[Origin and clinical significance of the vertebral arterial fenestration: report of a case].
Fenestration of the vertebral artery, different from duplication, is a rare vascular variation, which can be usually classified into extracranial, intracranial and extracranial-intracranial types. We report a case of extracranial fenestration detected by cerebral angiography, and analyze the embryologic pathogenesis and clinical significance of this variation.
