Summary
Internal carotid endarterectomy for atherosclerotic lesions is a common surgery. Antiplatelet drugs effectively prevent thrombosis, improving patient outcomes and reducing risks associated with this procedure.
Area of Science:
- Vascular Surgery
- Neurology
- Cardiology
Background:
- Carotid artery reconstructive surgery is a prevalent procedure in peripheral vascular surgery.
- Advances in surgical indications, monitoring, and anesthesia have reduced risks of internal carotid endarterectomy.
Purpose of the Study:
- To evaluate the safety and efficacy of extracranial carotid reconstructive surgery.
- To assess outcomes in patients undergoing carotid endarterectomy for atherosclerotic lesions.
Main Methods:
- Review of 2,857 operations performed on 2,087 patients between 1976 and 1985.
- Analysis of indications for surgery (hemispheric symptoms vs. asymptomatic stenosis).
- Evaluation of postoperative complications, particularly thrombosis, and the impact of antiplatelet drugs.
Main Results:
- Surgery was recommended for hemispheric symptoms in 58% and asymptomatic stenosis in 14% of cases.
- Postoperative hemiparesis occurred in 24 patients; 18 were associated with operative site thrombosis.
- Antiplatelet drugs demonstrated effectiveness in preventing operative site thrombosis in the latter part of the study.
- Operative mortality was 1.5% over the study period.
Conclusions:
- Extracranial carotid reconstructive surgery is a safe and effective procedure for selected patients.
- Antiplatelet therapy is crucial for preventing postoperative thrombosis.
- Long-term follow-up shows a high rate of survival and symptom-free status for patients.
