Key result
A modified Doppler ultrasonic assessment correctly identified significant internal carotid artery stenosis or occlusion in 98.7% of vessels, compared to 64% detection by the classic compression test.
Why the study?

Supports modified Doppler for carotid stenosis detection; hypothesis-generating and requires prospective validation before practice change.
Observational
Does a modified Doppler cerebrovascular examination improve the detection of significant internal carotid artery stenosis compared to the classic temporal artery compression test?
Absolute Event Rate: 98.7% vs 64%
A refined Doppler ultrasound technique involving sequential compression of multiple arteries significantly improves the diagnostic accuracy for detecting internal carotid artery stenosis.
Barnes et al. (1977) conducted an observational in Extracranial carotid occlusive disease. Modified Doppler ultrasonic assessment vs. Classic temporal artery compression test was evaluated on Correct identification of significant (>50%) stenosis or occlusion of the internal carotid artery. A modified Doppler ultrasonic assessment correctly identified significant internal carotid artery stenosis or occlusion in 98.7% of vessels, compared to 64% detection by the classic compression test.
