You have had an artificial blood vessel connection made to your aorta and an artery in the hollow of your knee.

Arteries are blood vessels that transport blood away from the heart. They supply all the tissue in the body with oxygen-rich blood. The aorta begins at the heart itself. First it runs upwards and then it arches down through the chest to the abdomen. At around the level of the navel, the aorta branches into 2 large blood vessels. These blood vessels first run to the pelvis and then to the legs.

If blood vessels have narrowed or changed in some other way, part of the body may no longer get a good blood supply. The blood vessels can then be bridged using grafted blood vessels, or connected to other blood vessels so that the tissue gets a better blood supply. To connect blood vessels to one another, an artificial vascular graft can also be used.
