title: Late renal artery stenosis after percutaneous renal denervation.
abstract: : Renal denervation has been adopted as an additional treatment option to pharmacological antihypertensive therapy in patients with resistant hypertension. However, concerns have been raised with regard to the possible occurrence of renal artery stenosis.Our patient developed renal artery stenosis late after renal denervation, as magnetic resonance angiography 6 months after the procedure had showed no stenosis.Invasive reangiography, which revealed the stenosis, was performed due to recurrent resistant hypertension 28 months after renal denervation. Review of the saved loops of the denervation procedure showed that the stenosis was located near the most proximal ablation point.
