Key result
Carotid angiography alters clinical management in ~30% of patients with suspected carotid stenosis.
Why the study?
The added value of carotid angiography over carotid duplex examination alone in altering clinical management of carotid artery stenosis was uncertain.
Does carotid angiography alter clinical management compared to duplex ultrasound alone in patients with suspected carotid artery stenosis?
Population
182 consecutive patients with suspected carotid artery stenosis undergoing duplex and angiography
Comparison
Carotid/cerebral angiography vs carotid artery duplex examination alone
Design
Retrospective cohort study

Angiography altered management in 30%; supports selective use but leaves open whether duplex alone suffices today.

Does carotid angiography alter clinical management compared to duplex ultrasound alone in patients with suspected carotid artery stenosis?
Carotid angiography provides additional information that alters clinical management in a substantial proportion of patients with suspected carotid stenosis compared to duplex ultrasound alone.
Long et al. (2001) conducted a cohort in Suspected carotid artery stenosis (n=182). Carotid angiography vs. Carotid duplex examination alone was evaluated on Alteration of clinical management plan. Carotid angiography provided additional information in 53% of patients and altered the clinical management plan in 30% (55/182) of patients with suspected carotid artery stenosis.
