Carotid Angioplasty & Stenting
Carotid angioplasty and stenting (CAS) is a fairly new technique for treating carotid artery disease. In essence we place a stent across the blockage with the goal of restoring the normal blood flow channel.
The stent acts as scaffold, holding the plaque in place to prevent parts of it from travelling to the brain. Unlike an endarterectomy we do not remove the plaque.
Much like other angioplasty procedures it is minimally invasive and only requires a puncture site in a groin artery. Most patients will go home the following day after a carotid angioplasty and stenting procedure.
Because it is a relatively new procedure it is still being intensely studied. It is currently available as an option to patients who are “high risk” for surgery. High risk patients have very blocked arteries and have had a stroke or mini-stroke or have other severe medical problems
