pulling clotts from graft

[sullidog]

There's an area on the bottom of my graft that every time we canulate it we pull out big clots. My graft still has a nice thrill but the brui is making a wiezy sound on the bottom where it connects to the artery. My center did an access flow test and it was well above 600, they are going to run it again just to be sure. They don't wanna refer me to the surgeon just yet because it still seems to run good accept for the clots being pulled in that area. Should I request the fistulagram? or since it's running good accept for that one location should I wait until we start to have problems all over the graft? I'd say there's stenosis in that one area hence the weezing sound.
