The heart and blood vessels comprise the two elements of the cardiovascular system that work together in providing nourishment and oxygen to the organs of the body. The activity of these two elements is also coordinated in the body's response to stress.
graft vs fistula. A graft is usually in a horse-shoe or letter C shape, and is normally firmer to the touch. Fistulas usually run up and down and are more squiggly shaped, with bumps (pseudo anurisms) and softer to the touch. Here are some good pics of fistulas. For some reason, I could not find any pics of grafts on the net.
Veins and arteries can heal after each use, so a fistula can last a long timeâsome-times decades! Fistulas need fewer repairs in the hospital, so you feel better.After surgery, it takes about 4-6 weeks for a fistula to mature so it can be used for HD. The doctor or nurse will decide when it is ready.
