Jiang H, et al. - Adult patients with hemorrhagic moyamoya disease (MMD) were investigated for the long-term outcomes after combined revascularization surgery. Researchers also identified risk factors for initial and recurrent hemorrhage. Findings suggest that combined revascularization surgery could provide help for preventing ipsilateral rebleeding in adult patients with hemorrhagic MMD by improvement of anterior choroidal artery (AChA)-posterior communicating artery (PCoA) dilation and extension in the operated hemisphere. Progression of Suzuki stage in the non-hemorrhagic hemispheres was identified as a strong predictor of subsequent contralateral rebleeding.
