Dialysis Access Interventions are minimally invasive procedures performed to improve blood flow in the fistula and grafts placed in the blood vessels of dialysis patients. Your doctor may recommend a Dialysis Access Intervention to treat:
Narrowing of dialysis fistula or grafts. When there is decreased flow in a graft or fistula, angioplasty or angioplasty with vascular stenting may be performed.
Thrombosis of dialysis fistulas or grafts. When blood does not flow smoothly, it can begin to coagulate, turning from a free-flowing liquid to a semi-solid gel, called a blood clot or thrombus. When blood clots in a fistula or graft prevent dialysis from being performed, catheter-directed thrombolysis with clot-dissolving drugs or surgical thrombectomy may be performed.
