Summary
This prospective audit compared carotid artery stenting (CAS) and carotid endarterectomy (CEA), finding similar stroke rates. While disabling strokes were slightly higher with CAS, both procedures demonstrated satisfactory outcomes for patients with carotid artery stenosis.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Neurology
Background:
- Carotid artery stenosis is a significant risk factor for ischemic stroke.
- Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are primary interventions for managing symptomatic and asymptomatic carotid stenosis.
- Comparative data on the safety and efficacy of CAS versus CEA, particularly from single-center, prospective audits, are crucial for clinical decision-making.
Purpose of the Study:
- To prospectively audit and compare the outcomes of carotid artery stenting (CAS) versus carotid endarterectomy (CEA) performed by a single surgical team.
- To evaluate procedural success rates, peri-procedural complications, and long-term neurological outcomes (stroke, death) for both interventions.
Main Methods:
- A prospective audit of 440 referred patients between January 2005 and December 2008, with 177 undergoing CAS and 263 undergoing CEA.
- Individualized procedure selection based on specific contraindications for CAS (e.g., severe stenosis, thrombus, tortuosity, calcification, aortic arch anatomy).
- Standardized surgical techniques were employed, with routine use of a protection device for CAS and selective shunting for CEA under general anesthesia.
Main Results:
- The operative risk profile was similar between groups, though CAS patients were more frequently hypertensive.
- A higher proportion of asymptomatic patients (49%) underwent CAS compared to CEA (26%), all with >70% stenosis.
- Stroke rates were comparable (2.3% for CAS vs. 1.9% for CEA, p > 0.05), as were combined stroke and death rates (4.5% vs. 3.4%, p > 0.05). Disabling stroke occurred in 1.1% of CAS patients versus 0.4% of CEA patients.
Conclusions:
- Both carotid artery stenting (CAS) and carotid endarterectomy (CEA) yielded satisfactory results in this prospective audit.
- The study demonstrates comparable neurological outcomes between CAS and CEA, supporting their roles in managing carotid artery disease.
- While disabling stroke rates were slightly higher in the CAS group, the overall findings compare favorably with existing literature.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
