Abstract：Objective To explore the imaging features and clinical significance of 64-slice spiral CT angiography (CTA) in diagnosing intracranial artery fenestration. Methods The head CTA data of 453 patients were retrospectively analyzed to obtain the information of the existence and manifestation of intracranial artery fenestration. Results 24 cases of artery fenestrations were checked out. There were 12 cases located in basilar artery, 8 cases located in anterior artery, 2 cases located in middle cerebral artery, and 2 cases located in intracranial vertebral artery. According to the size and morphology of artery fenestrations, the fenestrations were divided into fissure-pattern (18 cases) and convex-lens-pattern (6 cases). Aneurysms exsit in 8 cases among all the fenestrations. Conclusion 64-slice spiral CT which can accurately display the location, morphology and adjacent structures of fenestrations plays an important role in the diagnosis and treatment of head vasculopathy.
