Carotid artery stenting
An endovascular procedure using balloon angioplasty and stent deployment to treat carotid artery stenosis, typically with embolic protection devices.
Full Definition
Carotid artery stenting (CAS) involves percutaneous treatment of carotid stenosis through balloon dilation and stent deployment, usually via transfemoral access. The procedure typically employs embolic protection devices such as distal filters or proximal occlusion balloons to prevent cerebral embolization during intervention. CAS is particularly considered for patients at high surgical risk for carotid endarterectomy due to anatomical factors, previous neck surgery, radiation therapy, or significant medical comorbidities. Post-procedural dual antiplatelet therapy is essential for preventing stent thrombosis.
Usage
Usage note: Abbreviate as CAS after first use. Always document embolic protection device type and antiplatelet regimen.
In Context
- "Carotid artery stenting was performed using distal embolic protection with successful deployment of a self-expanding stent." — Interventional procedure note
- "CAS was chosen over endarterectomy due to the patient's previous neck radiation and hostile surgical anatomy." — Treatment selection rationale
