Key result
Lacunar infarct patients had significantly less severe carotid stenosis compared to non-lacunar infarct patients (p<0.001).
Why the study?
Does the degree of carotid stenosis and the effect of carotid surgery differ between patients with lacunar versus non-lacunar infarcts?
Cohort (n=626)
Yes
Does the degree of carotid stenosis and the effect of carotid surgery differ between patients with lacunar versus non-lacunar infarcts?
p-value: p=<0.001
Severe carotid stenosis in lacunar infarct patients is likely incidental, suggesting these infarcts are primarily due to intracranial small-vessel disease rather than carotid thromboembolism.
No takes yet. Share an insight, caveat, or question.
Supports small-vessel etiology in lacunar infarcts; leaves open whether carotid surgery benefits this subgroup.
Boiten et al. (2007) conducted a cohort in Ischaemic stroke (n=626). Lacunar infarct vs. Non-lacunar infarct was evaluated on Degree of carotid stenosis (p=<0.001). Lacunar infarct patients had significantly less severe carotid stenosis compared to non-lacunar infarct patients (p<0.001).
