Comparative assessment of the possibilities of multispiral computer tomography and ultrasound dopplerography in the verification of atherosclerotic lesions of major vessels

The purpose — to compare the diagnostic potential of multispiral computer tomography and ultrasound dopplerography in the assessment of atherosclerotic lesions of the cerebral arteries in metabolic syndrome. Material and methods. The study included 78 patients. The group consisted of 44 men (56,4%) and 34 women (43,6%); the average age was 62 ± 1,2 years. Coronary heart disease was detected in 54 (69,2%), and no signs were registered in 24 (30,8%). Anamnestically, 19 (24,4%) people were diagnosed with a stroke, and 18 (23%) people had a myocardial infarction. 42 people (53,8%) had verified dyscirculatory encephalopathy of various degrees. 34 (43,6%) people suffered from hypertension. 42 people had disorders of carbohydrate metabolism: 12 (15,3%) — type 2 diabetes, 30 (38,4%) — metabolic syndrome. The patients were divided into 3 groups: 1) persons without metabolic syndrome — 48 people (61.5% of the total number of examined); 2) persons with metabolic syndrome without type 2 diabetes — 18 people (23,1% of the total number of examined); 3) persons with type 2 diabetes — 12 people (15,4% of the total number of examined). Results. Atherosclerotic plaques in the carotid arteries were detected in 78 people by multispiral computer tomography and in 51 patients by ultrasound dopplerography of these vessels. Conclusions. In general, the use of multispiral computer tomography to detect atherosclerotic lesions of the vascular bed is the most preferable in comparison with ultrasound dopplerography, especially in patients with a high risk of cardiovascular events. While for patients who do not belong to this group, ultrasound dopplerography (a simple, accessible, informative technique) can be used as the primary screening.
