Renal denervation (RDN) is a minimally invasive medical procedure used to treat resistant hypertension, a condition where high blood pressure remains uncontrolled despite taking multiple medications. It targets the overactive sympathetic nervous system, which plays a key role in blood pressure regulation.
How RDN works:
The procedure involves the use of a catheter that is inserted into the renal arteries (the arteries supplying the kidneys).
The catheter emits radiofrequency waves, ultrasound, or other energy forms to ablate (destroy) nerves in the walls of the renal arteries.
By disrupting the signals from the nerves in these arteries, RDN reduces the sympathetic nervous activity that contributes to high blood pressure.
Applications and Efficacy:
Initially, RDN was used specifically for drug-resistant hypertension, but newer studies have expanded its potential for treating other conditions like heart failure, arrhythmias, and chronic kidney disease.
Recent clinical trials have shown promising results, with patients experiencing sustained reductions in blood pressure. However, the long-term efficacy and safety are still being researched.
Risks and Benefits:
Benefits include a significant reduction in blood pressure without major side effects in many cases, and it can be especially useful for patients who do not respond well to medications.
Risks are relatively low but may include vascular complications, infection, or damage to the renal arteries.Write your text here...
