Hepatic venous connection to a persistent inferior caval vein in left isomerism

Duplication of the superior vena cava associated with atrial termination of the left hepatic vein

Duplication of the superior vena cava (SVC), associated with an aberrant left hepatic vein (LHV), was found in one of the 58 dissected specimens. The right SVC virtually showed a typical appearance. The persistent left SVC, which drained into the right atrium via the enlarged coronary sinus, was formed by the persistence of the left anterior cardinal vein. The LHV opened into the right atrium, due to the persistent left hepatocardiac channel. The left common carotid artery arose from the brachiocephalic trunk as a consequence of a regression of the embryonic aortic sac. The revealed venous and arterial variations seem to be the first reported vascular combination of this type.

Angiographic findings of persistent primitive hepatic venous plexus with underdevelopment of the infrahepatic inferior vena cava in pediatric patients

OBJECTIVE

We describe the angiographic diagnosis and significance of persistence of the primitive hepatic venous plexus with underdevelopment of the infrahepatic inferior vena cava.

CONCLUSION

We recommend that inferior venacavography be performed in routine assessment before surgery of patients with azygos or hemiazygos continuation of the inferior vena cava, in whom redirection of systemic venous blood to the pulmonary artery is contemplated.
