NCT04562259

Brief Summary

Kimmerle's anomaly is a bony bridge over the posterior arch of the first cervical vertebra that forms a bony ring. The vertebral artery passes through the opening. This bone bridge could theoretically be an extravasal compression of the artery and disrupt the normal blood flow to the brain. Evaluating the data of X-ray methods, determine the frequency of occurrence and types of Kimmerle anomaly.

Outcome Measures

Primary Outcomes (1)

  • In patients with Kimmerle anomaly, determine the types of forms of this pathology

    In patients with Kimmerle's anomaly, using computed tomography of the brain with the capture of the upper cervical spine and cervical spine, it is planned to determine at what age this pathology is more common, localization of the anomaly (right, left), complete or incomplete form of the anomaly.

    up to 36 months

Study Arms (1)

patients with Kimmerle's anomaly

patients who have a complete or incomplete bony bridge over the posterior arch of the first cervical vertebra

Radiation: Verification of Kimmerle's anomaly by x-ray methods of research

Interventions

In patients with Kimmerle's anomaly, using computed tomography of the brain with the capture of the upper cervical spine and cervical spine, it is planned to determine at what age this pathology is more common, localization of the anomaly (right, left), complete or incomplete form of the anomaly.
