Why the study?

Does combined continuous wave Doppler examination improve the detection of extracranial carotid disease compared to periorbital Doppler alone in patients with cerebrovascular disease?

Population

333 patients (431 vessels) with cerebrovascular disease in all stages

Comparison

Combined continuous wave Doppler examination vs Periorbital Doppler test alone

Design

Cross-sectional

Implication

May improve noninvasive detection of significant carotid stenosis; leaves open validation against angiography and impact on outcomes.

Does combined continuous wave Doppler examination improve the detection of extracranial carotid disease compared to periorbital Doppler alone in patients with cerebrovascular disease?

Population

333 patients (431 vessels) with cerebrovascular disease in all stages

Intervention

Combined continuous wave Doppler examination (periorbital Doppler test together with insonation of the carotid arteries in the neck)

Comparator

Periorbital Doppler test alone (both compared to subsequent arteriography as the reference standard)

Outcome

Detection of extracranial obstructive (>50%) carotid disease (sensitivity and specificity)surrogate

Combined continuous wave Doppler examination is highly superior to periorbital Doppler alone for detecting significant extracranial carotid disease, achieving 100% sensitivity.

Limitations

Non-obstructive plaques could not be detected or excluded by either Doppler test.
