Among these, stroke caused by large vessel occlusion (LVO) are associated with particularly poor outcomes. Multiple randomized controlled trials have demonstrated that endovascular thrombectomy (EVT) significantly improves clinical outcomes in patients with acute LVO and is recommended as the standard of care by current guidelines. Posterior circulation strokes account for approximately 20% of all ischemic strokes and are generally associated with worse prognosis than anterior circulation strokes, especially in patients with basilar artery occlusion, who have a markedly increased risk of death or severe disability. Despite EVT treatment, more than three-quarters of these patients remain dead or functionally dependent at 90 days, indicating substantial room for improvement.\n\nSuccessful recanalization and restoration of effective cerebral perfusion are critical for achieving favorable outcomes. However, although recanalization rates exceed 80% with current thrombectomy techniques, fewer than 40 of patients achieve good functional outcomes at 90 days, suggesting a high incidence of futile recanalization. The underlying mechanisms may include no-reflow, reperfusion injury, and microcirculatory dysfunction, all of which are closely associated with post-recanalization neuroinflammation.\n\nMinocycline is a second-generation tetracycline with pleiotropic neuroprotective properties, including inhibition of microglial activation, reduction of inflammatory mediators, suppression of matrix metalloproteinases, attenuation of oxidative stress, and preservation of blood-brain barrier integrity. Preclinical and clinical studies suggest that minocycline may improve neurological outcomes in patients with AIS.\n\nThis study is a multicenter, prospective, double-blind, randomized controlled trial designed to evaluate the safety and efficacy of adjunctive minocycline in patients with acute posterior circulation arterial occlusion who achieve successful recanalization after EVT. The trial will assess whether early administration of minocycline improves functional outcomes and reduces the incidence of futile recanalization.",[78,79,80,81,82],"Acute Ischemic Stroke","Endovascular Thrombectomy","Minocycline","Posterior Circulation","Arterial Occlusion",[78,79,80,84],"Posterior Circulation Arterial Occlusion","2026-05-19",{"date":87,"type":88},"2026-05-22","ACTUAL",{"date":85,"type":88},{"date":91,"type":71},"2028-12",{"name":33,"class":6},1]
