Introduction: Catheter-based renal sympathetic denervation is an emerging therapy for resistant hypertension (RHTN) patients, resulting in a significant blood pressure reduction. The presence of accessory renal arteries and anomalous branching patterns are reported in approximately 20-27 % of patients. However, accessory renal arteries, when smaller than 4 mm in diameter, they are out of the inclusion criteria for renal denervation therapy. For this reason patients with evidence of accessory renal arteries have been excluded in previous clinical trials. Recent data suggest that accessory renal arteries may play an important role in non-response therapy when they do not receive renal denervation treatment., Case Report: In this report, we present the outcome of a patient with resistant hypertension and an anomalous right renal artery, having undergone denervation of both principal and accessory renal arteries. The renal ablation by radiofrequency energy of a distant accessory renal artery resulted in a safe procedure with no clinical complications., Conclusion: Consistent with literature the RDN of all, main and accessory renal arteries, was effective in decreasing patient blood pressure while decreasing the need for antihypertensive medication.
