[Should certain carotid artery stenoses be surgically treated?].

Summary

Carotid endarterectomy may be justified for patients with symptomatic carotid stenosis or ulcerated plaques. Surgery offers a lower long-term stroke risk compared to medical management for specific patient groups.

Area of Science:

  • Vascular Surgery
  • Neurology
  • Cerebrovascular Disease

Context:

  • Carotid endarterectomy remains a debated procedure for managing extracranial carotid stenosis.
  • Understanding the risks and benefits is crucial for clinical decision-making.

Purpose:

  • To evaluate the morbidity-mortality rates of carotid endarterectomy.
  • To assess the long-term risk of ipsilateral cerebral infarction after surgery versus medical treatment.
  • To determine the influence of stenosis degree and ulceration on clinical outcomes.

Summary:

  • For asymptomatic stenosis, peri-operative morbidity-mortality was 4.22%, with long-term infarction rates of 0.34%/year (operated) vs. 0.50%/year (non-operated). Severe stenosis and ulcerations significantly increased non-operative stroke risk.
  • For symptomatic stenosis, peri-operative morbidity-mortality was 5.5%, with long-term infarction rates of 0.67%/year (operated) vs. 2.70%/year (non-operated).
  • Endarterectomy appears justified for ulcerated or symptomatic stenoses, but conclusions require consideration of surgical quality.

Impact:

  • Provides evidence to guide treatment decisions for carotid stenosis.
  • Highlights the importance of plaque characteristics (ulceration) in risk stratification.
  • Suggests that surgical outcomes are influenced by surgeon experience, a factor often underreported.
