Management of pediatric patients with moyamoya arteriopathy and middle aortic syndrome: a retrospective single-institution case series

Managing comorbid moyamoya arteriopathy and MAS is challenging, as patients have a higher risk of ischemic perioperative complications. These patients may have hypertension secondary to their aortic disease, and treating the aortic disease may correct the hypertension but with possible new relative hypotension and relative cerebral hypoperfusion. Consequently, moyamoya revascularization prior to aortic repair may be a strategy to reduce the risk of stroke.
