Abstract：Objective To investigate the clinical features and outcomes of non-hemorrhagic moyamoya disease with aneurysm.Methods Clinical data of 12 patients of non-hemorrhagic moyamoya disease with intracranial aneurysm were analyzed retrospectively.There were 12 intracranial aneurysms,including 11 aneurysms at major arteries and 1 aneurysm at peripheral artery.The sizes of all aneurysms were less than 5 mm.All the patients received encephalo-duro-arterio-synangiosis (EDAS) and follow-up observation was performed on all the aneurysms.Results Eight patients were followed up for 6 to 72 months by DSA examination and 7 patients with major artery aneurysm remained stable and 1 peripheral artery aneurysm disappeared.All patients received clinical followed-up for 4 to 90 months,no stroke occurred.The modified Rankin Scale (mRS) score was 1 points in 5 patients and zero in 7.Conclusions Most of aneurysms in patients of non-hemorrhagic moyamoya disease with aneurysms are major artery type,and all aneurysms are small,do not need treatment at first.Most aneurysms remain stable after EDAS,and some peripheral artery aneurysms may disappear.
