Comparative long-term results of patients with carotid artery stenosis
Insights
Thrombendarterectomy for internal carotid artery stenosis significantly improved patient outcomes. Operated patients experienced fewer neurological deficits and higher survival rates compared to conservative treatment over 10 years.
Area of Science:
- Vascular Surgery
- Neurology
- Clinical Outcomes Research
Background:
- Internal carotid artery stenosis poses a significant risk of stroke.
- Surgical intervention versus conservative management is a critical clinical decision.
Purpose of the Study:
- To compare the 10-year clinical outcomes of thrombendarterectomy versus conservative treatment for internal carotid artery stenosis.
Main Methods:
- A cohort of 78 patients with internal carotid artery stenosis was analyzed.
- 46 patients underwent thrombendarterectomy; 32 received conservative management.
- Clinical follow-up extended over a 10-year period.
Main Results:
- Operated patients had a 3% permanent neurologic deficit rate versus 69% in nonoperated patients.
- Physical capacity improved in 92% of operated patients vs. 64% conservatively.
- 10-year survival was 78% for operated patients and 34% for nonoperated patients.
Conclusions:
- Thrombendarterectomy is a highly effective treatment for internal carotid artery stenosis, significantly reducing morbidity and mortality.
- Surgical intervention offers superior long-term outcomes compared to conservative management for this condition.
Abstract:
Of 78 patients with an internal carotid artery stenosis a thrombendarterectomy was performed in 46 patients whereas 32 patients were treated by conservative methods. The clinical follow-up over a period of 10 years was investigated. The percentage of patients who received drugs for anticoagulation was equal in both groups. Operated patients acquired a permanent neurologic deficit in 3% and nonoperated patients in 69%. The physical capacity improved in 92% of the operated and in 64% of patients treated conservatively. At the time of reexamination 78% of the operated and 34% of the nonoperated patients were living. The cause of death was cardiac in 42% of both groups and cerebral in 11% of the operated and in 32% of the nonoperated patients.
