Arteriovenous Fistula Research
The normal arterial system flows from arteries to capillaries to veins.
When the blood flows directly into a vein, it is called an
arteriovenous fistula. If someone is born with this it is termed
“congenital; ” if it occurs later in life it is called “acquired.”
Acquired fistulas are more common and can happen from a sharp
wound that might occur from a knife or bullet, or it can happen when
the doctor punctures an artery in such a way that it becomes blocked
from scar tissue. If this happens, the doctor must create a fistula to
avoid heart failure or dangerous complications.
Small congenital fistulas can be removed by a vascular surgeon
with laser or coagulation treatment. Acquired fistulas should be
treated as soon as diagnosed to avoid complications.
