KIMMERLE'S ANOMALY DURING VISUALIZATION OF THE CRANIOVERTEBRAL REGION
Abstract
Summary. Blood flow in the craniovertebral region can often be im paired, and the cause is mainly a spondylogenic factor. The consequence of such changes can be from a slight decrease in cerebral circulation to ischem ic com plications in the vascular bed. Using multislice com puted tom ography, 41 out o f 230 exam ined patients revealed the presence of various types o f K im m erle anom aly. Blood flow in the vertebral arteries in the presence of Kimmerle's anom alywas examined by transcranial Doppler ultrasonography of the vertebral arteries. Studies have show n 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.
