Preparing for your Procedure

Upon arrival, you will be greeted by the receptionist. A staff member will then escort you to the preparation area where you will change into a patient gown. After the nurse reviews your medical history with you and the physician examines your access, the procedure will be explained, and you will have an opportunity to ask questions and you can sign an informed consent form. An IV may be started to provide a route for medication administration during the angiogram.

Vein Mapping

Vein Mapping is a process that is used to visualize your blood vessels in your arms. Dye is injected and the blood flow is observed as x-rays are taken. This information is used to place your vascular access (whether it be a fistula or a graft) in the best location.

Preparation for the test does not require fasting. You can take your medication the morning of your appointment and eat.

Catheter Removal

A hemodialysis catheter removal is performed when a person’s permanent dialysis access is being used and the catheter is no longer needed, when a person no longer needs dialysis or when the catheter has become infected and must be removed.

There is no fasting or medication restriction related to the preparation for the test.

Catheter Procedures

Hemodialysis catheter insertion is performed if you do not have a permanent vascular access or if your current access is unusable for your dialysis treatments. The physician will insert the catheter into a vein in the neck/chest area using an x-ray camera as he verifies the correct placement.

Hemodialysis catheter exchange is performed when your dialysis catheter no longer functions well enough for you to have an adequate dialysis treatment. The physician will remove the old catheter and insert a new one using an x-ray camera. Dye may be injected through the catheter to observe for any narrowing of the blood vessels or scar tissue formation.

Preparation for the test includes not eating or drinking anything after midnight before the test. You are only permitted to take your blood pressure medicine the morning of your appointment with a sip of water. If you are on Coumadin, the nurse will contact you about stopping the medication before your test.

Declot of Vascular Access

A declotting procedure is performed when the blood flow through your fistula or graft has stopped working. Dye is injected with a small needle into your access and the blood flow is observed as x-rays are taken. If there are blockages or narrowings seen during the exam, the physician may remove the clot and restore the blood flow by using a balloon (angioplasty), injecting medicine, or using a special device to remove the clot (Thrombectomy) and improve flow.

Preparation for the test includes not eating or drinking anything after midnight the night before the test. You are only permitted to take your blood pressure medicine the morning of your appointment with a sip of water. If you are on Coumadin, the nurse will contact you about stopping the medication before your test.

Angiogram

An angiogram is performed when you are having a problem with the function of your dialysis access. It is a diagnostic tool in which dye is injected with a small needle into your access and the blood flow is observed as x-rays are taken. If there are blockages or narrowings seen during the exam, the physician may perform other procedures to improve flow.

Some of the reasons the test is scheduled could include:

  • Excessive bleeding from your needle site after dialysis
  • Difficult needle insertions
  • Swelling of your access arm, neck or face
  • High outflow (venous pressures that are monitored during dialysis
  • Low blood flow rates
  • Decreased dialysis clearance levels

Preparation for the test includes not eating or drinking anything after midnight the night before the test. You are only permitted to take your blood pressure medicine the morning of your appointment with a sip of water. If you are on Coumadin, the nurse will contact you about stopping the medication before your test.

After your procedure

After your procedure, the physician will review the results with you. You will be given a snack and discharge instructions. Your dialysis center will receive a verbal as well as written report of the findings.
