Frequently Asked Questions
How Does It Work?
Using X-ray imaging and contrast material (often called “dye”) your doctor will insert a catheter into your fistula. This will allow your doctor to see how blood is flowing within the graft and check for blockages or blood clots.
What Happens — Before, During, and After?
When you arrive for your procedure a nurse will greet you and let the team know you’ve arrived. You will be brought into an exam room and asked to change into a gown. Your doctor will greet you, explain the procedure and answer any questions you may have.
You will lie on an exam table for the procedure. The technologist or nurse will connect monitors for your heart rate, blood pressure, and pulse, and an intravenous (IV) line will be inserted into a vein in your hand or arm. This will be used to give you sedatives during the procedure.
How Should I Prepare?
When you arrive, make sure the clinical staff member and radiologist know about any allergies you may have, especially allergies to x-ray dye (contrast media). If there’s any chance you might be pregnant, tell your radiologist.
