AMERICAN JOURNAL OF NEURORADIOLOGY. Double Stent–Assisted Coil Embolization Treatment for Bifurcation Aneurysms: Immediate Treatment Results and Long-Term Angiographic Outcome

K. Yavuza, S. Geyika, S. Cekirgea and I. Saatcia

BACKGROUND AND PURPOSE: The goal of endovascular treatment of cerebral bifurcation aneurysms is to achieve safe coiling of the sac along with preserving patency of the diverging branches. Our purpose was evaluate procedural safety and efficacy as well as the long-term durability of endovascular treatment of bifurcation aneurysms with double stent–assisted coiling.

THE NEW ENGLAND JOURNAL OF MEDICINE. Clopidogrel with Aspirin in Acute Minor Stroke or Transient Ischemic Attack

Yongjun Wang, M.D., Yilong Wang, M.D., Ph.D., Xingquan Zhao, M.D., Ph.D., Liping Liu, M.D., Ph.D., David Wang, D.O., F.A.H.A., F.A.A.N., Chunxue Wang, M.D., Ph.D., Chen Wang, M.D., Hao Li, Ph.D., Xia Meng, M.D., Ph.D., Liying Cui, M.D., Ph.D., Jianping Jia, M.D., Ph.D., Qiang Dong, M.D., Ph.D., Anding Xu, M.D., Ph.D., Jinsheng Zeng, M.D., Ph.D., Yansheng Li, M.D., Ph.D., Zhimin Wang, M.D., Haiqin Xia, M.D., and S. Claiborne Johnston, M.D., Ph.D. for the CHANCE Investigators N Engl J Med 2013; 369:11-19July 4, 2013DOI: 10.1056/NEJMoa1215340

Background: Stroke is common during the first few weeks after a transient ischemic attack (TIA) or minor ischemic stroke. Combination therapy with clopidogrel and aspirin may provide greater protection against subsequent stroke than aspirin alone.

AMERICAN JOURNAL OF NEURORADIOLOGY. Coil Type Does Not Affect Angiographic Follow-Up Outcomes of Cerebral Aneurysm Coiling: A Systematic Review and Meta-Analysis

I. Rezeka, G. Mousand, Z. Wangb, M.H. Muradb and D.F. Kallmesa,c

BACKGROUND AND PURPOSE: Previous studies varied in their conclusions about the superiority of second-generation coils compared with bare platinum. In this systematic review and meta-analysis, we assessed differences in reported unfavorable angiographic outcomes of cerebral aneurysms treated with coil embolization as a function of coil type.

NEUROSURGERY. Neuroform Intracranial Stenting for Aneurysms Using Simple and Multi-stent Technique Is Associated With Low Risk of Magnetic Resonance Diffusion-Weighted Imaging Lesions

Heller, Robert S. MD; Dandamudi, Venkata MD; Calnan, Daniel PhD; Malek, Adel M. MD, PhD

BACKGROUND: Detection of procedural thromboembolism by diffusion-weighted magnetic resonance imaging (MR-DWI+) can help identify and mitigate endovascular risk factors. Data remain scant on procedural MR-DWI+ following the use of the Neuroform open-cell design stent in aneurysm embolization.

NEUROSURGERY. Early vs Delayed Cerebral Infarction After Aneurysm Repair After Subarachnoid Hemorrhage

Kumar, Abhay MD†; Brown, Robert MD†; Dhar, Rajat MD†; Sampson, Tomoko MD†; Derdeyn, Colin P. MD‡; Moran, Christopher J. MD‡; Diringer, Michael N. MD†,§

BACKGROUND: Cerebral infarction is a major contributor to poor outcome after subarachnoid hemorrhage (SAH). Although usually considered a complication of delayed cerebral ischemia, infarcts may also occur early, in relation to initial brain injury or aneurysm-securing procedures.

AMERICAN JOURNAL OF NEURORADIOLOGY. Endovascular Treatment of Deep Hemorrhagic Brain Arteriovenous Malformations with Transvenous Onyx Embolization

A. Consolia, L. Renieria, S. Nappinia, N. Limbuccia and S. Mangiaficoa

SUMMARY: Brain AVMs are a rare cause of cerebral hemorrhage and SAH, and their treatment is still debated. The aim of this study was to describe a novel endovascular approach with transvenous embolization of deep hemorrhagic brain AVMs. Five patients (3 females, 2 males; mean age, 33.2 years) underwent a transvenous embolization of a deep hemorrhagic brain AVM at our institution between February and April 2012. Clinical and angiographic data at the end of the procedure and after 6 months are reported. All the AVMs were completely obliterated, and no intra- or postprocedural complications occurred. The clinical outcome was unchanged or improved in all patients. Transvenous endovascular treatment may be considered in small, hemorrhagic, and deep AVMs with single deep drainage in those cases in which neurosurgical and radiosurgical treatment might not be indicated.

THE LANCET NEUROLOGY. Restenosis after carotid artery stenting and endarterectomy: a secondary analysis of CREST, a randomised controlled trial

The CREST Investigators

Background: In the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST), the composite primary endpoint of stroke, myocardial infarction, or death during the periprocedural period or ipsilateral stroke thereafter did not differ between carotid artery stenting and carotid endarterectomy for symptomatic or asymptomatic carotid stenosis. A secondary aim of this randomised trial was to compare the composite endpoint of restenosis or occlusion.

AMERICAN JOURNAL OF NEURORADIOLOGY. Endovascular Management of Distal ACA Aneurysms: Single-Institution Clinical Experience in 22 Consecutive Patients and Literature Review

D.D. Cavalcantia, A.A. Ablaa, N.L. Martirosyana, C.G. McDougalla, R.F. Spetzlera and F.C. Albuquerquea

BACKGROUND AND PURPOSE: Distal ACA aneurysms remain difficult to treat with endovascular therapy, but improved technology and experience allows for the treatment of some of these aneurysms with excellent results. The purpose of this study was to assess the status of endovascular treatment of distal ACA aneurysms by comparing our results with recent endovascular and microsurgical series of distal ACA aneurysms.

AMERICAN JOURNAL OF ROENTGENOLOGY. Effects of Low-Dose Protocols in Endovascular Treatment of Intracranial Aneurysms: Development of Workflow Task Analysis During Cerebral Endovascular Procedures

Jean Christophe Gentric, Pierre Jannin, Brivael Trelhu, Laurent Riffaud, Hélène Raoult, Jean Christophe Ferré and Jean Yves Gauvrit

OBJECTIVE. Reducing radiation exposure through the use of low-dose protocols during cerebral endovascular procedures is recommended, but evaluation of the impact on the procedure itself is difficult and subjective. A workflow task analysis could provide an objective comparison of two different radiation exposure protocols.

AMERICAN JOURNAL OF NEURORADIOLOGY. Frequency and Relevance of Anterior Cerebral Artery Embolism Caused by Mechanical Thrombectomy of Middle Cerebral Artery Occlusion

W. Kurrea, K. Vorlaendera, M. Aguilar-Péreza, E. Schmidb, H. Bäznera and H. Henkesb

BACKGROUND AND PURPOSE: Spread of thrombus material in previously unaffected vessels is a potential hazard of mechanical thrombectomy, but it has not yet been investigated in detail, to our knowledge. Our purpose was to evaluate the frequency and relevance of these events in mTE of M1 occlusions.
