Key result
Carotid ultrasound shows no difference versus DSA in detecting carotid artery stenosis.
Why the study?
This study aimed to compare the clinical value of carotid ultrasound and digital subtraction angiography for diagnosing carotid artery stenosis in patients with cerebral infarction.

How does carotid ultrasound compare to digital subtraction angiography in diagnosing carotid artery stenosis in patients with cerebral infarction?
Absolute Event Rate: 91.67% vs 96.67%
p-value: p=0.243
While carotid ultrasound is an effective and convenient screening tool for carotid artery stenosis, DSA provides more accurate assessment of the degree of stenosis and occlusion.
Chen et al. (2022) conducted a cohort in Cerebral infarction (n=60). Carotid ultrasound vs. Digital subtraction angiography (DSA) was evaluated on Carotid artery stenosis detection rate (p=0.243). Carotid ultrasound detected carotid artery stenosis in 91.67% of patients compared to 96.67% with digital subtraction angiography, showing no statistically significant difference.
