Carotid endarterectomy. One solution to the stroke problem
Insights
Stroke is often caused by extracranial artery disease and is preventable. Carotid endarterectomy is effective for transient ischemic attacks, with low complication rates in experienced hands.
Area of Science:
- Neurology
- Vascular Surgery
- Public Health
Background:
- Stroke, frequently caused by extracranial cerebral artery disease, leads to significant mortality and morbidity.
- Stroke is a preventable condition, often treatable through management of transient ischemic attacks or asymptomatic carotid bruits.
- Improving patient education and physician awareness can reduce stroke incidence.
Purpose of the Study:
- To evaluate the efficacy and safety of carotid endarterectomy.
- To analyze outcomes of carotid endarterectomy performed by residents under supervision.
- To inform surgical decision-making for stroke prevention.
Main Methods:
- Prospective analysis of 200 carotid endarterectomies performed over 4 years.
- Surgical procedures conducted by senior residents under direct author supervision.
- Literature review to support findings and treatment recommendations.
Main Results:
- Operative mortality was 1.5%.
- Perioperative stroke rate was 1.5%.
- Temporary neurologic deficit and cranial nerve injury rates were both 1%.
Conclusions:
- Carotid endarterectomy demonstrates favorable outcomes with low complication rates.
- An aggressive surgical approach is supported for patients with transient ischemic attacks.
- A more cautious approach is recommended for patients with prior stroke or asymptomatic stenosis.
Abstract:
Stroke is most often the result of extracranial cerebral artery disease; stroke carries a high initial mortality and morbidity and portends an increased risk of subsequent stroke or myocardial infarction. Stroke is also a preventable disease in more than one half of patients, either by approximate treatment of premonitory transient ischemic attacks or by appropriate evaluation of otherwise asymptomatic carotid bruits. Combined patient education and referring physician awareness should result in a declining incidence of stroke in this country. Two hundred carotid endarterectomies were performed over a 4-year period by senior residents under the direct supervision of the authors. Operative mortality was 1.5 per cent; perioperative stroke, 1.5 per cent; temporary neurologic deficit, 1 per cent; and temporary cranial nerve injury, 1 per cent. Analysis of these patients and of the literature supports an aggressive approach to carotid endarterectomy for patients with focal transient ischemic attacks and a more cautious approach for patients with prior stroke or asymptomatic stenoses.
