Key result
Carotid stenosis >50% was significantly associated with large infarcts on CT scan compared to <50% stenosis (70% vs 25%, p=0.003).
Why the study?
Does carotid Doppler evaluation correlate with infarct size on CT scan head in patients with transient ischemic attack and stroke?
Observational (n=100)
No

Absolute Event Rate: 70% vs 25%
p-value: p=0.003
Carotid Doppler is a highly sensitive non-invasive tool for detecting carotid stenosis, and the severity of stenosis significantly correlates with the size of cerebral infarcts on CT.

Supports link between carotid stenosis severity and infarct size; hypothesis-generating for Doppler use in TIA/stroke, needs prospective validation.
Malik Rajesh (2013) conducted an observational in Stroke and Transient Ischemic Attack (n=100). Carotid stenosis >50% vs. Carotid stenosis <50% was evaluated on Large infarct on CT scan head (p=0.003). Carotid stenosis >50% was significantly associated with large infarcts on CT scan compared to <50% stenosis (70% vs 25%, p=0.003).
