Renal Denervation is a minimally invasive procedure done to help hypertension (high blood pressure) in cases where it is unreactive to other treatments.
Renal denervation is based on the principle that our autonomic nervous system plays an important role in blood pressure regulation. These autonomic nerves fibers are found in abundance around the renal (kidney) arteries. The procedure uses radiofrequency ablation to burn the nerves in the renal arteries, hence reducing the nerve activity, which in turn decreases blood pressure.
- What is the success rate of such procedure?
- If the right patient is chosen and the procedure carried out satisfactorily, over two thirds of the patients will notice an improvement in their blood pressure readings.
- Can I stop all my medication after RDN?
- I will consider RDN as one of the treatment arms on top of the medical therapy to combat resistant hypertension. It is unusual and ill advised to stop all blood pressure pills. Some patients may find that they can come off one or two drugs after RDN. It is best to work with your specialist in reassessing the medication requirement.
- How long will it last?
- The denervation process is permanent but blood pressure is a complex condition that progress with age. If we are not careful with our salt intake and not exercise regularly, it may get out of control a few years down the line.
