Late stroke treatment study for large vessel blockages
Part of Brain & nervous system, Heart & circulation clinical trials.
This study looks at patients who had an ischemic stroke (a type of stroke caused by a blood clot) more than 24 hours ago and have a blockage in a large brain artery. It compares outcomes for those who get a procedure to remove the clot versus those who get only medical treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You had an ischemic stroke (stroke from a clot) more than 24 hours ago.
- A scan (CT or MRI) confirmed your stroke and shows a blockage in a large brain artery.
- You were treated at the study hospital between January 2018 and January 2028.
- You received either a clot-removal procedure or medical treatment for your stroke.
- You did not have any bleeding in your brain when first seen at the hospital.

This trial compares a procedure to remove a large blood clot from the brain (thrombectomy) with standard medical care for people who had a stroke 24 to 72 hours ago but still have some blood flow around the clot. It aims to see if the procedure can help improve recovery even when started later than usual.
This trial studies a way to sort and treat people with a specific type of acute ischemic stroke (caused by a blockage in a large brain artery). It may help doctors choose the best next steps—either a procedure or medication—faster and more appropriately.
This study looks at how well a procedure to remove blood clots from blocked brain arteries works for people who have had a stroke. It aims to see what factors help people recover better, which could help guide treatment decisions.
This trial studies whether a mechanical procedure to remove a blocked artery can help people with an ischemic stroke caused by a large artery blockage, even when treatment starts 24–72 hours after symptoms began. It also checks that only patients with “salvageable” brain tissue on CT scans are treated.
This study looks at how well a special catheter system works to remove blood clots from smaller arteries in the brain after a stroke. It aims to see if this treatment helps people recover better.
This study records outcomes for people having an acute ischemic stroke treated with an endovascular (catheter-based) procedure. It may help doctors understand how clot-removal treatment works in different patients and hospitals.
