Key result
Percutaneous renal denervation is linked to late renal artery stenosis 28 months post-ablation.
Why the study?
Concerns exist regarding the possible occurrence of renal artery stenosis after renal denervation in patients with resistant hypertension.
Case Report (n=1)
Renal artery stenosis can occur as a late complication (28 months) after percutaneous renal denervation, highlighting the need for long-term vigilance.
Late renal artery stenosis may warrant extended surveillance after denervation; single case leaves open true incidence and risk factors.
: 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.

Lambert et al. (2014) conducted a case report in Resistant hypertension (n=1). Percutaneous renal denervation was evaluated on Renal artery stenosis. A patient with resistant hypertension developed late renal artery stenosis 28 months after percutaneous renal denervation, located near the most proximal ablation point.
