Understanding Brain Blood Flow After Stroke Clot Removal
What is this trial?
This study looks at what happens to blood flow in the brain after a successful stroke treatment procedure that removes blood clots. Researchers want to understand why some patients improve well after treatment while others don't, even though the clot was successfully removed.
About half of stroke patients don't recover as well as expected after their clot is removed, even though the procedure technically worked. This study aims to identify better ways to detect and understand why this happens, so doctors can eventually help more patients recover.
Do you qualify?
You likely qualify if…
- you are 18 years old or older
- you have had an acute ischemic stroke caused by a blood clot in a major artery in your brain (carotid or middle cerebral artery)
- you have successfully undergone endovascular thrombectomy (a procedure to remove the blood clot)
- your clot removal was confirmed successful by medical imaging
- you can provide written consent to participate, or have a family member or authorized doctor provide it on your behalf
You likely don't qualify if…
- you have a pacemaker, metal implants, or certain metallic tattoos that would make MRI scans unsafe
- you are pregnant or suspected to be pregnant
- you have serious uncontrolled lung or heart disease that makes it unsafe for you to participate
- you have signs of increased pressure inside your skull or active brain bleeding
- you have had a new seizure after your stroke
What participation looks like
After being treated for your stroke, you would undergo special imaging scans (likely MRI) to measure blood flow patterns in your brain. The study team would monitor you and gather information about how well you're recovering. The exact number of visits and follow-up time would be explained by your medical team, but the main focus is on taking detailed pictures of your brain's blood circulation to help understand your recovery.
