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

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.

[Extent and location of lesions in aorta and its main branches in patients with nonspecific aortoarteritis with various genotypes in the region of major histocompatibility complex].

Aim: To elucidate associations between location and extent of lesions of arterial vascular bed in patients with nonspecific aortoarteritis and presence of various alleles of DRB1 gene of HLA class II in patients of Russian ethnicity.

Material And Methods: Ultrasonography, magnetic resonance imaging and computed tomography were used for examination of arteries in 25 patients aged 22-69 years. Genotyping of HLA-DRB1 locus was carried out in all patients and in a group of practically healthy subjects of the same ethnic group (controls).

An examination of 40 healthy persons (80 eyes) enabled a refinement and unification of the ultrasound techniques applicable to investigations of a. ophthalmica, a. and v.

[The diagnosis of renal artery stenosis by the data from ultrasonic study methods].

The purpose of the present investigation was to elaborate diagnostic criteria for stenosing of renal arteries according to ultrasonic dopplerography. The investigation included 35 patients suffering from vasorenal hypertension with stenoses of the renal arteries documented by angiography and 63 patients with stage II essential hypertension, who made up the control group. Ultrasonic scanning of the kidneys and dopplerography of the renal arteries were performed with the use of the Acuson-128 ultrasonic system fitted out with a sector transducer operating at a frequency of 3.
