研究目的:

1.评价发病 24h 内急性前循环串联病变取栓及球囊扩张术后血流正常情况下(eTICI≥2b_50 级)同侧颅外段行支架植入术是否能够改善患者神经功能预后。 2.探索发病 24h 内急性前循环串联病变取栓及球囊扩张术后血流正常情况下(eTICI≥2b_50 级)同侧颅外段行支架植入术是否增加患者症状性颅内出血的风险。  

Objectives of Study:

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 24 of onset, can improve neurological functional outcomes. 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 24 of onset, can increase the risk of symptomatic intracranial hemorrhage.

随机方法(请说明由何人用什么方法产生随机序列):

所有入组患者将以 1:1 的比例随机分为试验组和对照组。申办单位研究者通过中央随机系统进行随机化操作,使两组的患者在上述因素的分布相对均衡。各研究中心实行竞争入组,随机分组完成后,不允许交换组别。

Randomization Procedure (please state who generates the random number sequence and by what method):

All enrolled patients will be randomized in a 1:1 ratio into an experimental group and a control group. The sponsor investigator will perform the randomization through a central randomization system so that the distribution of patients in the two groups is relatively balanced with respect to the above factors. Competitive enrollment will be implemented at each study center, and no exchange of groups will be allowed after randomization is completed.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

1.仅患者本人/授权人及进行治疗的医生知晓随机化分组结果,研究终点相关的基线及住院期间访视的评价指标应由对患者分组和实际治疗情况未知的第三方人员进行评价。 2.首要终点的访视由经过培训的第三方人员,在对患者随机分组和实际治疗情况未知的前提下进行标准化访视,并形成随访报告。 3.所有研究相关影像资料将回收进行中心化判读。各访视点影像独立判读,判读者对于患者基线情况、所接受治疗(基线手术治疗过程影像除外)及预后情况未知。

Blinding:

1. Only the patients themselves/authorized personnel and treating physicians will know the randomization results. Evaluation indicators related to baseline and hospitalization visits for the study endpoint should be evaluated by third-party personnel who unknown the patient grouping and actual treatment situation. Third-party personnel will be trained by our center and sent to each center uniformly. 2. The primary end-point visit will be conducted by trained third-party personnel who unknown the patient's random grouping and actual treatment situation, and a follow-up report will be formed. 3. All research-related imaging data will be collected and centrally adjusted. The imaging at each visit point will be independently interpreted, and the interpreter will be unaware of the patient's baseline condition, treatment received (except for baseline surgical treatment process imaging), and prognosis.
