Carotisendarteriëctomie voor een asymptomatische stenose

- Carotid endarterectomy (CE) is of proven value for patients with a high-grade symptomatic stenosis of the internal carotid artery (ICA). Recently, the Asymptomatic Carotid Atherosclerosis Study group showed that in patients with an asymptomatic ICA stenosis of more than 60, CE caused an absolute risk reduction of perioperative death or stroke during 5 year follow-up of 5.4 (95 confidence interval: 3.0-7.8). Half of these strokes were disabling. The number needed to treat to save one patient from death within 30 days or stroke within in the following 5 years was 19. Further studies are needed to isolate a group of patients that will substantially benefit from the operation. CE is probably most effective in males under 75 years of age. A low surgical morbidity and mortality is an absolute prerequisite to justify CE for an asymptomatic ICA stenosis.
