OBJECTIVE: The aim of the study is to assess the relationship between uteroplacental Doppler sonography findings and cerebral diffusion measured by diffusion-weighted magnetic resonance imaging (DWI) in fetuses with early- onset intrauterine growth restriction (IUGR). MATERIAL AND METHODS: The study included 54 pregnant women with fetal IUGR and 15 healthy controls (n: 15). Fetuses with IUGR were classified into 4 groups based on Doppler findings: group 1 (n = 12), umbilical artery (UA) pulsatility index (PI) >95pc; group 2 (n = 11), UA PI > 95 pc and middle cerebral artery PI <5pc; group 3 (n = 21), absent end-diastolic (A-EDF) in UA; group 4 (n = 10), reversed EDF in UA...

BACKGROUND: Fetal growth restriction (FGR) is associated with an increased risk of adverse perinatal outcome (APO). However, distinguishing this condition from smallness-for-gestational age remains elusive. A set of criteria has recently been proposed for such purpose, including the severity of smallness, Doppler parameters and growth velocity. OBJECTIVES: To establish whether the use of growth velocity adds to Doppler evaluation in predicting APO among SGA-suspected fetuses...

This study answers the question of whether ultrasound machine settings and the cardiac cycle can influence 3D power Doppler (3D PD) indices in the evaluation of uterine fibroid vascularisation. These parameters were reported to affect the vascular indices and cause undesired variation. 3D PD ultrasound was performed using three different gain settings: a fixed predetermined gain (50 dB), a higher gain (65 dB) and an individualised subjectively most optimal gain. Two consecutive 3D PD sweeps were taken to evaluate the effect of the cardiac cycle...

The objective of this study was to evaluate the changes in uterine blood flow (UBF) based on the resistance index (RI) and the pulsatility index (PI) by Doppler ultrasonography throughout the estrous cycle in lactating Sahiwal cows (n=9). Cows were randomly selected during their spontaneous estrus. UBF was examined on alternate days in all cows during the estrous cycle. The results revealed that the mean RI values were higher (P<0.05) on day -1 (estrus) than on day 0 (ovulation). The mean RI values followed a consistent pattern on days 2, 4, 6, and 8 (metestrus to early diestrus) and were lower (P<0...

BACKGROUND: Trophoblastic invasion of the uterine spiral arteries substantially increases compliance to accommodate increased blood flow to the placenta. Failure of this process impedes uterine artery blood flow, and this may be detected by uterine artery Doppler flow studies. However, the clinical utility of uterine artery Doppler flow studies in the prediction of adverse pregnancy outcomes in a general population remains largely unknown. OBJECTIVE: We sought to determine the utility of early second-trimester uterine artery Doppler studies as a predictor of small-for-gestational-age neonates...

Uterine artery pseudoaneurysm is a rare but potentially life-threatening complication that can occur after various uterine manipulations. A 34-year-old nulliparous patient with a previous history of four consecutive miscarriages with unknown etiologies underwent transmyometrial oocyte retrieval as a result of malpositioning of the right ovary. Six days later, she experienced massive vaginal bleeding after a day of intermittent bleeding and was transferred to our hospital. At triage, continuous bleeding from the cervical canal was observed...

In this study, a mathematical model of the female circulation during pregnancy is presented in order to investigate the hemodynamic response to the cardiovascular changes associated with each trimester of pregnancy. First, a preliminary lumped parameter model of the circulation of a non-pregnant female was developed, including the heart, the systemic circulation with a specific block for the uterine district and the pulmonary circulation. The model was first tested at rest; then heart rate and vascular resistances were individually varied to verify the correct response to parameter alterations characterising pregnancy...
