Brief Summary
The role of endovascular thrombectomy in patients with extra-large ischemic burden is still unclear. The XL STROKE-2 randomized trial is aiming to investigate the efficacy and safety of mechanical thrombectomy in acute extra-large ischemic stroke patients with large vessel occlusion.

Outcome Measures
Primary Outcomes (1)
Modified Rankin Scale score
Modified Rankin scale score (mRS): scores range from 0 to 6, with 0 indicating no disability, 1 no clinically significant disability, 2 slight disability, 3 moderate disability but able to walk unassisted, 4 moderately severe disability, 5 severe disability, and 6 death
90 days after randomization
Secondary Outcomes (4)
Rate of successful reperfusion
Within 5 minutes at the end of angiogram
Rate of excellent outcome
90 days after randomization
Rate of functional independence
90 days after randomization
Rate of independent ambulation
90 days after randomization
Study Arms (2)
Endovascular thrombectomy
EXPERIMENTALPatients in this group will be treated with medical management plus endovascular thrombectomy
Medical management
ACTIVE COMPARATORPatients in this group will be treated with medical management alone
Interventions
Medical management includes IV thrombolysis, antiplatelet, and/or anticoagulation.
Endovascular thrombectomy with stent-retriever, local aspiration, angioplasty, and/or stenting.
Eligibility Criteria
You may qualify if:
- Age 18 years or older, and modified Rankin scale score = 0 or 1 in patients 80 years or older;
- Acute ischemic stroke within 6 hours from last known well to randomization, or with negative MRI-FLAIR (no change on FLAIR sequence and presence of infarct on MRI-DWI) if \> 6 hours or unknown last known well time;
- Occlusion of the internal carotid artery, M1 or M2 segment of the middle cerebral artery confirmed by CTA/MRA/DSA;
- Baseline ASPECTS score of 0-2 or infarct core volume ≥100ml;
- The patient or patient's representative signs a written informed consent form.
You may not qualify if:
- CT or MR evidence of hemorrhage;
- Evidence of mass effect with ventricular effacement, midline shift or herniation on baseline imaging;
- Vessel tortuosity where it is expected that the thrombectomy device will not be able to reach the occlusion site or result in unstable access;
- History of bleeding disorders, severe heart, liver or kidney disease, or sepsis;
- Currently participating in another investigational drug study;
- Any terminal illness with life expectancy less than 6 months.
