Although renal angioplasty proved to be a safe and effec- tive treatment in atherosclerotic renovascular disease, there is limited data on nonatherosclerotic renal involve- ment and treatment strategies. Takayasu's arteritis is a systemic vasculitis primarily affecting large vessels. Involvement of renal arteries may be associated with severe renovascular hypertension. A 20-year-old female patient presented with complaints of headache and exer- cise-induced pain in the left arm. On physical examination, blood pressures were 100/70 mmHg and 220/100 mmHg in the left and right arms, respectively. Brachial and radial pulses were not palpable in the left arm. Ali laboratory find- ings were normal. Angiographic examination revealed nar- rowing of the left subclavian artery, with well-developed collaterals from the supraclavicular and subscapular arter-ies. Selective renal arteriography showed bilateral stenosis of the renal arteries. Renal artery stenting was performed, resulting in no stenosis in the right, and 20% residual stenosis in the left renal arteries. There was no deteriora- tion in renal functions. Blood pressure was 110/70 mmHg in the right arm three months after the procedure.
