Carotid Stenting
Carotid Stenting
Carotid artery stenting (CAS) is a minimally invasive, catheter-based procedure used to treat narrowing of the carotid arteries and help reduce the risk of stroke. By restoring proper blood flow, carotid stenting offers an effective alternative to open surgical treatment for selected patients.
When Carotid Stenting Is Needed
Carotid artery narrowing may be:
Asymptomatic, discovered incidentally during imaging
Associated with transient ischemic attacks (TIAs)
Linked to strokes (cerebrovascular accidents)
Early identification and treatment can significantly reduce stroke risk.
Carotid Stenting vs. Surgery
Findings from major clinical studies, including the CREST trial, have shown:
No significant difference in overall outcomes between stenting and surgery
Lower risk of heart attack with carotid stenting
Higher risk of minor stroke with stenting compared to surgery
Higher risk of minor stroke with stenting compared to surgery
