Insights
Carotid endarterectomy (CEA) is a safe procedure for stroke prevention. This study shows CEA has acceptable stroke and mortality rates, with long-term benefits in reducing late strokes.
Area of Science:
- Vascular Surgery
- Neurology
- Cardiovascular Medicine
Background:
- Cerebrovascular disease poses a significant health risk.
- Carotid endarterectomy (CEA) is a common surgical intervention for symptomatic carotid artery stenosis.
- Evaluating the safety and long-term efficacy of CEA is crucial for patient management.
Purpose of the Study:
- To assess the perioperative and long-term outcomes of carotid endarterectomy (CEA).
- To determine the morbidity and mortality rates associated with CEA.
- To evaluate the durability of CEA in preventing recurrent stroke.
Main Methods:
- A retrospective review of 324 carotid endarterectomies (CEAs) performed on 303 patients over five years.
- Analysis of perioperative complications, including stroke and mortality within 30 days.
- Long-term follow-up including clinical assessment and duplex ultrasound for restenosis.
Main Results:
- The combined perioperative stroke and mortality rate was 2.8%.
- Common complications included TIA (1.9%), cranial nerve injury (3.1%), and wound hematoma (6.5%).
- Late stroke occurred in 3.9% of patients, with 92% of arteries showing minimal restenosis (<30%) on follow-up.
Conclusions:
- Carotid endarterectomy (CEA) can be performed with acceptable morbidity and mortality.
- CEA is a durable procedure that significantly reduces the risk of late stroke.
- The findings support CEA as an effective treatment for selected patients with symptomatic carotid artery disease.
Abstract:
Three hundred twenty-four carotid endarterectomies (CEAs) were performed on 303 patients over 5 years. Sixty per cent of the patients were symptomatic with completed stroke (36.4%), amaurosis fugax (35.4%) or transient ischemic attack (TIA) (50.5%). Some patients had multiple symptoms. Perioperative stroke occurred in four patients (1.2%) and 30-day mortality in five (1.5%). The combined stroke-mortality rate was 2.8 per cent. Other postoperative complications included TIA (1.9%), cranial nerve injury (3.1%), wound hematoma (6.5%), and hypertensive reperfusion syndrome (9.6%). Ten early reoperations were performed for wound hematoma (7) or technical problems (3). Follow-up of 284 CEAs (88%) at a means of 31 months revealed 33 late deaths, with two due to stroke. Late strokes occurred in 11 patients (3.9%). Five late strokes were ipsilateral (1.8%) and six were contralateral (2.1%) to the operated carotid artery. Ninety-seven carotid arteries were evaluated by duplex ultrasound scanning at a mean postoperative interval of 27.2 months. Ninety-two per cent had 0-30 per cent restenosis, 5 per cent had 40 per cent to 60 per cent restenosis and 3 per cent had 70 per cent or greater restenosis. The authors conclude that CEA can be performed with acceptable morbidity and mortality rates and that it is a durable operation that reduces the risk of late stroke.
