ABSTRACT
OBJECTIVE:
This study aimed to validate the efficiency of Doppler ultrasonography for predicting the innominate, subclavian, and common carotid artery stenosis.METHODS:
This retrospective multicenter study between 2013 and 2022 enrolled 636 patients who underwent carotid Doppler ultrasonography and subsequent digital subtraction angiography. And 58 innominate artery stenosis, 147 common carotid artery stenosis, and 154 subclavian artery stenosis were included. The peak systolic velocity at innominate, subclavian, and common carotid artery, and velocity ratios of innominate artery to common carotid artery, innominate artery to subclavian artery, and common carotid artery to internal carotid artery were measured or calculated. The threshold values were determined using receiver operating characteristic analysis.RESULTS:
The threshold values of innominate artery stenosis were peak systolic velocity >206 cm/s (sensitivity 82.8%; specificity 91.4%) to predict ≥50% stenosis and >285 cm/s (sensitivity 89.2%; specificity 94.9%) to predict ≥70% stenosis. The threshold values of common carotid artery stenosis were peak systolic velocity >175 cm/s (sensitivity 78.2%; specificity 91.9%) to predict ≥50% stenosis and >255 cm/s (sensitivity 87.1%; specificity 87.2%) to predict ≥70% stenosis. The threshold values of subclavian artery stenosis were peak systolic velocity >200 cm/s (sensitivity 68.2%; specificity 84.4%) to predict ≥50% stenosis and >305 cm/s (sensitivity 57.9%; specificity 91.4%) to predict ≥70% stenosis.CONCLUSIONS:
Symptomatic patients with ultrasonic parameters of velocity at innominate artery ≥206 cm/s, velocity at common carotid artery ≥175 cm/s, or velocity at subclavian artery ≥200 cm/s need to be considered for further verification and whether revascularization is necessary.Palabras clave
