title: Traumatic basilar artery entrapment with patency of pontine perforators and absence of significant brainstem infarction: report of an unusual case.
abstract: We report a rare case of entrapment of the basilar artery into the sphenoid bone caused by a longitudinal fracture of the clivus. Using high resolution three-dimensional flat panel angiography, we show preservation of the basilar artery perforators in spite of severe stenosis of the entrapped segment of the basilar artery. There were no obvious signs and symptoms of posterior fossa stroke clinically or radiographically as far as could be assessed under given clinical circumstances.
