What does this research mean for the field?

The ratio of internal carotid systolic velocity at the carotid bulb to the distal internal carotid systolic velocity (ICSV/DICSV) significantly improves the Doppler detection of carotid artery stenosis of 60% or greater, particularly when the ICSV is 100 cm/sec or greater. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Implication

May refine Doppler grading of carotid stenosis when ICSV ≥100 cm/sec; leaves open prospective validation before practice change.

Structured PICO

Does the ICSV/DICSV ratio improve the detection of carotid artery stenosis compared to other Doppler measurements?

Population

211 patients (365 carotid arteries evaluated, with a subgroup of 258 carotid arteries having an internal carotid systolic velocity ≥100 cm/sec)

Intervention

Internal carotid systolic velocity (ICSV) to distal internal carotid systolic velocity (DICSV) ratio measured by Doppler sonography

Comparator

Other Doppler measurements (ICSV, ICSV/CCSV ratio, and ICDV) with carotid angiography as the reference standard

Outcome

Detection of carotid artery stenosis ≥60% and ≥70%surrogate

The ICSV/DICSV ratio improves the Doppler detection of significant carotid artery stenosis when the internal carotid systolic velocity is ≥100 cm/sec.
