A minimally invasive procedure to treat resistant hypertension.
The procedure uses radiofrequency ablation to burn the nerves in the renal arteries, reducing the nerve activity, which decreases blood pressure.
Local anaesthetic is used for the procedure and is carried out under image guidance.
A catheter is inserted into the femoral artery, and 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.
Radiofrequency ablation will last for around 1-2 minutes.
It is used for resistant hypertension.
Risks associated with the procedure: bradycardia, and changes to the wall of the arteries, which can sometimes lead to renal artery stenosis, and pseudoaneurysm.
In patients with hypertension, ultrasound renal denervation, reduced the daytime, ambulatory systolic blood pressure at two months in the absence of antihypertensive medications versus a sham procedure without post procedural major adverse events (Azizi M).
