Private Renal Denervation Procedure (TREND)


This is a new technique for the treatment of high blood pressure/hypertension,  based around the ablation (removal) of nerves that line the renal (kidney) arteries.

It works by reducing the nerve signals to and from the kidney, by applying microwave energy inside the kidney artery. It is called Transcatheter Renal Denervation Therapy (TREND).

Radiofrequency energy can be applied to “Zap” the nerves controlling blood pressure.

Do I need Renal Denervation?

High blood pressure is usually treated with medication which reduces the heart rate, or dilate blood vessels; these risk having side effects in some people.  Renal Denervation has been shown to reduce blood pressure when tablets alone are not working. We will be able to assist you in deciding if this exciting new therapy is suitable for you.

What is involved and what are the risks?

It is done using a technique similar to an angiogram or angioplasty. The procedure is done under local anaesthesia, and can be a little uncomfortable, so you may need sedation. A pipe is taken from the leg artery up to the kidney. A special tube that can deliver the energy to the right spot is used to apply some “burns” to the nerves that run close by. Trials suggest that substantial blood pressure reductions are achievable in 90% of patients. The risks of the procedure are similar to other percutaneous treatments, commonly bleeding or bruising at the entry site. In addition, there can be pain whilst the energy is applied.
