Redo of percutaneous renal denervation in a patient with recurrent resistant hypertension after primary treatment success.

A 79-year-old patient was treated with percutaneous renal denervation (RDN) due to resistant arterial hypertension in the summer of 2010. After primary treatment success with a decrease of blood pressure from 170/100 to 130/80 mm Hg 6 months postablation, the blood pressure rose again at 12 months despite maintenance of the pharmacologic regimen and the decision was made to perform a second RDN procedure. Three months following the second RDN procedure, blood pressure was lowered to 130/77 mm Hg.
