纳入标准:

1、患者年龄在30-80岁; 2、症状性颅内段动脉粥样硬化性大动脉(颈内动脉颅内段(C4-C7段)、MCA-M1段、椎动脉V4段、基底动脉)狭窄,且经DSA确认狭窄70%-99%; 3、发病1周内DWI阳性的轻型卒中,随机入组前NIHSS评分<=5分或经灌注检查评估存在显著低灌注表现的中高危TIA,中高危TIA定义为ABCD2评分>=4分; 4、如患者小卒中进展加重(NIHSS评分增加>=2分)则以症状加重时计算发病时间,中高危TIA患者则以最后一次症状发作计算发病时间; 5、靶血管直径范围2.0mm至4.5mm,靶病变血管狭窄长度范围<=14mm; 6、术前mRS评分<=2分; 7、CT或MRI检查未见大面积脑梗死(ASPECT评分>=6分或pc-ASPECT评分>=8分); 8、患者或家属了解本次研究的目的和要求,并签署知情同意书.

Inclusion criteria

1. Patients aged 30-80 years; 2. Symptomatic atherosclerotic large artery stenosis in the intracranial segment (intracranial segment of the internal carotid artery (C4-C7 segments), MCA-M1 segment, vertebral artery V4 segment, basilar artery), with 70%-99% stenosis confirmed by DSA; 3. Mild stroke with positive DWI within 1 week of onset, with NIHSS score <=5 before randomization, or high-risk TIA with significant hypoperfusion assessed by perfusion imaging, where high-risk TIA is defined as ABCD2 score >=4; 4. If the patient’s minor stroke worsens (NIHSS score increases by >=2 points), the onset time is calculated based on the time the symptoms worsened; for high-risk TIA patients, the onset time is calculated based on the last symptom episode; 5. Target vessel diameter range: 2.0mm to 4.5mm, target lesion vessel stenosis length: <=14mm; 6. Preoperative mRS score <=2; 7. No large-area cerebral infarction detected on CT or MRI (ASPECT score >=6 or pc-ASPECT score >=8); 8. The patient or their family understands the purpose and requirements of this study and has signed the informed consent form.

1.造影剂过敏; 2.非动脉粥样硬化性疾病相关狭窄:动脉夹层,moya-moya病、动脉炎性疾病等; 3.靶病变侧穿支病变(穿支闭塞引起的梗死定义为虽MCA、BA狭窄但仅表现为单纯的基底节区或脑干/丘脑梗死); 4.存在靶病变侧颅外段>=70%狭窄; 5.既往同侧血管行血管内治疗术; 6.颅内存在动脉瘤、肿瘤、血管畸形; 7.3个月内同侧任何形式的颅内出血及2周内对侧颅内出血; 8.合并房颤、严重心功能、肝肾功能不全;合并肿瘤、严重疾病预计生存时间小于1年者; 9.血红蛋白低于100g/L,血小板计数小于100×10^9/L,国际标准化比率(INR)>1.5(不可逆),凝血功能障碍或有无法纠正的出血因素; 10.难以控制的高血压:收缩压>185mmHg和或舒张压>110mmHg; 11.血糖控制不佳(随机血糖>22.2mmol/L); 12.入组前30天内有大手术(指三级及以上级别的外科手术,如胃肠肿瘤根治术、关节置换术、肾部分切除术、肾上腺肿瘤切除术、膀胱全切术等涉及涉及重要器官或存在较高并发症风险的手术)史或入组后90天内有手术计划; 13.妊娠或哺乳期妇女; 14.研究者判断不能入组的其他情况。

Exclusion criteria:

1. Allergy to contrast agents; 2. Stenosis related to non-atherosclerotic diseases: arterial dissection, moyamoya disease, arteritis, etc.; 3. Target lesion-side perforating branch lesions (defined as infarction caused by perforating branch occlusion, presenting as simple basal ganglia or brainstem/thalamic infarction despite MCA or BA stenosis); 4. Presence of ≥70% stenosis in the extracranial segment of the target lesion side; 5. Prior endovascular treatment on the same side vessel; 6. Presence of intracranial aneurysm, tumor, or vascular malformation; 7. Any form of ipsilateral intracranial hemorrhage within 3 months and contralateral intracranial hemorrhage within 2 weeks; 8. Patients with atrial fibrillation, severe cardiac dysfunction, or liver and kidney insufficiency; those with tumors or severe diseases with an expected survival of less than 1 year; 9. Hemoglobin below 100 g/L, platelet count less than 100×10^9/L, international normalized ratio (INR) >1.5 (irreversible), coagulation disorders, or uncorrectable bleeding factors; 10. Uncontrolled hypertension: systolic blood pressure >185 mmHg and/or diastolic blood pressure >110 mmHg; 11. Poorly controlled blood glucose (random blood glucose >22.2 mmol/L); 12. History of major surgery within 30 days prior to enrollment (referring to level III or higher surgical procedures, such as radical gastrointestinal tumor surgery, joint replacement, partial nephrectomy, adrenal tumor resection, total cystectomy, and other surgeries involving important organs or with a high risk of complications) or a surgical plan within 90 days after enrollment; 13. Pregnant or breastfeeding women; 14. Other situations deemed by the investigator to be unsuitable for enrollment.
