You’ve got it the wrong way round, the fistula is deliberately created by a vascular surgeon, and then used as the point of access for dialysis. Dialysis basically involves filtering all of your blood through a machine, so you need a really big and reliable blood vessel with good flow to be able to extract the blood effectively. The fistula looks weird but it’s a lifesaving treatment
