ABSTRACT
BACKGROUND:
In asymptomatic patients presenting with significant internal carotid artery (ICA) stenoses undergoing endovascular revascularization, a selective angiography before stenting (CAS) is required. Sometimes, angiographic findings could be discordant from non-invasive assessment and a tool able to evaluate functional relevance of the stenosis could be of value. We sought to evaluate the usefulness of quantitative flow ratio (QFR) as angiography-based tool for functional assessment of ICA stenoses.METHODS:
We prospectively enrolled 50 asymptomatic patients undergoing CAS. Peak systolic velocity (PSV, cm/s) assessed at color Doppler echocardiography was used to identify significant stenoses (PSV >125 cm/s). At angiography, assessment of ICA stenosis was obtained visually (%DSRESULTS:
At linear regression analysis, QFR significantly correlated with PSV (r2=0.52, P<0.001) as well as with %DSCONCLUSIONS:
This study suggest the potential benefit of adopting QFR for functional assessment of extracranial ICA stenoses. These data should be validated in larger studies.
