Abstract:
Objective:To investigate the evaluation value of optical coherence tomography (OCT) for carotid atherosclerotic plaques.Methods:Patients with carotid atherosclerotic stenosis underwent digital subtraction angiography (DSA) and OCT in the Affiliated Hospital of Jining Medical College from January 2020 to January 2022 were retrospectively enrolled. The demographics, baseline clinical data, DSA and OCT imaging data of the symptomatic group and the asymptomatic group were compared. Multivariate logistic regression analysis was used to determine the independent risk factors for symptomatic carotid atherosclerotic stenosis. Results:A total of 39 patients were enrollded, including 21 in the symptomatic group and 18 in the asymptomatic group. The detection rate of fibrous plaque in the symptomatic group was significantly lower than that in the asymptomatic group (38.1% vs. 77.78%; P=0.023), while the detection rate of plaque rupture (38.1% vs. 5.56%; P=0.023) and macrophage infiltration (42.86% vs. 11.11%; P=0.037) was significantly higher than that in the asymptomatic group. Multivariate logistic regression analysis showed that plaque rupture (odds ratio 6.982, 95% confidence interval 1.068-45.660; P=0.043) and macrophage infiltration (odds ratio 6.480, 95% confidence interval 1.009-41.625; P=0.049) were significantly independently associated with the symptomatic carotid atherosclerotic stenosis. Conclusions:OCT is of value in evaluating the plaque characteristics of carotid atherosclerotic stenosis. Plaque rupture and macrophage infiltration are the independent risk factors for symptomatic carotid atherosclerotic stenosis.
