A safe approach to carotid endarterectomy

Area of Science:

• Vascular Surgery
• Neurology
• Anesthesiology

Background:

• Stroke symptoms necessitate surgical intervention for many patients.
• Carotid endarterectomy is a common procedure to prevent ischemic events.
• Optimizing anesthesia and monitoring during carotid endarterectomy is crucial for patient outcomes.

Purpose of the Study:

• To evaluate the safety and efficacy of carotid endarterectomy for stroke symptom relief.
• To assess the outcomes of using general hypercarbia anesthesia with arterial pCO2 monitoring.
• To determine the complication and mortality rates associated with this surgical approach.

Main Methods:

• 155 carotid endarterectomies were performed on 124 patients.
• General hypercarbia anesthesia was employed.
• Arterial pCO2 monitoring was utilized without internal bypass shunt or hypothermia.

Main Results:

• A low rate of significant permanent post-operative complications was observed (1.9%).
• Two postoperative deaths occurred, with one attributed to myocardial infarction.
• The procedure was effective in relieving stroke symptoms.

Conclusions:

• Carotid endarterectomy under general hypercarbia anesthesia with arterial pCO2 monitoring is a safe and effective treatment for stroke symptoms.
• The technique is associated with low complication and mortality rates.
• This approach avoids the need for internal bypass shunt or hypothermia.
