Why the study?

What is the prevalence of atherosclerotic lesions at the carotid bifurcation detected by echo-Doppler in patients with asymptomatic neck bruits?

Key Points

To determine the prevalence of atherosclerotic lesions at the carotid bifurcation in patients with asymptomatic bruits.
Evaluated 71 patients referred for echo-Doppler scans
Classified internal carotid arteries based on stenosis degree
Used a spectral analysis system for evaluation.
84% of internal carotid arteries had stenosis of various degrees, with 16% being severe.
No lesions greater than 20% diameter reduction observed for low-neck bruits.
Total occlusion occurred in 2% of cases.

Structured PICO

What is the prevalence of atherosclerotic lesions at the carotid bifurcation detected by echo-Doppler in patients with asymptomatic neck bruits?

P

Population

71 patients (42 males, ages 19 to 84 years) with asymptomatic neck bruits referred for an echo-Doppler (duplex) scan. 59 patients had mid-neck or high-neck bruits (30 bilateral) and 12 had low-neck bruits (4 bilateral).

I

Intervention

Echo-Doppler (duplex) scan associated with spectral analysis

O

Outcome

Prevalence and severity of atherosclerotic lesions (stenosis) at the carotid bifurcationsurrogate

Echo-Doppler scanning effectively identifies significant carotid stenosis in patients with asymptomatic mid- or high-neck bruits, potentially reducing the need for invasive diagnostic procedures.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Mid- or high-neck bruits associate with carotid stenosis on echo-Doppler; leaves open location-specific screening value in larger cohorts.
