Carotid endarterectomy. Complications and preoperative assessment of risk

Area of Science:

• Vascular Surgery
• Neurosurgery
• Cardiology

Background:

• Carotid endarterectomy is a crucial procedure for stroke prevention.
• Identifying patients at high risk for complications is essential for surgical decision-making.

Purpose of the Study:

• To present a system for grouping patients based on preoperative risk evaluation for carotid endarterectomy.
• To correlate patient risk factors with the incidence of primary complications, including myocardial infarction and neurologic deficit.

Main Methods:

• Patients were categorized into four groups based on neurologic stability, medical comorbidities, and angiographic findings.
• Risk stratification was based on preoperative assessment of these factors.

Main Results:

• Group 1 (neurologically stable, no risk factors): 1% complication risk.
• Group 2 (neurologically stable, angiographic risk): 2% complication risk.
• Group 3 (neurologically stable, medical illness): 7% complication risk, mainly cardiac.
• Group 4 (neurologically unstable): 10% risk of neurologic deficit.

Conclusions:

• A preoperative risk stratification system can effectively predict complications following carotid endarterectomy.
• Neurologic stability and the presence of medical comorbidities are significant predictors of surgical risk.
• This system aids in optimizing patient selection and management for carotid endarterectomy.
