Entrapment of the basilar artery within a clivus fracture: Case report and literature review.

A review of the literature revealed that basilar artery (BA) entrapment is a very rare (17 cases published) and severe pathological condition, which often leads to death. We report the case of a 72-year-old man who presented with a longitudinal clivus fracture associated with a basilar artery entrapment. This entrapment was responsible for a basilar artery dissection, which led to an ischemic stroke in the pons. The patient was managed with medical treatment, mainly to avoid a progression towards an ischemic stroke. It consisted of heparin therapy followed by antiplatelet therapy, which finally resulted in a successful outcome. In BA entrapment most of the patients who had a favorable outcome received antithrombotic therapy. This suggests that antithrombotic therapy might be useful in the first line treatment of post-traumatic BA entrapment.
