Summary
Carotid endarterectomy shows significantly reduced perioperative complications compared to historical data. Improved surgical techniques and patient evaluation contribute to these favorable outcomes in vascular surgery.
Area of Science:
- Vascular Surgery
- Neurology
- Cardiology
Background:
- Recent studies suggest lower perioperative neurologic events in carotid endarterectomy compared to 1990s trials.
- No significant difference observed between high and low-risk patients in these series.
Purpose of the Study:
- To evaluate the perioperative complication rates of carotid endarterectomy.
- To compare current outcomes with historical data and assess the safety of the procedure.
Main Methods:
- Prospective data collection of 8743 carotid endarterectomy procedures from 1992-2009.
- Detailed recording of surgical techniques (eversion, patch closure) and perioperative events.
- Analysis of mortality, stroke, hematoma, and cranial nerve injury rates.
Main Results:
- Perioperative mortality was 0.32% (myocardial infarction most common).
- Neurological morbidity was 1.04% (major/minor strokes).
- Cervical hematoma (2.3%) and cranial nerve lesions (3.0%) required intervention/were observed.
Conclusions:
- Carotid endarterectomy demonstrates reduced perioperative complications compared to historical literature.
- Improved preoperative evaluation, surgical experience, and techniques contribute to better outcomes.
- Real-world carotid endarterectomy results should be benchmarked against carotid angioplasty and stenting for extracranial cerebrovascular disease treatment.
