Use of shockwave intravascular lithotripsy for the treatment of calcified renal artery stenosis in a symptomatic subject

The use of shockwave lithotripsy for the treatment of heavily calcified atherosclerotic plaques before stenting showed great results in terms of feasibility and safety with favorable initial success. Evidence suggests that it is a useful tool to treat calcified lesions in peripheral and coronary arteries. Here, we describe the case of a patient with calcified renal artery stenosis successfully treated with the shockwave lithotripsy system. We present a 76-year-old man with a known significant atherosclerotic renal artery stenosis and refractory hypertension. The patient received an angioplasty of the right renal artery in the first session and he was admitted for a second session to intervene in the left renal artery. The lesion was successfully treated with the lithotripsy system. Final angiography demonstrated an excellent position of the stent and good wall apposition. Our clinical case demonstrates that lithotripsy is safe and effective also for the treatment of the renal artery.
