Carotid endarterectomy under regional (conductive) anesthesia

Area of Science:

• Vascular Surgery
• Neurology
• Anesthesiology

Background:

• Carotid endarterectomy is a key procedure for preventing strokes caused by carotid bifurcation arteriosclerotic disease.
• Assessing the safety and complication origins of regional anesthesia for this procedure is crucial.

Purpose of the Study:

• To evaluate the safety and efficacy of regional anesthesia for carotid endarterectomy.
• To differentiate between embolic and ischemic origins of neurologic complications during the procedure.

Main Methods:

• Retrospective review of 314 carotid endarterectomies.
• Analysis of perioperative mortality and neurologic complication rates.
• Comparison of complication incidence between regional and general anesthesia.

Main Results:

• Perioperative mortality was 0.88% and neurologic complications occurred in 3.1% of patients.
• Regional anesthesia demonstrated a significantly lower incidence of non-neurologic complications (2.8%) compared to general anesthesia (12.9%).
• Observations suggested embolization as the cause for approximately half of the neurologic deficits.

Conclusions:

• Carotid endarterectomy performed under regional anesthesia is a safe and reliable method.
• Regional anesthesia offers a favorable safety profile with reduced non-neurologic complications.
• Further investigation into the embolic nature of neurologic deficits is warranted.
