Summary
Carotid stenting is not as safe as carotid endarterectomy for severe carotid artery stenosis. A meta-analysis of recent trials shows a higher risk of stroke or death with stenting compared to surgery.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Neurology
Background:
- Carotid artery stenosis is a significant risk factor for stroke.
- Carotid endarterectomy has been the gold standard treatment.
- Carotid artery stenting is an emerging alternative with debated safety and efficacy.
Purpose of the Study:
- To review current evidence on carotid stenting versus carotid endarterectomy.
- To perform an updated meta-analysis of randomized trials.
- To evaluate the safety and effectiveness of both procedures.
Main Methods:
- Systematic review of published studies.
- Meta-analysis of randomized controlled trials, including SPACE and EVA-3S.
- Comparison of procedure-related stroke or death rates within 30 days.
Main Results:
- The meta-analysis revealed a lower rate of stroke or death in patients treated with carotid endarterectomy.
- Preliminary data from SPACE and EVA-3S trials are included.
- The long-term risk-benefit profile of carotid stenting requires further investigation.
Conclusions:
- Carotid endarterectomy appears safer than carotid stenting in the short term for symptomatic severe carotid stenosis.
- Ongoing trials (ICSS, CREST) with larger sample sizes will provide more definitive data.
- Future meta-analyses will refine treatment recommendations and subgroup analyses.

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
