Introduction: Silent brain infarctions (SBI) are necrotic lesions which occur due to acute reduction of blod flow. Although they do
not cause acute neurological syndrome, potential consequences can be vascular dementia, cognitive and psychiatric disorders,
increased risk of clinically manifest infarct and fatal outcome.
Тhe Aim: The aim of this study was to determine and analyze the sensitivity of MRI in diagnostic of SBI based on their size and
signal intensity, using MRI images made immediately after and 60 days after carotid stenting. Moreover, to determine the
incidence of new SBI after stenting and correlation between their localization and the placement site of endovascular stent.
Material and Methods: This retrospective study included endocranium MRI of 32 patients who underwent a carotid stenting
procedure. MRI images were made after the stenting procedure and the imaging was repeated after 60 days and one more on the
patient group in which we found existing SBIs on the previous imaging. Analysis of images was performed on the ADC/DWI, T2 /
FLAIR and FLAIR CUBE sequences using PACS software. AP and LL diameters were measured and the average ADC coefficient after
intervention and also the average signal intensity after 60 days in the lesion region on FLAIR CUBE sequences. Statistical analysis
was performed using SPSS Statistics 23.0.0.
Results: The incidence of SBI caused due to intervention is 37.5%. There was a statistically significant difference between the ADC
coefficient and the signal intensity in both the lesion region and the size of lesions.
Conclusion: The high frequency of SBI after the carotid stenting disfavor this procedure as an option for the treatment of the
carotid artery atherosclerotic diseases. We concluded that only SBI larger than 5 mm have the expected values of the ADC and
signal intensity of ischemic changes, and because of that, only these changes can be considered as a real SBI.
