Abstract

In clinical practice the combined atherosclerotic lesions of several arterial regions are observed twice often in comparison with the isolated lesions. About 25 % of cases of multifocal stenoses are significant (> 50 %) and demand surgical correction. For the purpose of definition of surgical tactics (staging and sequence of revascularization of each region), and tracking of results of treatment, high-informative, available and, as possible, noninvasive diagnostic methods are necessary. Ultrasonic visualization of the arteries is one of such methods. However, so far an X-ray angiography (AG) remains the conventional method of «the gold standard». The screening part is traditionally assigned to the ultrasonic duplex scanning (USDS). Recently several authors report about a successful application of USDS, in a combination with magnetic resonance imaging and/or computed tomography or independently, as a decisive method before operation. The purpose of the current study was to compare the USDS and AG of low extremity arteries in terms of their sensitivity and specificity in patients with multifocal atherosclerosis (MFA). By means of screening of 565 men at the age of 45-59 years, 64 patients with multifocal lesion of coronary, carotid and low extremity arteries were identified. The degree of stenosis had been defined both by USDS and AG. USDS provided best results compared with angiography which failed in detection of smaller grades of stenoses and abdominal aorta aneurysms. Sensitivity of duplex scanning was 90 vs. 75 % for angiography. Application of functional tests can further extend the possibilities of USDS. Thus, ultrasound assessment may be considered a useful method for detecting different characteristics of multifocal athero-sclerotic lesion and planning surgical tactics.
