Note:—Angio. indicates angiographic; FU, follow-up; PA, parent artery; R, right; L, left; PAO, parent artery occlusion; HH, homonymous hemianopsia; mRS, modified Rankin scale (0 means no symptoms, 1 minor symptoms, 2 some restriction in lifestyle); Calcif, calcification; MCA, middle cerebral artery; ACA, anterior cerebral artery; PCA, posterior cerebral artery.
