Stroke study: brief balloon puffs after clot removal may limit brain damage

This study tested a technique called ischemic postconditioning in 60 stroke patients who had a major artery blockage and underwent a procedure to remove the clot. After successful clot removal, some patients received four short cycles of inflating and deflating a balloon in the artery to briefly stop and restart blood flow. Researchers wanted to see if this extra step could reduce brain injury and improve recovery, and also looked at blood markers to understand how it works.
