[Capacities of computed tomographic angiography in the diagnosis and estimation of the site, pattern, and degree of vascular bed lesion in nonspecific aortoarteritis].

ABSTRACT

Nonspecific aortoarteritis (NAA) is a chronic inflammatory disease that affects the aorta and its branches. The clinical manifestations of this disease are of a great variety and depend on the site of a lesion and the stage of the disease. A wide range of highly informative noninvasive imaging techniques, such as duplex scanning (DS), magnetic resonance imaging (MRI), and computed tomography (CT) of the aorta and its branches, are used to make a more accurate diagnosis and to determine the site and extent of a vascular bed lesion. The given clinical example suggests that CT angiography of the aorta and its branches is a high-precision technique in determining the site of vascular bed lesion in patients with NAA and the pattern and extent of arterial involvement and that it may be used for both the diagnosis of the disease at its developmental stages and the monitoring of the vessels during pathogenetic therapy.
