Stroke study: can a quick blood flow pause boost brain recovery?
NCT ID NCT06967025
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a technique called ischemic postconditioning in 60 stroke patients who already had a procedure to remove a clot. After the clot was removed, doctors briefly stopped and restarted blood flow in the affected artery four times. The goal was to see if this extra step could reduce brain damage and improve recovery. The study also looked at blood markers to understand how the technique might work.

Inclusion Criteria: * The patient is ≥ 18 years of age. * The patient must have symptoms consistent with AIS (i.e. face drooping, arm weakness, speech difficulty, etc.) , with symptoms severity of baseline NIHSS ≥ 6 and beginning less than 24 hours prior to presentation at hospital. * Pre-stroke mRS ≤ 2. * Baseline ASPECTS ≥ 6. * Unilateral middle cerebral artery occlusion, and/or internal carotid artery occlusion. * The patient is eligible for EVT. * Successful recanalization achieved through EVT (eTICI 2b-3). * The patient is willing to provide written informed consent to participate in this clinical trial. Exclusion Criteria: * The interventionalist deems the study device unable to reach the target site. * Adverse events related to thrombectomy, such as contrast extravasation, vascular rupture/perforation, dissection, or embolization to a new territory, detected on post-thrombectomy angiography. * Stent placement performed in the M1 segment of the middle cerebral artery or the terminal segment of the internal carotid artery during thrombectomy. * Angioplasty of more than two cycles of balloon inflation/deflation. * The patient is experiencing cardiogenic shock, systolic blood pressure \[SBP\] \<100 mmHg, HR\>100 bpm and arterial oxygen saturation (pulse oximetry) \<92% without additional oxygen. * The patient has known history of Congestive Heart Failure, hepatic failure, end-stage kidney disease or severe renal failure (clearance \< 30ml/min/1.73m²). * The patient is febrile (temperature \> 37.5 °C) or has experienced an infection with fever in the last 5 days. * The patient has a known hypersensitivity or contraindication to aspirin, heparin, Clopidogrel, tirofiban, or sensitivity to contrast media, which cannot be adequately pre-medicated. * The patient has a known history of bleeding diathesis, coagulopathy, cryoglobulinemia, sickle cell anemia, or will refuse blood transfusions. * The patient has a pre-AIS life expectancy of \<1 year due to underlying medical conditions or pre-existing co-morbidities. * The patient is currently enrolled in another investigational drug or device trial. * The patient is apprehensive about or unwilling to undergo the required MRI imaging at follow-up, has a documented or suspected diagnosis of claustrophobia, or has Gadolinium allergy. * The patient is a female who is known to be pregnant. * Other conditions deemed unsuitable for inclusion by the investigator.
