On Friday the surgeon did a fistulagram and ballooned a couple of spots on my graft in my lower arm. But, by the time I got home it wasn't working at all. And again this was Friday (Do not have a procedure done on a Friday). So, now I have to wait until Tuesday for a declot. What is the longest anyone has waited to get a declot and it was successful?
I had a similar experience. My graft was ballooned and the next day it clotted. In my case there was no use trying to declot the graft because the stenosis that caused the problem was no longer treatable. Another round of ballooning would have only briefly opened the graft before it shut down again. Of course your case might be different. Many things can cause a graft to clot. Grafts are easier to declot than fistulas and can be declotted after a longer period of time. I wish you well.
