What Happens During The Procedure? Blood Pressure Procedure (RDN)


Once you and your doctor decide that your treatment path forward includes RDN, you will have discussed the benefits and risks of the procedure as well as what to expect.

On the day of or day before your scheduled procedure, your doctor will take your blood pressure and confirm eligibility and address any final questions that you may have regarding the procedure.

The procedure typically takes about an hour to perform1,2.


Here is a step-by-step guide of what generally happens during the Blood Pressure Procedure: 

  • You will receive an intravenous line (IV) to administer fluids and medications, and your blood pressure and heart rhythm will be monitored.
  • Your doctor will insert a small tube into an artery near your hip. This tube will be guided to the arteries that supply blood to your kidneys. The overactive nerves that may be causing high blood pressure are located outside the walls of these arteries.
  • Special dye (contrast) will be injected through the tube into your bloodstream to allow your doctor to see your arteries on an X-ray monitor.
  • If your arteries are confirmed to be suitable for the procedure, your doctor 
will begin treatment by delivering energy to the overactive nerves.
  • After the RDN procedure is performed, the tube is removed.
  • The RDN procedure requires no implant to the kidneys or the arteries near 
the kidney.
