My father had a fistula inserted in his right upper arm in April.   He has not started dialysis but has been told the fistula is not working and is considering a "balloon" procedure to clear it.   What are the risks of this and the likelihood of success?
The fistulas have a success rate of 71 % to 100 % and the patency rate is 32 % at 30 days post procedure and these statistics can vary depending on the expertise of interventional radiologist. SO Likelihood success? Expertise of the procedure performer. S Khan
