Current status of renal denervation in resistant hypertension

Resistant hypertension is a frequent form of arterial hypertension that, with the exception of malignant hypertension, constitutes the most dangerous stage of arterial hypertension. Recently we have improved the detection, diagnosis, and therapy of resistant hypertensives. The technique of renal denervation with a catheter has improved the control of blood pressure in such patients. The technique is simple, safe, and available data indicates that it is effective. More data and longer follow-up of patients are required to promote wide acceptance of this new technique.
