It is known as patent ductus venosus when it remains patent in adulthood. PATIENTS A 43 year old man with a history of panhypopituitarism presented with recurrent bouts of pedal oedema associated with fatigue, hypoalbuminaemia, and elevated prothro...
متن کاملUltrasonographic study of ductus venosus in healthy neonates.
AIM To assess ultrasonographically the flow pattern and the time of postnatal closure of ductus venosus related to the other fetal shunts. METHODS Fifty healthy, term neonates were studied from day 1 up to day 18 using a VingMed CFM 800A ultrasound scanner. RESULTS Ductus arteriosus was closed in 94% of the infants before day 3. Ductus venosus, however, was closed in only 12% at the same ti...
متن کاملAgenesis of Ductus Venosus Presenting with Dilated Inferior Vena Cava with Favorable Outcome

The ductus venosus is a small vein transmitting oxygen-rich blood from the umbilical vein to the fetal heart.. Increasing numbers of case reports are being published about ductus venosus agenesis with cardiac structural abnormalities, other malfor...
متن کاملThe ductus venosus and intrahepatic venous system in Callithrix jacchus jacchus and Macaca fascicularis fetuses.
BACKGROUND The ductus venosus (DV) and the intrahepatic branches of the portal vein are arranged as parallel vessels. Blood shunting through the DV ensures fetal survival during periods of stress. The availability of a suitable animal model with similar structure and function to the human fetus would greatly improve the understanding of DV function. The anatomical and histological structure of ...
متن کاملFetal ductus venosus pulsatility index and diameter during 20-30 weeks gestation.
OBJECTIVE To present normal range of the pulsatility index and the smallest diameter in the ductus venosus in normal fetuses throughout gestation. MATERIAL AND METHOD This was a prospectively cross-sectional study. Three measurements were made for the ductus venosus diameter and the pulsatility index in each fetus during fetal quiescence. Statistical Package for the Social Sciences 14.0 softw...
