Abstract

Vertebral artery fenestration is a rare vascular anomaly. It most commonly occurs in extracranial segments of the vertebral artery. This congenital anomaly can occur during the various stages of embryonic development of the vertebral artery. This usually does not have clinical significance, but the possibility of associated anomalies such as saccular aneurysms and arteriovenous malformations should be noted. Awareness of vascular anomalies is key to avoiding iatrogenic injury during endovascular diagnostic and therapeutic interventions. Here, we present incidental findings of vertebral artery fenestration in a 46-year-old woman evidenced by CT angiography of the neck's blood vessells after I .V. contrast medium applications.

Highlights

Vertebral arteries (VA) account for 30% of the blood supply to the brain, supplying predominantly the posterior parts of the brain
The Vertebral artery (VA) follow the vertical direction from C6 to the C2 level of the foramen transversarium and that are the V2 segment
Ionete and Omojola reported that failure of the regression of the second intersegmental artery leads to extracranial fenestration of the VAs [5]

Summary

INTRODUCTION

Vertebral arteries (VA) account for 30% of the blood supply to the brain, supplying predominantly the posterior parts of the brain. Studies show that about 70% of fenestrations are spotted in the upper cervical segments, with the remainder present intracranially [3]. This anomaly is often associated with other congenital intracranial and extracranial vascular anomalies, including aneurysms and arteriovenous malformations [4]. With this case report, we believe that we will raise awareness of this generally rare condition which prompts further investigation since there are some reports on higher. Bulja Deniz, et al Journal of Health Sciences 2019;9(3):177179 incidence of intracranial aneurysms and arteriovenous malformations in association with fenestrations. It has been noticed that the VAs in the level of the V4 segments are from both sides distinctly fragile and hypoplastic. (Figures 1-3)
