The ductus arteriosus is a temporary fetal blood vessel that connects the aorta and the pulmonary artery before birth.

The pressure between the heart and lungs of an individual affected by PDA causes some of the oxygenated blood that should go out to the body (through the aorta) to return back through the PDA into the pulmonary artery.

As the heart responds to the increased demands for more oxygenated blood by pumping harder, the pulmonary artery has to change in size and shape in order to adapt to the increased amount and force of the blood.

In some cases, the increase in size and shape changes the pressure in the pulmonary artery and lungs.

An arteriovenous fistula is an abnormal channel or passage between an artery and a vein.

An arteriovenous fistula is an abnormal connection of an artery and a vein.

Although both the artery and the vein retain their normal connections, the new opening between the two causes some arterial blood to shunt (be diverted) into the vein because of the blood pressure difference.

It usually occurs when an artery and vein that are side-by-side are damaged, and the healing process results in the two becoming linked.
