The authors report an anatomical study of the ductus venosus in the stillborn fetus based on resin-corrosion casts and angiography. Study in adult material was done by dissection. In the first part of this paper the classical anatomy of the ductus venosus is described and an anomalous case of a hepatic parenchymal bridge between the left and caudate lobes of the liver is reported. In the second part of this paper study of patency and dilation of the ligamentum venosum to a diameter exceeding 10 mm in adult cadavers is presented. A brief study of portal flow demonstrated that an increase in flow of 30% can be obtained by experimental induction of patency. A patent ligamentum venosum was grafted onto the abdominal aorta in the rabbit. The transplanted segment was fully patent and competent immediately after grafting, but showed thrombosis when the animal was sacrified two months after the operation. In the opinion of the authors, it may be possible to use the patent ductus venosus in man once the problems of long term resistance and patency have been solved. The latter problems are currently under investigation in our laboratory.

Purpose: We aimed to determine fetal liver perfusion in PGDM and GDM pregnancies and to assess the relation of ductus venosus (DV) shunt fraction with adverse pregnancy outcomes.
Methods: We conducted a prospective longitudinal observational study including 188 pregnant women: group I-patients with pregestational DM (PGDM, n = 86), group II-patients with gestational DM (GDM, n = 44), group III-control (n = 58). The patients included in the study underwent ultrasound examination at 30-40 weeks of pregnancy.

To assess the prenatal course and early postnatal outcomes of fetuses diagnosed with tricuspid atresia and to identify predictors of survival. This was a retrospective study of 25 fetuses diagnosed with tricuspid atresia in a single tertiary referral center, evaluating prenatal echocardiographic features and postnatal outcomes. A total of 4 of 29 initially diagnosed fetuses were excluded due to changes in diagnosis or loss to follow-up, leaving 25 fetuses for analysis.

Purpose: Anatomical research on fetal liver venous systems is scarce. This study presents variations, morphometric, and histogenesis data through cadaveric study which can aid prenatal radiological analysis.
Materials And Methods: 10% formalin embalmed 16 fetuses (8-second trimester, 8-third trimester) were utilized.

India, owing to its population structure, faces an enormous burden of children born with congenital heart disease (CHD). Systematic challenges such as limited public health infrastructure, a shortage of trained specialists, and high out-of-pocket expenditures hinder uniform access to comprehensive CHD care. Despite these limitations, Indian pediatric cardiologists have delivered innovative and often cost-effective solutions to challenging clinical problems.

Background: The ductus venosus (DV) is a pivotal component of fetal circulation. Absent DV (ADV) is associated with structural defects, portal vein (PV) anomalies, and chromosomal anomalies. This observational study aims to investigate the impact of ADV on fetal circulation and postnatal outcomes.
