Summary
Carotid endarterectomy effectively prevents stroke in high-grade carotid stenosis patients. This study found a low complication rate of 2.5%, comparable to larger series.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Neurology
Context:
- Carotid endarterectomy is a procedure to remove plaque from carotid arteries.
- High-grade carotid stenosis poses a significant stroke risk.
- Previous studies indicate a stroke prevention benefit when complication rates are below 6%.
Purpose:
- To evaluate the efficacy and safety of carotid endarterectomy in preventing stroke.
- To assess the surgical morbidity and mortality rates associated with the procedure.
Summary:
- 160 carotid endarterectomy procedures were performed between 1986-1996 on 150 patients with symptomatic high-grade carotid stenosis.
- Indications included transient ischemic attack, amaurosis fugax, and/or minor stroke.
- The study reported a 0.6% mortality rate and a 1.9% disabling stroke rate, resulting in a 2.5% overall serious complication rate.
Impact:
- The findings demonstrate that carotid endarterectomy can be performed with low complication rates.
- This supports the continued use of carotid endarterectomy for stroke prevention in carefully selected patients.
- The study's results are comparable to larger national and international series, validating its findings.
