One of the body's primary methods for controlling blood pressure involves the sympathetic nervous system. This system includes the major organs that are responsible for regulating blood pressure: the brain, the heart, the kidney and the blood vessels themselves. One key player in long term blood pressure regulation is the kidney. Renal nerves communicate information from the kidney to the brain, and vice versa. In people with hypertension, the renal nerves are hyperactive, which raises blood pressure and contributes to heart, kidney and blood vessel damage.
Renal Denervation (RDN) treatment is being studied in a clinical trial to learn whether renal denervation is a safe and effective treatment option to lower blood pressure for certain patients with uncontrolled hypertension. The SPYRAL HTN Global Clinical Trial Program will attempt to disrupt the hyperactive nerves by applying brief radio frequency (RF) energy near the nerves with an experimental medical device.
A single procedure is performed by inserting a tube in the artery leading to the kidney. Using RF, multiple treatments are performed in each artery to disrupt the hyperactive nerves. Following treatment, the device is removed.
Talk with your doctor about potential risks associated with renal denervation.
