De Novo Renal Artery Stenosis Developed in Initially Normal Renal Arteries during the Long-Term Follow-Up of Patients with Moyamoya Disease

Moyamoya disease is a cerebrovascular disease of unknown origin causing progressive stenosis of the intracranial arteries in the circle of Willis.1,2 Stenoocclusive lesions and the subsequent hemodynamic compromise result in the formation of dilated, fragile collateral vessels at the base of the brain, which are termed moyamoya vessels. The presentation of patients with these lesions varies from asymptomatic to symptoms of headache, epilepsy, and ischemic and hemorrhagic stroke. Patients with moyamoya disease sometimes have concomitant extracranial arterial stenosis3; of all the extracranial arteries reported, the most common location of extracranial stenosis is the renal artery.
