Clinical features and endovascular treatment of ruptured peripheral cerebral aneurysms associated with moyamoya disease: an 8-year single-center experience

PPCA should be considered in the differential diagnosis of hemorrhagic MMD. Aneurysm rebleeding appears to be a potential predictor of poor outcome and therefore aggressive intervention should be advocated. Endovascular embolization may be safe and feasible, and conservative observation should be carefully chosen given the high risk of aneurysm re-rupture.
