Inclusion criteria
Inclusion criteria: Patients with high-grade asymptomatic> 60-70% stenosis of the ACI according to NASCET criteria and flow-velocity of over 250-300 cm / s, as well as symptomatic patients with over 50-99% stenosis of the ACI and flow-velocity of over 200 cm / s are examined. Our inclusion criteria thus correspond to the group for which there is an indication for performing a CEA according to the guidelines of the "European Society for Vascular Surgery".
Exclusion criteria
Exclusion criteria: - Serious systemic inherited or acquired diseases, especially psychiatric or neurological diseases. - Contraindications to performing an MRI scan. - Previous operations or carotid interventions or interventions that significantly affect carotid anatomy, such as radiation in the neck area. - Patients who show severe morphological changes in the MR examination.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| In thid study we want to investigate how the connectivity of he areas associated with cognitive performance after performing a CEA changed with special attention to the DMN. We also want to measure changes in the volumes of the hippocampus and frontal, parietal and temporal cortex areas and correlate both connectivity and volumetry with neuropsychological tests. | — |
