Abstract

Objective: To investigate computed tomography (CT) features of the internal carotid artery (ICA) extracranial of patients with acute cerebral infarct (ACI). Methods: Retrospective study of 50 patients with ACI admitted and treated at People's Hospital 115 from january 2023 to december 2023. Results: The study involted 35 men, 15 women, with an average age of 64,76 ± 11,43 years. The location of ACI lesions in the middle cerebral artery region accounted for 100% (60% on the right side, 40% on the left side). The rate of stenosis of the extracranial ICA on the same side as ACI increased gradually from the distal segment (10%) to the middle segment (20%) and was highest in the proximal segment (70%). The rates of calcified plaque, soft plaque, and mixed plaque were aproximately equal. The size of plaque was 4,81 ± 1,05 mm in thickness and 20,16 ± 2,27 mm in length. Common features of high-risk plaque were: arterial wall enhancement (90%), perivascular fat infiltration (86%), remodeling index (74%). The average diameter lumen diameter of the ICA on the same side ACI was 1,62 ± 0,60 mm, which was statistically significant narrower than that on the opposite side (4,74 ± 0,83 mm)  (p < 0,001). Conclusion: Plaque characteristics of ICA on CT scan, especially high-risk plaque, help improve the quality of treatment and stroke prevention for patients
