MCA, middle cerebral artery; M1, first segment of the middle cerebral artery; ACA, Anterior cerebral artery; ACoA, Anterior communicating artery; ICA, internal carotid artery; BA, basilar artery; PCoA, Posterior communicating artery; DSA, digital subtraction angiography. Embolization results were classified using the Raymond classification system: class I = complete occlusion; class II = residual neck; class III = residual sac.
