Global registry targets dangerous bleeding during stroke clot removal

The PREVENT study is a large, worldwide registry that will track 1,000 stroke patients who undergo a clot-removal procedure called thrombectomy. Researchers want to understand why a blood vessel sometimes gets poked during the procedure, causing dangerous bleeding. By studying medical images and patient outcomes, they hope to create a simple classification system to help doctors quickly decide how to stop the bleeding and whether to continue the procedure. This is an observational study, so it won't test a new drug or device, but it could lead to safer techniques and better emergency care.
