Detailed Description
Acute ischemic stroke is a leading cause of disability and mortality. Emergency thrombectomy is the highest recommended treatment for patients with large vessel occlusion. However, there are still some patients with severe disability or mortality within 90 days after surgery. It is necessary to find new interventions combined to endovascular thrombectomy, which promote the efficacy of endovascular thrombectomy. The investigators' previous studies suggested levofloxacin to be a newly identified neuro-protective agent, which could reduce infarct volume and improve neurologic function in animal models.To evaluate the efficacy and safety of levofloxacin combined with endovascular thrombectomy in treating acute ischemic stroke patients due to large vessel occlusion of anterior circulation, the prospective, multicenter and randomized controlled trial was designed.

Outcome Measures
Primary Outcome Measures
- National Institute of Health stroke scale (NIHSS) after 3 days of Levofloxacin/simulant treatment [immediately after 3 days of Levofloxacin/simulant treatment]
National Institute of Health stroke scale (NIHSS) ranged from 0 to 42, a low value represents a better outcome.
- NIHSS at discharge/7 days [discharge/7 days]
National Institute of Health stroke scale (NIHSS) ranged from 0 to 42, a low value represents a better outcome.
Secondary Outcome Measures
- Hemorrhagic transformation and symptomatic intracranial hemorrhage [24h,3days and discharge/7 days]
defined by computed Tomography (CT) brain scan suggested bleeding, accompanied by an increase in National Institute of Health stroke scale (NIHSS) score of ≥4 points.
- Infarct volume after 3 days of Levofloxacin/simulant treatment [immediately after 3 days of Levofloxacin/simulant treatment]
assessed by magnetic resonance imaging brain scan
- Modified rankin scale (mRS) score at 30 days [30 days]
Modified Rankin Scale (mRS), ranged from 0 to 6, a low value represents a better outcome.
- mRS score at 90 days [90 days]
Modified Rankin Scale (mRS), ranged from 0 to 6, a low value represents a better outcome.
