研究目的: |
1. 主要目的: 比较 EVT 与 BMT 治疗 MeVO 卒中患者的 1 年功能预后(mRS 评分)。 2. 次要目的: 评估 1 年综合预后(功能独立、生活质量、认知情绪状态);识别良好预后的预测因 素;探索 EVT 在特定亚组中的疗效。 3. 探索性目的: 分析 EVT 与长期认知功能、社会回归的相关性。 |
||||||||||||||||||||||
|
Objectives of Study: |
1.Primary Objective: To compare the 1-year functional outcomes (mRS score) between EVT and BMT in patients with MeVO stroke. 2.Secondary Objectives: To assess the 1-year comprehensive outcomes (functional independence, quality of life, cognitive and emotional status); identify predictors of favorable prognosis; and explore the efficacy of EVT in specific subgroups. 3.Exploratory Objective: To analyze the correlation of EVT with long-term cognitive function and social reintegration. |

纳入标准: |
1. 在 2022.01.01 至 2025.06.30期间于参研单位住院治疗的患者; 2. 年龄 18 周岁以上; 3. 卒中前改良 Rankin 量表评分 <= 2 分; 4. 根据临床症状或影像检查初步判断为急性脑卒中; 5. 经 CTA 或 MRA 证实为孤立性中等血管闭塞(定义为大脑中动脉 M2、M3 或 M4 段闭塞;大脑前动脉的 A1、A2 或 A3 段闭塞;大脑后动脉的 P1、P2 或 P3 段闭塞); 6. 发病至就诊时间 <= 6 小时。对影像学提示存在可挽救脑组织的患者(因目前随机对照研究均呈现阴性结果,所以缺乏明确的筛选标准。为了探寻可能获益的影像指标,我们选择较为宽松的入组标准:方案 A.基于灌注成像,不匹配比率 >= 1.2;方案 A不适用时(如部分中心缺乏高阶影像设备,或欠缺分析软件等),则采用方案 B.CT标准:在灌注 CT 的低灌注区域 >= 40% 的区域内,平扫 CT 上无低密度;或 MRI 标准:存在扩散-高信号不匹配(在扩散加权成像 (DWI) 病灶区域 >= 40% 的区域内,液体衰减反转恢复 (FLAIR) 成像上无高信号),时间窗延长至 24 小时); 7. 入院时 NIHSS 评分 >= 4 分或症状明显致残(例如失语,偏盲等)。 |

|
Inclusion criteria |
1. Patients hospitalized at the participating centers between January 1, 2022, and June 30, 2025; 2. Aged 18 years or older; 3. Pre-stroke modified Rankin Scale score <= 2; 4. Initial clinical or imaging diagnosis of acute ischemic stroke; 5. Confirmed isolated medium vessel occlusion by CTA or MRA (defined as occlusion of the M2, M3, or M4 segment of the middle cerebral artery; A1, A2, or A3 segment of the anterior cerebral artery; or P1, P2, or P3 segment of the posterior cerebral artery); 6. Time from symptom onset to hospital arrival <= 6 hours. For patients with imaging evidence of salvageable brain tissue (given negative results from current randomized controlled trials, explicit selection criteria are lacking. To explore potential imaging markers of benefit, we adopt relatively broad inclusion criteria: Option A: Based on perfusion imaging, mismatch ratio >= 1.2; if Option A is not applicable (e.g., some centers lack advanced imaging equipment or analytical software), Option B is used: CT criteria: no hypodensity on non-contrast CT within >= 40% of the hypoperfusion region on perfusion CT; or MRI criteria: diffusion-FLAIR mismatch (no hyperintensity on FLAIR within >= 40% of the diffusion-weighted imaging (DWI) lesion area), with the time window extended to 24 hours); 7. Admission NIHSS score >= 4 or clearly disabling symptoms (e.g., aphasia, hemianopia, etc.). |

|
排除标准: |
1. 合并大血管闭塞; 2. 神经功能缺损症状轻微或迅速好转(接受任何治疗前); 3. 影像学提示闭塞可能为其他原因(如动脉夹层、血管炎、烟雾病); 4. 合并其他可能影响预后的颅内病变(如大的未破裂动脉瘤、动静脉畸形、颅内肿瘤); 5. 既往有严重神经系统或精神疾病,且有碍于评估神经功能; 6. 多支血管闭塞病变(例如:双侧前循环,或前后循环均闭塞); 7. 伴有预期寿命<1年的严重全身性疾病(如晚期癌症、终末期肝肾功能衰竭); 8. 预期不能完成随访。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Concurrent large vessel occlusion; 2. Mild or rapidly improving neurological deficit (prior to any treatment); 3. Imaging suggests the occlusion may be due to other causes (e.g., arterial dissection, vasculitis, moyamoya disease); 4. Presence of other intracranial pathologies that may affect prognosis (e.g., large unruptured aneurysm, arteriovenous malformation, intracranial tumor); 5. History of severe neurological or psychiatric disease that may interfere with neurological assessment; 6. Multiple vessel occlusions (e.g., bilateral anterior circulation or combined anterior and posterior circulation occlusions); 7. Severe systemic disease with a life expectancy of <1 year (e.g., advanced cancer, end-stage liver or kidney failure); 8. Inability to complete follow-up as anticipated. |
