CAS (Carotid Artery Stenting)

Carotid Artery Stenting (CAS) is a minimally invasive procedure used to open narrowed carotid arteries, which supply blood to the brain. During the procedure, a small balloon is first used to expand the artery, and a tiny mesh tube called a stent is then placed to keep the artery open. This helps restore proper blood flow and reduces the risk of stroke caused by blockages or artery damage. CAS is typically performed under local anesthesia and imaging guidance, offering an alternative to open surgery, especially for patients at higher surgical risk.
