Kimmerle's anomaly during visualization of the craniovertebral region
Blood flow in the craniovertebral region can often be impaired, and the cause is mainly a spondylogenic factor. The consequence of such changes can be from a slight decrease in cerebral circulation to ischemic complications in the vascular bed. Using multislice computed tomography, 41 out of 230 examined patients revealed the presence of various types of Kimmerle anomaly. Blood flow in the vertebral arteries in the presence of Kimmerle's anomaly was examined by transcranial Doppler ultrasonography of the vertebral arteries. Studies have shown that Kimmerle's anomaly can occur in all age groups. The detection rate of Kimmerle's anomaly was within 17.8% of cases. Most often, bilateral Kimmerle's anomaly and its complete (closed) variant were detected, which, according to transcranial Doppler sonography, affects the blood flow.
