Aims and objectives
Extracranial carotid arteryaneurysm isa very rare pathology with frequency no more than 4% of peripheral artery aneurysms [1-3].
Aneurysms of the carotid arteries have a variety of etiological factors including genetically determined anomaly of the connective tissue,
traumatic damage and other factors [1,4].
Clinical symptoms of extracranial carotid aneurysms vary from asymptomatic course to the feeling of pulsating lesion in the neck,
cerebral circulation disorders (stroke) or rupture of the aneurysm [5-9].
Well-timed diagnosis and subsequent treatment of this pathology are actual problems...
Methods and materials
During 2015-2018 years 10 patients with extracranial carotidaneurysmswereexamined atradiology 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.
In our study 9 patients had aneurysm of the internal carotid artery.
Aneurysm of the common carotid artery was observed in one case. All aneurysms had a saccular shape.
We divided patients in our study in 2 groups according to the state of aneurysm walls.
Thus signs of complicated course were observed in 6 patients (60% of cases).
Uncomplicated course of extracranial carotid aneurysm (4 cases)
Patients in this group had complaints of high blood pressure(3 patients) and ischemic stroke(1 patient).

CTA is highly informative in identifying and assessing the state of the walls of extracranial carotid artery aneurysms.
As opposed to ultrasound investigations,
CTA revealed extracranial carotid aneurysms in 100% of cases,
including in the uppermost partof cervical segment of the internal carotid artery.
Most of the aneurysms (60%) had complicated course,
which was essential for subsequent surgery.
