The patient was a 60-year-old man with encephalopathy without liver cirrhosis. CT angiography revealed a patent ductus venosus between the anterior segmental branch of the portal vein and the middle hepatic vein. Coils were framed in the patent ductus venosus and then used to fill in the frame. After treatment, transarterial portography showed that the shunt flow of the ductus venosus had decre...

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...

Experimental studies regarding coronary embryogenesis suggest that the endocardium is a source of endothelial cells for the myocardial networks. As this was not previously documented in human embryos, we aimed to study whether or not endothelial tip cells could be correlated with endocardial-dependent mechanisms of sprouting angiogenesis. Six human embryos (43-56 days) were obtained and process...

Objective: To discuss the anatomical features of sinus venosus atrial defect on the basis of a comprehensive transoesophageal echocardiography (TOE) examination and its relation to surgical data. Methods: 24 patients (13 men, 11 women, mean (SD) age 37 (17) years, range 17–73 years) with a posterior interatrial communication closely related to the entrance of the superior (SVC) or inferior vena...

BACKGROUND We present a study of the heart malformations found in a collection of mouse fetuses of the iv/iv strain between days 16.5 and 18.5 of gestation. METHODS AND RESULTS One hundred hearts were serially sectioned and studied by segmental analysis with a light microscope. Forty additional hearts were analyzed with a scanning microscope. Forty percent of the hearts were found to be malfo...

OBJECTIVE It is known from animal experiments that blood flow through the ductus venosus changes with fetal strain. Therefore the ratio of umbilical vein to ductus venosus flow rate in human intrauterine growth retardation and multifetal pregnancies was investigated and compared with that in control subjects. STUDY DESIGN Blood flow rates in the umbilical vein and in the ductus venosus, as we...
