Summary
Carotid endarterectomy in South Australia showed acceptable overall morbidity and mortality. However, patients with a prior stroke faced significantly higher risks, suggesting careful consideration for this subgroup.
Area of Science:
- Vascular Surgery
- Neurology
- Public Health
Background:
- Carotid endarterectomy (CEA) is a procedure to prevent stroke.
- Assessing the safety and effectiveness of CEA is crucial for patient outcomes.
Purpose of the Study:
- To evaluate the operative morbidity and mortality rates of carotid endarterectomy (CEA) in South Australia.
- To identify patient subgroups with potentially higher risks associated with CEA.
Main Methods:
- A prospective study of consecutive patients undergoing CEA in South Australia.
- Independent neurological assessments before and after surgery, with follow-up at 6 and 12 months.
Main Results:
- Overall perioperative death and stroke rate was 6.3%.
- Postoperative stroke occurred in 5.9% of patients, with a 1.3% mortality rate.
- Morbidity was higher in patients with a preceding stroke (16.7%) compared to asymptomatic patients (3.4%).
Conclusions:
- Carotid endarterectomy morbidity and mortality in South Australia are acceptable by global standards.
- The procedure's risk in patients with a prior stroke is notably high.
- CEA did not appear to reduce the expected incidence of stroke and death compared to one year of untreated disease.
