Impact of ischemic stroke topography on early clinical outcome of basilar artery occlusion: a retrospective study

ConclusionUnfavorable early outcomes in patients with BAOS may be explained by a higher likelihood of inferior brain stem infarcts and lower rates of reperfusion success.Clinical relevance statementBasilar artery occlusion due to underlying stenosis is associated with a poorer prognosis than that caused by embolism; these results suggest that aggressive endovascular therapy, usually involving the placement of a permanent stent, may be warranted in these patients.Key PointsInferior brain stem and occipital infarcts are prognostically unfavorable in basilar artery occlusion.Basilar artery occlusion due to stenosis occurs more proximally and is associated with worse outcomes.Differentiating etiologies of basilar artery occlusion may influence how aggressively treated the occlusion is.
