Key result
Carotid Doppler ultrasound had a positive predictive value of 80% in symptomatic and 59% in asymptomatic patients for identifying appropriate candidates for carotid intervention.

Caution against sole Doppler reliance for intervention; leaves open accuracy versus angiography in routine observational care.

Does carotid Doppler ultrasound accurately identify patients for carotid intervention compared to conventional angiography in general practice settings?
Carotid Doppler ultrasound performed in general practice has a high false-positive rate and should not be used as the sole basis for selecting patients for carotid intervention without confirmatory angiography.
Qureshi et al. (2001) conducted an observational in Carotid artery stenosis (n=130). Carotid Doppler ultrasound vs. Conventional angiography was evaluated on Positive predictive value for identifying appropriate symptomatic candidates for carotid intervention (angiographic stenosis ≥50%). Carotid Doppler ultrasound had a positive predictive value of 80% in symptomatic and 59% in asymptomatic patients for identifying appropriate candidates for carotid intervention.
