Insights
Simultaneous bilateral carotid artery stenting is a feasible and safe procedure for high-risk patients with severe carotid disease. This approach effectively reduces stenosis without major complications.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Neurology
Background:
- Severe bilateral carotid artery disease poses a significant risk of ischemic stroke.
- Traditional surgical options may carry higher risks in certain high-risk patient populations.
Purpose of the Study:
- To evaluate the feasibility and safety of performing simultaneous bilateral carotid artery stenting in a single session.
- To assess the technical success and early complication rates of this combined interventional approach.
Main Methods:
- Retrospective analysis of 6 high-risk patients (aged 53-83) with symptomatic, bilateral carotid stenosis.
- Treatment involved self-expandable stents and a distal protection device during a single-session bilateral stenting procedure.
- Pre- and post-procedure stenosis measurements were recorded.
Main Results:
- All stenting procedures were technically successful, significantly reducing stenosis from an average of 84% to 10%.
- No procedure-related or 30-day postoperative complications were observed.
- One patient experienced transient bradycardia and hypotension, managed medically.
Conclusions:
- Simultaneous bilateral carotid artery stenting is a feasible and safe option for carefully selected high-risk patients.
- This technique can effectively address severe bilateral carotid stenoses in a single session with a low complication rate.
Abstract:
The authors report their experience in treating a group of 6 high-risk patients with severe bilateral carotid disease by carotid artery stenting in a single session. The patients were men aged 53 to 83 years. All had bilateral, synchronous, symptomatic ischemic disease. Five of the 6 patients had severe bilateral carotid stenoses due to atherosclerotic disease: the sixth had a dissecting aneurysm on one side. All were treated with self-expandable stents: a distal protection device was used. All stenting procedures were technically successful. Stenoses averaged 84 +/- 8% before the procedure and 10 +/- 7% after. No procedure-related complications occurred and no 30-day postoperative complications were found. One patient experienced bradhycardia and hypotension for 1 day and was treated medically. After careful preparation and perioperative procedures in a selected group of patients, simultaneous bilateral carotid stenting procedures are feasible when required and appear to be relatively safe.
