Prospective Registry of Endovascular Thrombectomy for eXtra-Large Ischemic Stroke
XL STROKE: A Nationwide Prospective Registry of Endovascular Thrombectomy for Extra-large Ischemic Stroke With Large Vessel Occlusion
Source: ClinicalTrials.gov · Last updated 31 Dec 2025
Brief summary (registry, in English)
Since 2015, many randomized trials have shown that endovascular thrombectomy improve functional outcomes in acute ischemic stroke patients with large vessel occlusion. 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 \<100ml). 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.
