For the past few runs, my arterial buttonhole has been almost closing up. Visually it looks like it’s disappearing plus the blunt has had to push through the fistula with force that I’ve never had before. Last night I had to use a sharp to go through but when I bled the line, it went very, very slowly. I wanted to see if there was resistance and when I connected a syringe, I was unable to push or pull any blood. I did notice that the 1" section immediately above the site was ballooned a bit. I pulled the sharp, held the site, and then tried again with a buttonhole. This time it worked fine and no ballooning.
Any input on what’s going on?
Thank you! I appreciate your help.
