Abstract:
Objective:To explore the value of ultrasound elastography (USE) in evaluating the stability and prognosis of carotid plaque (CP) in patients with cerebral infarction(CI).Methods:A total of 94 patients with CI admitted to Dongying District People′s Hospital of Dongying City from January 2022 to December 2023 were retrospectively selected as the study objects, all of whom were treated with carotid artery dissection. The presence of CP was confirmed by pathological examination. The head and neck of patients were examined by conventional ultrasound and USE before surgery, respectively, and the diagnostic value of the two methods on CP stability was compared. The difference of strain value and strain rate among different plaque types was compared, and the correlation between different plaque types and the score of ESSEN Stroke Risk Scale (ESRS) was analyzed.Results:The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of conventional ultrasonic detection of CP were 75.00%, 71.43%, 74.00%, 87.10% and 52.63%; and of USE were 90.28%, 89.29%, 90.00%, 95.59%, 78.13%. The strain values and strain rates of stable plaques were lower than those of vulnerable plaques : (0.73 ± 0.11) × 10 3 vs. (2.42 ± 0.57) × 10 3, (6.57 ± 0.84) s -1 vs. (9.36 ± 2.55) s -1, there were statistical differences ( P<0.01). The ESRS scores of patients with vulnerable plaques were mostly ≥3 scores, and those with stable plaques were mostly<3 scores, there was statistical differences ( P<0.01). The scores of National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) 3 months after the onset of stable plaque were lower than those of vulnerable plaque patients: (26.80 ± 8.47) scores vs. (34.67 ± 8.98) scores, (3.97 ± 0.84) scores vs. (4.55 ± 1.61) scores, there were statistical differences ( P<0.01 or <0.05). Conclusions:USE has significant advantages in detecting CP stability in CI patients, which can efficiently and accurately assess the risk of plaque and provide important information for clinical use.
