The ductus venosus and the mechanism of its closure.
Although recognized since Vesalius as one of the distinguishing features of the foetal circulation, the precise function of the ductus venosus is uncertain. Anatomically, it provides a direct connexion between the umbilical vein and the inferior vena cava. Functionally, it represents a bypass through which part of the oxygenated umbilical blood flows directly into the inferior vena cava. Howeve...
متن کاملIntravenous Paracetamol and Patent Ductus Arteriosus Closure
Background: Standard medical treatments for patent ductus arteriosus (PDA) closure are, including indomethacin/ibuprofen and surgical ligation. Nowadays, a new strategy to close PDA is the use of paracetamol. The present study aimed to describe the use of intravenous (IV) paracetamol for PDA closure in neonates who present a contraindication to ibuprofen or ibuprofen failure with no possibility...
متن کاملCardiac defects in chromosomally normal fetuses with abnormal ductus venosus blood flow at 10-14 weeks.
OBJECTIVE To assess a possible relationship between ductus venosus blood flow abnormalities and cardiac defects in chromosomally normal fetuses with increased nuchal translucency thickness at 10-14 weeks of gestation. METHODS Ductus venosus Doppler ultrasound blood flow velocity waveforms were obtained at 10-14 weeks' gestation immediately before fetal karyotyping in 200 consecutive singleton...
متن کاملTime of closure of ductus venosus in term and preterm neonates.
AIM To investigate the relation between gestational age, birth weight, and antenatal corticosteroid administration and the time of ductus venosus closure. METHODS Ninety eight neonates of 30-41 weeks gestational age were studied by daily ultrasonography until ductus venosus closure. RESULTS In neonates of 30-33 weeks gestational age, the ductus venosus closed at 6.0 (2.4)days (mean (SD)); i...
متن کاملEvaluation of normal fetal ductus venosus using B-flow imaging with spatiotemporal image correlation and traditional color Doppler echocardiography.
OBJECTIVE To explore the feasibility of using four-dimensional echocardiography with B-flow and spatiotemporal image correlation (4DBF-STIC) imaging technology to detect fetal ductus venosus (DV), and establish the normal reference range for the ductus venosus diameter at 18-40 weeks gestation. METHODS This was a prospective observational study to detect the DV in 354 normal fetuses at 18-40 ...
