Fenestration of the vertebral artery presented by computed tomography angiography of the neck’s blood vessels: A case study
Vertebral artery (VA) fenestration is a rare vascular anomaly. It most commonly occurs in extracranial segments of the VA. This congenital anomaly can occur during the various stages of embryonic development of the VA. 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 a key to avoid iatrogenic injury during endovascular diagnostic and therapeutic interventions. Here, we present incidental findings of VA fenestration in a 46-year-old woman evidenced by computed tomography angiography of the neck’s blood vessels after I.V. contrast medium applications.
