Key result
CAS warrants caution versus CEA in low-operative-risk patients due to safety concerns.
Why the study?
Doubts have been raised regarding the safety of carotid artery stenting as an alternative to carotid endarterectomy, especially in low-operative-risk patients.
Does flow reversal improve the safety of carotid artery stenting compared to carotid endarterectomy in patients with carotid stenosis?
Does flow reversal improve the safety of carotid artery stenting compared to carotid endarterectomy in patients with carotid stenosis?
The safety of carotid artery stenting compared to endarterectomy remains debated, prompting investigation into whether techniques like flow reversal can mitigate risks.
Reinforces caution with carotid stenting in low-risk patients; leaves open whether flow reversal narrows its safety gap versus endarterectomy.
Since the publication of the Endarterectomy versus Angioplasty in Patients with Symptomatic Severe Carotid Stenosis (EVA-3S) and Stent-supported Percutaneous Angioplasty of the Carotid Artery versus Endarterectomy (SPACE) studies, doubts have been raised regarding the safety of carotid artery stenting (CAS) as an alternative carotid intervention to carotid endarterectomy (CEA). A recent meta-analysis1 recommended the cautious use of CAS, and concluded that CAS for low-operative-risk patients should be subjected to randomised controlled trials.

Johan Formgren (2007) conducted an editorial in Symptomatic severe carotid stenosis. Carotid artery stenting (CAS) vs. Carotid endarterectomy (CEA) was evaluated. Carotid artery stenting requires cautious use and further randomized controlled trials in low-operative-risk patients due to safety concerns compared to carotid endarterectomy.
