Minimizing the risks of carotid endarterectomy

Area of Science:

• Vascular Surgery
• Neurology
• Anesthesiology

Background:

• Carotid endarterectomy aims to reduce stroke risk but carries inherent mortality and neurologic complication risks.
• Optimal surgical methods and patient selection are crucial for improving outcomes.

Purpose of the Study:

• To determine optimal methods and guidelines for reducing mortality and neurologic complications in carotid endarterectomy.
• To evaluate the efficacy of local anesthesia and continuous neurologic monitoring.

Main Methods:

• 570 carotid endarterectomies were analyzed, with 84% performed under local anesthesia.
• Carotid stump pressures (CSPs) and CSP/brachial blood pressure (BBP) index were measured in awake patients.
• Selective shunting criteria based on CSP and CSP/BBP index were established.

Main Results:

• Local anesthesia was associated with a significantly lower mortality rate (0.2%).
• CSPs and CSP/BBP index proved reliable indicators for selective shunting, reducing shunt necessity.
• Overall mortality was 0.7% and neurologic complications were 0.9% across all procedures.

Conclusions:

• Local anesthesia and continuous neurologic monitoring enhance patient safety during carotid endarterectomy.
• CSPs and CSP/BBP index are effective tools for guiding selective shunting decisions.
• Careful patient selection and adherence to established guidelines can minimize risks associated with the procedure.
