- Influence of Patient Age on Angioarchitecture of Brain Arteriovenous Malformations
Over 800 AVMs were retrospectively reviewed to determine if clinical and angioarchitectural features varied between children and adults. The authors found that hemorrhages and exclusively deep venous drainage were more common in children but high-risk features such as venous ectasia and feeding artery aneurysm were more common in adults. Thus, these latter high-risk features may take time to develop.
- Use of Flow-Diverting Devices in Fusiform Vertebrobasilar Giant Aneurysms: A Report on Periprocedural Course and Long-Term Follow-Up
This article presents the authors' experience and long-term follow-up of 6 patients with fusiform and giant aneurysms of the vertebrobasilar system treated with flow-diverting devices. Devices were deployed uneventfully with no periprocedural complications. One year later, 3 patients had recurrent cerebral infarctions and 2 had acute thrombotic in-stent occlusions. Four patients died during the follow-up period. The authors do not intend to treat any more patients in this fashion until they have a better understanding of flow-diverting devices in this setting.
