Stroke Clinical Trial
— STARTOfficial title:
Stent Implantation Versus Balloon Dilation for Acute Anterior Circulation Tandem Occlusion: A Multicenter, Prospective, Randomized, Open-label, Blinded End-point Trial
1. To evaluate whether stent implantation on the ipsilateral extracranial segment, after intracranial thrombectomy successful recanalization compared with balloon angioplasty (eTICI≥2b_50) for acute anterior circulation tandem lesions within 24h of onset, can improve neurological functional outcomes(mRS≤2). 2. To evaluate whether stent implantation on the ipsilateral extracranial segment, after intracranial thrombectomy successful recanalization compared with balloon angioplasty (eTICI≥2b_50) for acute anterior circulation tandem lesions within 24h of onset, can increase the risk of symptomatic intracranial hemorrhage.

Secondary | The National Institutes of Health Stroke Scale (NIHSS) score | National Institutes of Health Stroke Scale (NIHSS) score. The NIHSS is a 15-item neurologic examination stroke scale used to evaluate the effect of acute cerebral infarction on the levels of consciousness, language, neglect, visual-field loss, extraocular movement, motor strength, ataxia, dysarthria, and sensory loss. A trained observer rates the patent's ability to answer questions and perform activities. Ratings for each item are scored with 3 to 5 grades with 0 as normal, and there is an allowance for untestable items. The single patient assessment requires less than 10 minutes to complete. The evaluation of stroke severity depends upon the ability of the observer to accurately and consistently assess the patient.
