Key result

Carotid duplex scanning criteria (PSVICA/CCA and EDVICA) reliably predicted carotid stenoses exceeding 50% and 70% as defined by NASCET arteriographic criteria.

Why the study?

Does carotid duplex scanning accurately predict internal carotid artery stenoses exceeding 50% and 70% compared to digital subtraction cerebral arteriography in surgical candidates?

Population

141 patients (264 carotid arteries) considered surgical candidates for carotid endarterectomy

Structured PICO

Does carotid duplex scanning accurately predict internal carotid artery stenoses exceeding 50% and 70% compared to digital subtraction cerebral arteriography in surgical candidates?

Population

141 patients (264 carotid arteries) considered surgical candidates for carotid endarterectomy, prospectively studied over a 2-year period.

Exposure

Carotid duplex scanning (measuring peak systolic velocity and end-diastolic velocity in internal and common carotid arteries, and calculating ICA/CCA velocity ratios)

Comparator

Digital subtraction cerebral arteriography using NASCET criteria

Outcome

Prediction of carotid stenoses exceeding 50% and 70% (measured by sensitivity, specificity, positive and negative predictive values, and accuracy)surrogate

Carotid duplex scanning using multiple velocity criteria can reliably predict clinically significant internal carotid artery stenoses as defined by NASCET arteriographic criteria.

Limitations

These criteria should be independently validated by other vascular laboratories.
Criteria require independent validation by other vascular laboratories

Kreske et al. (1999) conducted an observational in Carotid artery stenosis (n=141). Carotid duplex scanning vs. Digital subtraction cerebral arteriography was evaluated on Prediction of carotid stenoses exceeding 50% and 70% as defined by NASCET arteriographic criteria. Carotid duplex scanning criteria (PSVICA/CCA and EDVICA) reliably predicted carotid stenoses exceeding 50% and 70% as defined by NASCET arteriographic criteria.
