The method for assessing the disordered blood flow in the venous plexuses of the cervical backbone division provides for ultrasonography of the cervical arteries in the supine position of the patient with the straight position of the head. In addition, the ultrasonography of the collateral blood vessels between the vertebral veins of anterior and posterior deep and superficial plexuses of the cervical backbone division is performed with the head turned to the right or to the left, in sitting and standing positions of the patient with the straight position of the head as well as the head turned to the right or to the left, with hands up and down.
