[New non-invasive Doppler ultrasound study of blood flow in segmental arteries].

The authors have proposed and tested a new noninvasive technique of Doppler ultrasound study of impaired blood flow in the segmental arteries, which indirectly evaluates spinal cord hemodynamics in vertebral column diseases. Clinical trials of the technique proposed have provided evidence for the association of blood flow in the segmental arteries with the degree of vertebral column canal and kyphotic deformities. A combined impact of spinal deformity and impaired blood flow in the segmental arteries at the level of lesion on the severity of neurological disorders and on deterioration of life quality in patients with spinal inflammatory diseases has been found. A relation of impaired arterial blood flow of the lower extremity to circulatory changes in the segmental arteries has been established in spinal diseases.
