American Journal of Surgery
|April 1, 1977
Summary
Carotid endarterectomy has a 1.5% mortality rate, primarily from myocardial infarction. This study highlights risks including neurologic deficits and peripheral nerve injuries, emphasizing safe surgical techniques.
Area of Science:
- Vascular Surgery
- Neurology
- Surgical Outcomes
Background:
- Carotid endarterectomy is a critical procedure for preventing stroke.
- Understanding the associated risks is essential for patient safety and procedural refinement.
Purpose of the Study:
- To present the hazards and safeguards of carotid endarterectomy.
- To analyze outcomes in a consecutive patient series.
Main Methods:
- Review of 130 consecutive carotid endarterectomy cases over 14 months.
- Analysis of mortality, neurologic deficits, and peripheral nerve injuries.
Main Results:
- Mortality rate was 1.5% (due to myocardial infarction).
- Permanent neurologic deficit occurred in 1.5% of patients.
- Transient neurologic deficits (4.6%) resolved within 24 hours.
- Peripheral nerve injuries occurred in 12.3% of patients.
Conclusions:
- Carotid endarterectomy carries specific risks, including cardiovascular events and neurologic complications.
- Peripheral nerve injury is a notable complication requiring attention.
- Knowledge of local neurologic anatomy is crucial for minimizing surgical injury during dissection.
