2 years and many surgeries on my graft. You can see the pattern though my arm is upside down. One needle goes into each side of the graft. They attach to tubes which is attached to the machine. One needle pulls my blood, it runs through the dialyzer and goes back in through the other. 3 times a week. A graft is only one way to dialyze. #kidney #kidneypatient #kidneydieaseawareness #educate #thestruggle
