Arm cuff trick may shield brain during neck surgery

This study looked at whether a simple, non-invasive procedure called remote ischemic conditioning (RIC) can help protect the brain in people with narrowed neck arteries who are having surgery to clear the blockage. RIC involves briefly inflating a blood pressure cuff on the arm to restrict blood flow, which may trigger the body's natural defenses. The trial enrolled 100 adults and used brain scans to check for new small areas of damage after surgery.
