Key result
Vessix renal denervation is linked to new renal artery stenosis at 12 months.
Why the study?
Renal denervation is a promising therapy for treatment-resistant hypertension but long-term safety data including risk of renal artery stenosis are lacking.
Case Report (n=1)
Renal denervation may be associated with the late development of renal artery stenosis, warranting caution and long-term follow-up.
May warrant extended renal artery surveillance after denervation; single case leaves open incidence and causality.
Renal denervation has been shown to be safe and effective in reducing blood pressure in treatment-resistant hypertensive patients. We describe a 65-year-old lady with essential hypertension who underwent renal denervation using the Vessix™ single shot multielectrode system. Twelve months later renal duplex scanning documented increased velocities in the left renal artery and repeat angiography confirmed the development of a new stenosis. Although renal denervation is a promising therapy, we advise caution as large randomized blinded studies with long-term follow-up are still ongoing.

Bhamra‐Ariza et al. (2014) conducted a case report in Essential hypertension (n=1). Renal denervation using the Vessix single shot multielectrode system was evaluated on Development of a new renal artery stenosis. Renal denervation using the Vessix single shot multielectrode system was associated with the development of a new renal artery stenosis at 12 months in a 65-year-old woman.
