Inflammation: Either as a result of an infection that 'burrows' or from another source, e.g. Ibd (inflammatory bowel disease) - not to be confused with IBS (irritable bowel syndrome).
Dr. Barry Rosen

Inflammation, Cancer: Anything that can cause the intestine to rupture can potentially lead to a fistula. The most common causes include diverticulitis, inflammatory bowel disease, and colorectal cancer. When a hole occurs, the body's natural tendency is to want to seal this perforation. Typically, an adjacent organ will "band-aid" the hole shut, but the inflammation will burrow a hole into this second structure.

How long will it take for my new fistula to mature?

Varies: You probably are refering to a "fistula" for hemodialysis. Maturing refers to the vein dilating ( streching to a larger daimeter than normal as the wall tends to thicken. The amount of flow into the vein will determine the time for "maturing". This may take 2 - 6 weeks. There is a delicate balance between the flow into the fistula and the flow into the tissues ( usually the hand ).

Innumerable: There are dozens of different kinds. A fistula is basically an abnormal connection between parts of the body. You can have fistulas between the arteries & veins, small bowel & colon, intestine & bladder, bowel & vagina, lungs & bile ducts, stomach & lungs, esophagus & trachea.... I think you get the idea.

Are av fistulas permanent?

Don't have to be: It takes a surgical procedure to connect the end if a vein to the side of an artery (create an av fistula). Once created, it will take another surgical procedure to shut the fistula down if need be. Most often they are kept in place even if not used as a back-up system for dialysis access.
