The controversial role of the Ductus Venosus in hypoxic human fetuses [PDF]
, 2019 The ductus venosus plays a critical role in circulatory adaptation to hypoxia in fetal growth restriction, but the mechanisms still remain controversial.

The Journal of Physiology, EarlyView.Abstract figure legend This review utilized animal models of complicated human pregnancies that result in reduced fetal nutrient or oxygen delivery, or combined nutrient and oxygen delivery, to elucidate their independent and/or synergistic contributions to the development of high‐risk cardiac phenotypes.

Alterations in ductus venosus velocity indices in relation to umbilical venous pulsations and perinatal outcome. [PDF]
, 2015 Abnormal blood velocity in the ductus venosus is more frequently detected than pulsations in the umbilical vein, but both are considered indicators of fetal compromise.

Brain sparing in fetal growth restriction: The double‐edged sword of fetal hypoxaemia
The Journal of Physiology, EarlyView.Abstract figure legend The double‐edged sword of brain sparing. Fetal hypoxaemia triggers a coordinated adaptive response characterised by redistribution of cardiac output toward essential organs, including the brain, and a reduction in overall metabolic activity to preserve oxygen supply.

The 9th International RASopathies Symposium
American Journal of Medical Genetics Part A, Volume 200, Issue 8, Page 1934-1941, August 2026.ABSTRACT The RASopathies are a group of congenital disorders with overlapping clinical manifestations that are caused by pathogenic germline or early somatic variants that result in the hyperactivation of the RAS/mitogen‐activated protein kinase (MAPK) signaling pathway.

Ductus Venosus in the First Trimester: Contribution to Screening of Chromosomal, Cardiac Defects and Monochorionic Twin Complications [PDF]
, 2010 In the first trimester the ductus venosus can be easily identified with color Doppler and a ductus venosus waveform can be obtained by pulsed Doppler. At 11–13 weeks the prevalence of abnormal a-wave in the ductus venosus is inversely related to fetal ...

Catheterization and Cardiovascular Interventions, Volume 108, Issue 1, Page 214-220, July 1, 2026.ABSTRACT Neonates with infracardiac total anomalous pulmonary venous connection (TAPVC) frequently require urgent treatment. If surgical repair is contraindicated due to extreme prematurity, interventional stenting of the ductus venosus (DV) has been introduced successfully to postpone surgery.

Dilatation of the ductus venosus in human fetuses: ultrasonographic evidence and mathematical modeling [PDF]
, 1998 Autonomic regulation of blood flow through the fetal ductus venosus has been suggested, but the existence of a sphincter at the ductal entrance in human fetuses has yet to be established.

Clinical Case Reports, Volume 14, Issue 7, July 2026.ABSTRACT Triplet pregnancies are rare (~0.1% of births) and often complicated by prematurity. When one placental unit is monochorionic, there is a risk of twin‐to‐twin transfusion syndrome (TTTS), a severe vascular imbalance affecting monochorionic gestations.

Journal of Pediatric Surgery Case Reports, 2015 Left-sided diaphragmatic hernia (CDH) as well as ductus venosus agenesis (ADV) are rare complex congenital malformations. We present a case of coincidence of these malformations and an abnormally high lung-head-ratio (LHR).
