Recently, five randomized controlled trials (ANGEL-ASPECT \\[Endovascular Therapy in Acute Anterior Circulation Large Vessel Occlusive Patients with a Large Infarct Core\\], LASTE \\[LArge Stroke Therapy Evaluation\\], RESCUE-Japan LIMIT \\[The Recovery by Endovascular Salvage for Cerebral Ultra-Acute Embolism-Japan Large Ischemic Core Trial\\], SELECT 2 \\[Randomized Controlled Trial to Optimize Patient's Selection for Endovascular Treatment in Acute Ischemic Stroke\\], and TENSION \\[The Efficacy and Safety of Thrombectomy in Stroke with extended lesion and extended time window\\]) demonstrated the efficacy and safety of thrombectomy for large infarct patients (defined as Alberta Stroke Program Early Computed Tomography Score \\[ASPECTS\\] ≥3 or infarct core \\\u003C100ml). Patients with extra-large infarct core (ASPECTS score of 2 or less) were excluded from these trials. Therefore, the efficacy of endovascular thrombectomy in patients with extra-large ischemic burden has not been well studied. The XL STROKE registry is aiming to investigate the clinical outcomes and safety of mechanical thrombectomy in acute extra-large ischemic stroke.",[84,85],"Acute Ischemic Stroke (AIS)","Acute Ischemic Stroke From Large Vessel Occlusion",[87,88,25],"Acute ischemic stroke","large vessel occlusion","2025-12-24",{"date":91,"type":92},"2025-12-31","ACTUAL",{"date":94,"type":92},"2024-01-20",{"date":96,"type":79},"2026-03-31",{"name":35,"class":6},1]
