Orbital atherectomy has been developed as a method to modify calcified plaque in the peripheral vasculature, with extensive experience and data supporting its use in infrainguinal peripheral arterial disease. However, calcific atherosclerotic disease occurs in other vascular beds and may benefit from the application of this technology. In this case report, we describe the first reported use of orbital atherectomy in a renal artery. A 55-year-old male with severe drug-refractory hypertension was found to have renal artery stenosis, with severe calcification of the right renal artery. Orbital atherectomy was utilized for initial plaque modification, and he underwent stenting of the renal artery lesion with an excellent angiographic and clinical result at follow-up. In conclusion, orbital atherectomy is a safe and effective means of plaque modification for severely calcified lesions. The safe and effective use of orbital atherectomy in the renal vasculature suggests an opportunity for ongoing evaluation into expanded roles for this technology beyond the coronary and lower-extremity arterial beds.
