FOSSA DUCTUS VENOSI Meaning and
Definition
-
Fossa ductus venosi is a term used in anatomical and medical contexts to describe a specific anatomical structure in the human body. It refers to a shallow groove or depression known as the fossa or sinus of the ductus venosus. This structure is found within the liver and is formed by the remnant of the vascular connection that existed between the umbilical vein and the inferior vena cava during fetal development.
During fetal life, the umbilical vein carries oxygenated blood from the placenta to the developing fetus. The ductus venosus is a branch of the umbilical vein that diverts a portion of this blood directly into the inferior vena cava, bypassing the liver. This allows the oxygenated blood to mix with deoxygenated blood in the right atrium of the heart, from where it is distributed to the developing body.
After birth, the umbilical vein and ductus venosus close and become non-functional structures. The fossa ductus venosi is the remnant left by the closed ductus venosus within the liver. It serves as a landmark in the liver's anatomy and is important in understanding the fetal circulation. The fossa ductus venosi has significance in various medical imaging studies and surgical procedures involving the liver, as it can help guide medical professionals in navigational assessments and interventions.
