The Common Cardinal Vein (also known as Duct of Cuvier or Cuvier's duct) is a significant structure in the embryonic development of the cardiovascular system in vertebrates. It is formed by the union of the anterior and posterior cardinal veins.

Structure

The Common Cardinal Vein is a paired structure, with each vein draining the corresponding half of the embryo's body. It carries deoxygenated blood from the body to the heart. The vein is located on either side of the embryonic heart and eventually forms part of the superior vena cava and inferior vena cava in the adult.

Development

During embryonic development, the Common Cardinal Vein undergoes significant changes. The right Common Cardinal Vein contributes to the formation of the sinus venosus, which later forms the right atrium of the heart. The left Common Cardinal Vein, on the other hand, largely regresses but contributes to the formation of the coronary sinus and the oblique vein of the left atrium.

Clinical Significance

Understanding the development and structure of the Common Cardinal Vein is crucial in diagnosing and treating certain congenital heart defects, such as persistent left superior vena cava and scimitar syndrome.
