A member asked:

Why is arteriovenous fistula in a limb life-threatening and therefore requires amputation?

A doctor has provided 1 answer

Not likely: most arteriovenous fistulas (AVF) in the limb are small and not life-threatening. The may be congenital, or a result of trauma, surgery or procedures, but, do not often result in amputation. They will usually enlarge if untreated, and this may involve surgery or catheter based procedures depending on the location of the AVF.
