Abstract
Sulcus arteria vertebralis is the groove that is located on first cervical vertebra (atlas) where vertebral artery passes over the posterior arch of atlas to reach the foramen magnum. An abnormal bridge between the posterior part of the superior articular process and posterolateral part of the posterior arch of the atlas is a common variation detected by radiographies of the patients. This bony bridge is called as ponticulus posticus or a variant of Kimmerle’s anomaly. Its prevalance has been reported to be between 5.14-37.83%. This common variation may be a possible cause of the ischemia in posterior circulation and headache. This study aimed to determine and analyse the existence of ponticulus posticus and correlate the dimensions of the vertebral artery with its prevalance with a retrospective analysis of 600 CT angiographies (1mm sections) of Department of Radiology, University Hospital of Hacettepe. We have detected a complete ponticulus posticus in 12.10% of the patients and 27.38% of them were bilateral. Right and left sided postsulcus arterial dimensions were found to be lesser then the pre-sulcus dimensions with the incomplet ponticulus posticus existence. Variations of the sulcus arterial vertebralis is a commonly studied variation among different nations. This study will be a preliminary analysis for the clinical problems like headache, vascular diseases and surgical interventions of atlas.
