Renal artery denervation (RDN) is a minimally invasive procedure that can effectively lower blood pressure in patients with hypertension.
What is Hypertension?
Hypertension, or high blood pressure, is a common medical condition that affects millions of people worldwide. It is commonly defined as a blood pressure reading of 140/90 mmHg or higher.
What Causes Hypertension?
There are several factors that contribute to the development of hypertension. These include:.
- Obesity
- Smoking
- Inactivity
- Stress
- Genetics
How is Hypertension Treated?
Hypertension can be effectively managed through lifestyle modifications, such as weight loss, regular exercise, and a healthy diet. However, some patients require medication to help lower their blood pressure.
What is Renal Artery Denervation?
Renal artery denervation is a minimally invasive procedure that uses radiofrequency energy to disrupt the nerve signals that contribute to hypertension.
During the procedure, a catheter is threaded through a small incision in the groin and guided to the renal arteries.
How Does Renal Artery Denervation Work?
Renal artery denervation works by reducing the activity of the sympathetic nervous system, which regulates blood pressure. The sympathetic nervous system sends signals to the kidneys to produce more renin, a hormone that raises blood pressure.
By disrupting these signals, RDN can lower blood pressure in patients with hypertension.
Who is a Candidate for Renal Artery Denervation?
RDN is typically recommended for patients with severe hypertension who have not responded to medication or lifestyle changes.
What are the Risks of Renal Artery Denervation?
Like any medical procedure, renal artery denervation carries some risks. These may include:.
- Damage to the renal arteries
- Bleeding
- Infection
- Allergic reactions to contrast dye
What is the Success Rate of Renal Artery Denervation?
Studies have shown that renal artery denervation can lower blood pressure by an average of 20 mmHg, with some patients experiencing an even greater reduction in their blood pressure.
Conclusion
Renal artery denervation is a promising new treatment option for patients with severe hypertension.
While the procedure is still relatively new, early studies have shown promising results for patients who have not responded to traditional forms of treatment.
