Radiological anatomy of the intracranial vertebral artery in a select South African cohort of patients

Abstract The intracranial segment of the vertebral artery (VA) is the unique part of the artery where the two VAs join to form a single vascular channel, viz. the basilar artery. In addition to this typical description, anatomical variations have been described; the presence of anatomical variation...
