Researchers have discovered a promising approach for reducing brain injury risk in patients undergoing carotid artery stenting (CAS). CAS is a procedure commonly performed in elderly patients with blockages in the carotid arteries, which supply blood to the brain.

It carries the risk of cerebral hyperperfusion syndrome, a serious complication where sudden blood flow to the brain leads to injury or even death.

The study assessed the effect of the sedative dexmedetomidine (Dex) on patients undergoing CAS. It found that only 11% of patients receiving Dex developed cerebral hyperperfusion, compared to 38% in a placebo group. Only 3% of patients went on to develop cerebral hyperperfusion syndrome, compared to 14% in the placebo group.

These findings highlight Dex's potential as a protective treatment for CAS patients, particularly those at high risk of stroke. Professor Daqing Ma, from Imperial's Department of Surgery and Cancer, commented, "This could be a significant breakthrough for stent surgery in elderly patients."

Thank you very much and God bless you.

If you have an upcoming stent operation, give this study to your anesthesiologist.

Dexmedetomidine (Dex) greatly reduces the percentage of cerebral hyperperfusion cases from the norm of 38% to only 11%.

I would request this.
