Carotid Stenosis: Utility of Diagnostic Angiography

Carotid artery stenosis is frequently diagnosed through screening tests with non-invasive imaging. Because of differences noted between the various modalities, we sought to investigate our experience comparing non-invasive imaging (ultrasound, CT angiography, MR angiography) with invasive imaging (digital subtraction angiography). In a multi-center retrospective analysis, 249 carotid vessels were reviewed based on angiography with the associated non-invasive imaging. Overall, medical or surgical decision management was changed in 43% (107/243) of cases investigated with digital subtraction angiography due to a discrepancy between the measured percentage stenosis.
