Renal sympathetic denervation (RDN) has been adopted in a number of countries as an additional treatment option to supplement antihypertensive therapy in patients with resistant hypertension. Concerns have been raised with regard to the possible occurrence of renal artery stenosis (RAS). In the following, we present a case of RAS as the consequence of RDN. Baseline angiography demonstrated a right main and upper pole accessory renal artery (Fig. 1) and a single left renal arteiy without significant stenoses. Six ablations were performed in each main renal artery, and 2 ablations were performed in the smaller right upper pole accessory renal artery. There were no procedural complications. After 5 months, due to recurrent hypertension, renal angiography was performed demonstrating an 80% ostial and 70% mid-segment right main renal artery stenosis and a mid 50% stenosis in the right upper pole accessory renal artery (Fig. 1). There was no significant stenosis in the left renal artery. The 2 (ostial and mid) right main renal artery stenoses were successfully stented.
