Ductus Venosus
Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
The ductus venosus is a fetal blood vessel that connects the portal vein to the inferior vena cava. It exists only during embryonic development and typically closes shortly after birth, becoming a fibrous cord known as the ligamentum venosum.
