OBJECT: The authors describe their preliminary clinical experience with the use of endovascular stents in the treatment of @entity455 of the skull base region. Because adequate distal exposure and direct surgical repair of these lesions are not often possible, conventional treatment has been deliberate @entity432 . The purpose of this report is to demonstrate the safety and efficacy as well as limitations of endovascular stent placement in the management of craniocervical @entity1317 . METHODS: Six @entity1 with @entity1317 were treated using endovascular stents. There were two @entity2548 and two @entity2849 of the distal extracranial internal carotid or vertebral arteries resulting from penetrating @entity130 , and two petrous @entity1914 associated with basal skull fractures. In one @entity1 a porous stent placement procedure was undertaken as well as coil occlusion of an @entity439 , whereas in the remaining five @entity1 covered stent grafts were used as definitive treatment. There were no procedural complications. One @entity1 in whom there was extensive traumatic arterial dissection was found to have asymptomatic stent @entity715 when angiography was repeated 1 week postoperatively. This was the only @entity1 whose associated injuries precluded routine antithrombotic or antiplatelet therapy. Follow-up examinations in the remaining five @entity1 included standard angiography (four @entity1 ) or computerized tomography angiography (one @entity1 ), which were performed 3 to 6 months postoperatively, and clinical assessments ranging from 3 months to 1 year in duration (mean 9 months). In all five cases the @entity1317 was successfully treated and the parent artery remained widely patent. No @entity1 experienced @entity439 recurrence or @entity548 , and there were no @entity1031 complications. CONCLUSIONS: The authors' experience demonstrates that endovascular treatment of @entity455 of the skull base region is both feasible and safe. The advantages of minimally invasive stent placement and parent artery preservation make this procedure for repair of @entity531 a potentially important addition to existing methods.
