Methods and materials

During 2015-2018 years 10 patients with extracranial carotid aneurysms were examined at radiology department. Examination included an ultrasound (GE Vivid 7) and subsequent CTA (non-contrast study and two contrast phases Philips iCT 256 slice). Contrast bolus injection was performed with 50 ml of non-ionic iodine contrast media at a rate of 4–5 ml/sec. 7 of 10 patients underwent reconstructive surgery on the affected carotid artery segment.

Analysis of the state of the brachiocephalic arteries (at the levels of scanning) was carried out according to a special protocol. Dedicated description of aneurysm included:

• Localization of changes

• Characteristics and dimensions (diameter of the "neck", the maximum size of the aneurysm, the distance from the "neck" to the bottom of the aneurysm)

• The state of the aneurysm lumen

• Condition of the aneurysm walls
