Abstract EN
This retrospective study included 65 patients who underwent multidetector computed tomography (MDCT) carotid angiography; 28 patients were <70 years old (group 1), and 37 were ≥70 years old (group 2).
Each low-attenuation (<30 Hounsfield units [HU]) plaque volume (LPV) and total uncalcified plaque volume ([TUPV] ≤150 HU) were semiautomatically measured on each aortic arch and internal carotid artery (ICA) curved planar reformations (CPR), using MDCT angiographic data.
Correlation coefficients were employed to assess the impact of each plaque volume on various factors including ICA stenosis.
The correlations (r > 0.5) were observed between aortic LPV and each ICA stenosis ratio and >30% stenosis in group 1, between aortic TUPV and male gender in group 1, and between ICA-TUPV and each aortic TUPV or the largest plaque thickness in group 2.
Marginal correlations were observed between hyperlipidemia and aortic LPV and ICA-TUPV in group 1.
There was no association between cerebral infarction and the aortic and ICA plaques.
Both the aortic arch and ICA plaque volumes can be measured clinically.
The increasing aortic LPV may be a significant factor associated with the development of ICA stenosis in patients younger than 70 years old.
