Phase 3 — Testing in thousands of people, comparing the treatment against what doctors currently use. This is the last big step before approval.
This trial is testing argon, an inert gas, to see if breathing it during and after carotid artery surgery can protect your brain from injury. About one in five patients experience small, silent strokes after this surgery that can affect memory and thinking, even though the surgery itself is successful. Researchers want to know if this medication can reduce brain damage and help you recover better.
Even after successful neck artery surgery, many patients develop subtle brain injuries that cause memory problems and cognitive decline. Currently, doctors have no reliable way to prevent these complications, so this trial is testing whether this treatment can reduce brain damage and improve long-term outcomes.

You would be randomly assigned to breathe either the argon gas mixture or a control gas mixture during your carotid artery surgery and in the recovery period afterward. Before surgery, you'll complete cognitive and neurological assessments. The trial will monitor your thinking, memory, and brain health before and after surgery to see if the special gas helps protect your brain during the procedure.
