Pain in the lower back is the most urgent problem of neurology. The cause of back pain can be premature aging and wear of the intervertebral discs, as well as developmental abnormalities, autoimmune reaction to the disc tissue, etc. However, vascular disorders, especially the venous system in the area of spinal nerve segments, have not been sufficiently studied. The paper considers the use of the Doppler mapping method to determine the indicators of regional blood flow in the affected areas and the possibility of using the drug L-lysine escinate in the complex treatment of lumbar dorsopathies. Doppler framing in dorsopathies can reveal a disturbance of regional blood flow in the affected areas. Complex medical treatment with the inclusion of L-lysine escinate restores regional blood flow with subsequent porlanization of peripheral blood parameters, which contributes to a more rapid regression of neurological symptoms.
