BACKGROUND Angiogenesis has been found to be among the most important factors in the pathogenesis of endometriosis. The formation of new blood vessels is critical for the survival of newly implanted endometriotic foci. The use of 3-D power Doppler allows for the demonstration of the dynamic vascular changes that occur during the process of in vitro fertilization (IVF). We aimed to evaluate the ...

Age is an important determinant of Doppler indices of left ventricular diastolic filling in normal subjects. To define reference values and factors of importance to Doppler indices of left ventricular filling in subjects of similar age, 58 men and 76 women aged 50 years underwent Doppler echocardiography. All those taking part in the study were healthy. When gender was analysed in a multivariat...

Aim of the study To evaluate the value of uterine artery Doppler indices and waveform pattern in predicting fetuses at risk for intrauterine growth restriction in hypertensive disorders of pregnancy. Materials and methods This was a prospective cross-sectional study including 80 pregnant subjects with hypertensive disorders of pregnancy and two control groups. Uterine artery Doppler sonograph...

The aim of this study was to document the Doppler indices [pulsatility index (PI) and resistance index (RI)] of the uterine arteries in 30 patients who underwent hysteroscopic rollerball endometrial ablation for dysfunctional uterine bleeding by transvaginal pulsed Doppler sonography, and to reveal whether treatment failures (persistent menometrorrhagia) can be predicted by the blood flow chara...

Introduction Doppler echocardiography provides a means to non-invasively evaluate the anatomy and function of the heart, and is playing an increasingly important role in the evaluation and management of patients or animals with all forms of cardiac disease [13]. It has now become a routine for the diagnosis and evaluation of heart disease in veterinary medicine [4]. This is especially true in l...

conclusions pci was accompanied by some improvement in left atrial deformation indices as assessed by tissue doppler imaging. revascularization can, therefore, improve patient outcome. results regarding changes in left trial functional parameters after pci, those such as the strain of the septal wall and the anterior and inferior walls and the strain rate of the anterior and lateral walls signi...

Background: It is assumed in polycystic ovary syndrome (PCOS) that follicular development, maturation, ovulation and implantation are impaired due to hormonal imbalance and vascular impairment of the ovarian and uterine vasculatures. The mechanism of action of laparoscopic ovarian drilling (LOD) is largely unexplained. To date, only limited studies have been conducted utilizing 3D ultrasonograp...

BACKGROUND: Determining the clinical significance of cardiac murmurs is widely considered in equine practice. Pulmonary murmurs are commonly detected in athletic horses. Echocardiography plays a leading role in assessment of these murmurs. OBJECTIVES: Echocardiographic evaluation of horses with pulmonary regurgitation and determining the importance of pulmonary valve murmurs. METHODS: A total n...

1. Doppler recordings were made from the brachial artery of healthy female subjects during a series of manoeuvres which altered the pressure-flow characteristics of the vessel. 2. Changes were induced in the peripheral circulation of the forearm by the application of heat or ice-packs. A sphygmomanometer cuff was used to create graded occlusion of the vessel above and below the point of measure...

OBJECTIVES The aim of this study is to determine whether Doppler indices predict intra-ventricular hemorrhage and perinatal mortality in fetal growth restricted pregnancies (FGR). MATERIAL AND METHODS In this cohort study, 43 FGR fetuses underwent multi-vessel Doppler ultrasounds weekly or twice weekly after admission. Blood gases of the umbilical cord were analyzed immediately after delivery...
