carotid artery stenting
An endovascular procedure involving placement of a stent in the carotid artery to treat stenosis.
Full Definition
Carotid artery stenting (CAS) is a minimally invasive endovascular procedure used to treat significant carotid artery stenosis as an alternative to carotid endarterectomy. The procedure involves percutaneous placement of a self-expanding stent across the stenotic lesion, typically preceded by balloon pre-dilatation and often performed with embolic protection devices. CAS is particularly considered for patients at high surgical risk or those with anatomical factors that complicate surgical access. Post-procedural imaging surveillance is essential to monitor stent patency and detect potential complications such as in-stent restenosis.
Usage
Usage note: Commonly abbreviated as CAS; distinguish from carotid endarterectomy (CEA) which is the surgical alternative.
