Новый метод оценки скорости смещения стенки брюшной аорты по данным ультразвукового исследования

Aim: To evaluate the displacement velocity wall of the abdominal aorta in healthy patients with atherosclerosis and the results of ultrasound, followed by treatment at a workstation Multivox. Materials and Methods. Ultrasound of the abdominal aorta performed 57 patients: a healthy person -15 (26.3%), patients with abdominal aortic atherosclerosis - 42 (73.7%), an aneurysm of the abdominal aorta revealed at 22 (52.4%). Results. Identified objective reduction of speed of displacement of the abdominal wall in patients with aortic atherosclerosis in comparison with a group of healthy individuals, respectively: Vs = 3.5 ± 1.1 mm/s, Vd = 1.5 ± 0.5 mm/s and Vs = 9.7 ± 1.4 mm/s . The dependence of the velocity of displacement of the abdominal aorta wall to its diameter in patients with atherosclerotic lesions of the aorta. The highest rate of displacement detected by the aneurysm diameter of 6.0 cm: Vs = 10.7 ± 2.9 mm/s , Vd = 4.8 ± 1.9 mm/s. The velocity of displacement of the wall of the aneurysm is 2.2 times higher than in intact aorta above the aneurysm. Conclusions. In patients with atherosclerotic lesions of the aortic wall displacement velocity of the abdominal aorta was significantly (p < 0.05) lower than those of healthy individuals. Development of aortic aneurysm formation accompanied a significant difference in the rate of displacement wall extended and expanded sections of the aorta, which is a negative prognostic points and leads to aggravation of pathological deformation.
