Aim.
To investigate the clinical relevance of plaque’s morphological characteristics and distribution pattern using 3.0 T high-resolution magnetic resonance imaging (HRMRI) in patients with moderate or severe basilar artery (BA) atherosclerosis stenosis.
Materials and Methods.
Fifty-seven patients (33 symptomatic patients and 24 asymptomatic patients) were recruited for 3.0 T HRMRI scan; all of them had >50% stenosis on the BA.
The intraplaque hemorrhage (IPH), contrast-enhancement pattern, and distribution of BA plaques were compared between the symptomatic and asymptomatic groups.
Factors potentially associated with posterior ischemic stroke were calculated by multivariate analyses.
Results.
Enhancement of BA plaque was more frequently observed in symptomatic than in asymptomatic patients (27/33, 81.8% versus 11/24, 45.8%; p<0.01).
In multivariate regression analysis, plaque enhancement (OR = 7.193; 95% CI: 1.880–27.517; p=0.004) and smoking (OR = 4.402; 95% CI: 2.218–15.909; p=0.024) were found to be independent risk factors of posterior ischemic events in patients with BA stenosis >50%.
Plaques were mainly distributed at the ventral site (39.3%) or involved more than two arcs (21.2%) in the symptomatic group but were mainly distributed at left (33.3%) and right (25.0%) sites in the asymptomatic group.
