BACKGROUND AND PURPOSE: Choroidal collateral anastomosis is associated with
hemorrhage recurrence in patients with Moyamoya disease. However, the relationship …

OBJECTIVE Following hemorrhagic stroke in moyamoya disease, de novo intracranial
hemorrhage can occur in the previously unaffected nonhemorrhagic hemisphere. In the …

OBJECTIVE Choroidal collateral vessels typical of moyamoya disease have received
attention as a potential bleeding source. The authors' previous angiographic cross-sectional …

OBJECTIVE In this paper, the authors set out to identify the angiographic features of
moyamoya disease with posterior hemorrhage, which is a strong predictor of rebleeding …

OBJECTIVE Choroidal anastomosis (ChA) has been implicated as the main indicator of an
increased hemorrhagic risk in adult moyamoya disease. In this retrospective study, the …

Objectives Choroidal anastomosis is a risk factor for hemorrhage in moyamoya disease.
One variant of choroidal anastomosis,“transcallosal anastomosis,” originates from the …

Objectives This study aimed to investigate the association between dilation and proliferation
and anastomosis of perforating arteries, and intracranial hemorrhage in moyamoya disease …

BACKGROUND AND PURPOSE: Choroidal anastomosis, a hemorrhage-prone
periventricular collateral manifestation in Moyamoya disease, outflows to the cortex posterior …

OBJECTIVE This study was performed to identify the angiographic features of hemorrhagic-
onset moyamoya disease (MMD) in comparison with those of patients with ischemic-onset …

Objective Risk factors for rebleeding after revascularization surgery are unclear. We aimed
to evaluate long-term outcomes after combined revascularization surgery for adult …
