Implication

Supports duplex scanning for carotid disease detection in selected patients; leaves open validation for severity grading across broader populations.

Structured PICO

Does duplex ultrasonic scanning accurately detect and categorize the severity of carotid artery atherosclerosis compared to cerebral arteriography in patients with suspected extracranial carotid artery disease?

P
Population
750 patients with suspected extracranial carotid artery disease evaluated between January 1978 and January 1980. A subset of 135 patients (18%) underwent cerebral arteriography.
I
Intervention
Duplex ultrasonic scanning (real-time B-mode imaging with single-gate, variable-range pulsed Doppler and spectral analysis)
C
Comparator
Cerebral arteriography (biplanar views of the carotid bifurcation)
O
Outcome
Detection and categorization of the severity of carotid artery atherosclerosis (degree of stenosis)surrogate

Duplex ultrasonic scanning is highly accurate (97%) in detecting carotid artery disease compared to cerebral arteriography, though it is less accurate for very mild (<10%) stenosis.

Limitations

  • The technique was less accurate with lesions that produced less than 10% diameter reduction.
