Fetal Doppler velocimetry at high altitude

Doppler velocimetry of normal human fetal venous intrapulmonary branches.

OBJECTIVES To describe the nature of flow velocity waveforms from fetal middle and distal venous pulmonary branches in the second half of normal pregnancy in relation to gestation, and to test repeatability and interrelationships of flow velocity waveform recordings from proximal, middle and distal venous pulmonary branches. DESIGN Cross-sectional study. SUBJECTS/METHODS A total of 111 norm...

[Doppler ultrasound velocimetry for fetal surveillance: critical analysis].

A avaliação da vitalidade fetal é, sem dúvida, de grande utilidade em Obstetrícia, sendo a dopplervelocimetria um dos métodos disponíveis para essa finalidade. Na atualidade, apesar do reconhecimento da utilidade da dopplervelocimetria para avaliação do bem-estar fetal, tem sido necessário que se reflita sobre que casos realmente se beneficiam dessa tecnologia e também sobre algumas particulari...

Doppler velocimetry for predicting fetal death in a twin pregnancy.

Early detection of poor fetal prognosis by serial Doppler velocimetry in high-risk pregnancies.

Fifty-three high-risk pregnancies were followed up serially with Doppler velocimetry of the umbilical artery and uterine vessels from early on to investigate whether abnormalities in Doppler waveforms can predict the outcome of pregnancy accurately before other clinical signs develop. Results of Doppler velocimetry were withheld from the clinicians managing the patients. When the absence of end...

Umbilical Venous Doppler Velocimetry to Supplement Conventional Arterial Doppler to Assess Third Trimester Fetal Growth Restriction

HKJGOM 2009; 9 (1) 28 Introduction Fetuses born with significant growth restriction have an increased risk of adverse perinatal outcomes1. Moreover, increased perinatal morbidity and mortality was often associated with the presence of abnormal Doppler waveforms in the umbilical arteries (UAs), either in the form of absent or reversed end-diastolic flow2,3. In fetuses with abnormal umbilical art...
