- 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.
- Bioactive versus Bare Platinum Coils in the Treatment of Intracranial Aneurysms: The MAPS (Matrix and Platinum Science) Trial
This prospective, randomized, multicenter study compares the efficacy of the Matrix versus bare metal coils. A group of 626 patients were divided between the 2 coil types and aneurysm recurrence and hemorrhage were assessed 1 year after procedures. Recurrences were associated with initial incomplete obliterations and the bare metal coils were not inferior to Matrix coils. Thus, due to cost differences, utilization of Matrix coils may not be justified.
