using a non-invasive method (USCOM®) to determine the haemodynamic parameters. Cervix length assessment, vaginal and rectal swabs, blood inflammatory indexes, foetal vessel Doppler velocimetry, gestational age at the delivery and neonatal outcomes were considered...

INTRODUCTION: The ability to judge intravascular volume is fundamental in the management of patients with severe preeclampsia. Insufficient intravascular volume can result in decreased oxygen delivery to tissues and exacerbates organ dysfunction. On the other hand, fluid excesses can lead to fluid extravasation and pulmonary edema. Outside of pregnancy, transthoracic echocardiography and lung ultrasonography have become important diagnostic and monitoring tools in critically ill patients...

INTRODUCTION: MCA and uterine artery Doppler PI are commonly used in the evaluation of IUGR. Targets: This retrospective pilot study aims to investigate whether MCA/UtA ratio may identify adverse outcome in late onset IUGRs. A cohort of 69 pregnancies affected with late IUGR which underwent labor induction according to local protocols was retrospectively revised on the relationship between MCA/UtA ratio at first observation and the following adverse outcomes: cesarean section for nonreassuring fetal status, birthweight (expressed as percentile and continuous values, umbilical artery pH, NICU admission and Apgar score < 7 after 1 and 5 min...

OBJECTIVE: To examine whether the maternal renal interlobar vein impedance index (RIVI) as assessed by first trimester ultrasonography is able to predict the later development of hypertensive disorders of pregnancy. METHODS: Venous Doppler parameters of both maternal kidneys were studied in 214 pregnant women at 11 + 0 to 13 + 6 weeks' gestation. Subjects were classified according to the outcomes related to hypertensive disorders. Detection rates and areas under receiver operating characteristic (ROC) curves were determined for the maternal RIVI impedance as a first trimester predictor for preeclampsia (PE) and gestational hypertension (GH)...

INTRODUCTION: Studying the venous compartment may add valuable information on background mechanisms and (patho)physiology of the cardiovascular system in normal pregnancies and pregnancies complicated by preeclampsia. Every component of the venous pulse wave is reflecting a specific stage of the cardiac cycle in the right atrium, and can be recognized in the neck veins, the hepatic and the renal veins. Previous studies have demonstrated the repeatability and reproducibility of venous Doppler sonography and venous pulse transit time in renal interlobar and hepatic veins...
