简要总结
To investigate whether using balloon guide catheter with flow arrest during mechanical thrombectomy, compared to non-flow arrest, improves the rate of first pass expanded Thrombolysis in Cerebral Infarction score (eTICI 2c-3) reperfusion for acute ischemic stroke due to internal carotid artery occlusion

入选标准
- •age ≥18 years;
- •Clinical diagnosis of acute ischemic stroke with internal carotid artery occlusion confirmed by imaging (CTA/MRA/DSA), including isolated intracranial internal carotid artery (I-type), internal carotid artery intracranial segment involving middle cerebral artery (L-type), or internal carotid artery intracranial segment involving middle and anterior cerebral arteries (T-type) (including tandem embolic occlusions of the internal carotid artery C1 or common carotid artery);
- •Baseline NIHSS≥6, and meeting local guidelines for mechanical thrombectomy;
- •Time from onset or last known normal to randomization within 24 hours and proceeding to mechanical thrombectomy;
- •Signed informed consent (or by legal representative).
排除标准
- •Pre-stroke mRS score >2
- •Intracranial hemorrhage shown on imaging;
- •Known or suspected internal carotid artery occlusion caused by dissection or atherosclerosis;
- •Vascular tortuosity preventing the use of balloon guide catheter;
- •Prior stent implantation in the target vessel that would impede the use or removal of mechanical thrombectomy devices;
- •Any other circumstances impeding mechanical thrombectomy implementation;
- •Acute occlusion of multiple vascular territories in bilateral anterior circulation or in both the anterior and posterior circulations confirmed by CTA/MRA;
- •Pregnant subjects;
- •Subjects allergic to contrast agents;
- •Subjects refusing to cooperate or unable to tolerate interventional procedures;
- •Subjects whose expected lifetime are less than 90 days;
- •Midline shift or herniation with ventricular mass effect;
- •Subjects deemed unable to participate in follow-up by investigators;
- •Other situations deemed unsuitable for balloon guide catheter use by investigators.
