Renal denervation is a new technique approved effective for resistant-hypertension treatment.The common renal denervation system consists of a generator and a flexible catheter.During this minimally invasive procedure,the interventionalist uses a steerable catheter with a radio frequency(RF)energy electrode tip.The RF energy is delivered to the renal artery via standard femoral artery access.A series of 2-minute ablation are delivered in each renal artery to distroy the nerves system.The procedure does not involve a permanent device implant.By deactivating the renal nerves,and therefore reducing sympathetic nerve transmission,a significant and reliable reduction in blood pressure could be achieved.In this review,potential complications and future sights of renal denervation are also discussed.
