摘要：
FIELD: medicine.SUBSTANCE: invention refers to medicine, namely neurology, and can be used for ultrasonic diagnosis of transient extravasal compression of vertebral artery (VA) in a channel of transverse processes at the level of vertebral motor segments (VMS) C0–C6. Dopplerometric of blood flow in VA in the third segment of 2 or 4 MHz pancreatic sensor of suboccipital approach in a patient's position on the back with a neutral head position is performed. That is combined with recording a time-average bloodstream linear velocity (BLV) for each VA in rest (VTAV-0). Then samples are taken: 1) three consecutive head movements to the right and to the left with neutral position of neck； 2) three consecutive head movements to the right and to the left with fixed extension of neck； 3) three consecutive head movements to the right and to the left with fixed neck bending； 4) three consecutive head-to-back movements. After each sample, both PA are insonified in the initial position and a time-averaged BLV is recorded in each VA during the second-third cardiac cycles (VTAV-1). Further, a reactivity factor Ireact for each VA for each sample: Ireact=(VTAV-1/VTAV-0-1)×100 %. If value Ireact exceeds the range of [-30 %； +30 %] and is accompanied by developing ischemia symptoms in the vertebrobasilar system – vertigo, nausea, ringing in the ears, vertebral artery syndrome is diagnosed. At that, in case Ireact exceeds the interval [-30 %； +30 %] after the head rotations in the neutral position of the neck, VA compression at the C2–C5 level. In case Ireact exceeds the interval [-30 %； +30 %] after the head turns with fixed neck extension, VA compression at S5–S6 level. In case Ireact exceeds the interval [-30 %； +30 %] after the head turns with fixed neck bending, VA compression at the C1-C2 level. In case Ireact exceeds the interval [-30 %； +30 %] after the sample with movements of the head back and forth, VA compression at the level of C0-C1.EFFECT: method provides determining the
