What is renal denervation therapy?
Renal denervation (RDN) is a minimally invasive procedure to treat resistant hypertension. The procedure uses radiofrequency ablation to burn the nerves in the renal arteries. This process causes a reduction in the nerve activity, which decreases blood pressure.
Is renal denervation effective?
Increasing studies strongly prove that renal denervation, a minimally invasive surgery, is a promising new non-drug treatment method that can effectively control blood pressure in patients with resistant hypertension, but the evaluation of the long-term blood pressure control effect of renal denervation for resistant …
How is resistant hypertension treated?
Treatment of resistant hypertension is focused on the addition of fourth-line therapy where blood pressure is not controlled by treatment with three drugs, described by NICE as A+C+D: that is, an ACE inhibitor or an angiotensin II receptor blocker (A), a calcium channel antagonist (C), and a thiazide or thiazide-like …
What is RDN for hypertension?
Catheter-based renal sympathetic denervation (RDN) is a novel therapeutic technique for the treatment of resistant hypertension. Clinical trials of RDN have shown a significant and sustained reduction of blood pressure as well as renal and central sympathetic activity.
What is hypertension resistant?
Resistant hypertension is high blood pressure that does not respond well to aggressive medical treatment. Hypertension is considered resistant when all of the following are true: Someone is taking three* different blood pressure medications at their maximally tolerated doses.
What is refractory hypertension?
Refractory hypertension is defined as uncontrolled blood pressure despite use of ≥5 antihypertensive agents of different classes, including a long-acting thiazide-like diuretic and an MR (mineralocorticoid receptor) antagonist, at maximal or maximally tolerated doses.
What is drug resistant hypertension?
Can only one kidney fail?
Since most people have two kidneys, both kidneys must be damaged for complete kidney failure to occur. Fortunately, if only one kidney fails or is diseased it can be removed, and the remaining kidney may continue to have normal kidney (renal) function.
What is renal denervation for resistant hypertension?
Resistant hypertension refers to high blood pressure which has not responded to medication. Renal denervation (RDN) is a minimally invasive procedure to treat resistant hypertension. The procedure uses radiofrequency ablation to burn the nerves in the renal arteries.
What is renrenal denervation (RDN)?
Renal denervation (RDN) is a minimally invasive procedure to treat resistant hypertension. The procedure uses radiofrequency ablation to burn the nerves in the renal arteries. This process causes a reduction in the nerve activity, which decreases blood pressure. How does the procedure work?
What is radiofrequency ablation for renal stenosis?
During the RDN procedure, radiofrequency pulses are applied, burning the nerves in the walls of the renal arteries. The aim of the procedure is to burn the renal nerves without damaging the arteries. Each application of radiofrequency ablation will last for around 1-2 minutes, though this depends on the device used.
