NCT04526756

Brief Summary

Mechanical thrombectomy(MT) has been recommended in patients with acute large vessel occlusion stroke(LVO) , especially for those with National Institutes of Health Stroke Scale (NIHSS) score ≥6. However, it is still unclear if patients with minor strokes and LVO also benefit from MT.The aim of this study was to evaluate the safety and efficacy of MT for acute LVO and mild symptoms.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • acute ischemic stroke within 24 hours of symptom onset presenting cortical symptoms (such as aphasia, somnolence,slow-minded,etc.) or vertigo with bilateral pathological signs;
  • age≥18 years old;
  • the NIHSS score before evaluation of thrombectomy\<6;
