NEURORADIOLOGY. Developmental venous anomalies: appearance on whole-brain CT digital subtraction angiography and CT perfusion

Eric H. Hanson, Cayce J. Roach, Erik N. Ringdahl, Brad L. Wynn, Sean M. DeChancie, Nathan D. Mann, Alan S. Diamond and William W. Orrison

Introduction: Developmental venous anomalies (DVA) consist of dilated intramedullary veins that converge into a large collecting vein. The appearance of these anomalies was evaluated on whole-brain computed tomography (CT) digital subtraction angiography (DSA) and CT perfusion (CTP) studies.

CIRCULATION. Clinical Referral Patterns for Carotid Artery Stenting Versus Carotid Endarterectomy: Results From the Carotid Artery Revascularization and Endarterectomy Registry

Ryan B. Longmore, Robert W. Yeh, Kevin F. Kennedy, H. Vernon Anderson, Christopher J. White, Lance S. Longmore, Kenneth Rosenfield, Kalon K. L. Ho and John A. Spertus

Clazosentan, an endothelin receptor antagonist, has been shown to reduce vasospasm after aneurysmal subarachnoid hemorrhage (aSAH). CONSCIOUS-3 assessed whether clazosentan reduced vasospasmrelated morbidity and all-cause mortality postaSAH secured by endovascular coiling. Copyright © 2011 American Heart Association.

NEURORADIOLOGY. Postprocedural CT for perivertebral cement leakage in percutaneous vertebroplasty is not necessary—results from VERTOS II

Alexander Venmans, Caroline A. Klazen, Willem Jan van Rooij, Jolanda de Vries, Willem P. Mali and Paul N. Lohle

Introduction During percutaneous vertebroplasty (PV), perivertebral cement leakage frequently occurs. There is some concern that cement deposits may migrate towards the lungs via the veins during follow-up. We used baseline and follow-up computed tomography (CT) to assess the incidence and extend of late cement migration in a large consecutive patient cohort. Neuroradiology (2011) 53:19–22.

NEURORADIOLOGY. Comparing different MR angiography strategies of carotid stents in a vascular flow model: toward stent-specific recommendations in MR follow-up

Andreas M. J. Frölich, Sara M. Pilgram-Pastor, Marios N. Psychogios, Alexander Mohr and Michael Knauth

Introduction: Carotid artery stenting (CAS) requires adequate follow-up imaging to assess complications such as in-stent stenosis or occlusion. Options include digital subtraction angiography, CT angiography, ultrasound, and MR angiography (MRA), which may offer a non-invasive option for CAS follow-up imaging. The aim of this study was to assess contrast-enhanced MRA (CE-MRA) and three-dimensional time-of-flight MRA (3D-TOF) for visualization of the in-stent lumen in different carotid stents.

AMERICAN JOURNAL OF NEURORADIOLOGY. Transverse Sinus Stenting for Idiopathic Intracranial Hypertension: A Review of 52 Patients and of Model Predictions

R.M. Ahmed, M. Wilkinson, G.D. Parker, M.J. Thurtell, J. Macdonald, P.J. McCluskey, R. Allan, V. Dunne, M. Hanlon, B.K. Owlere and G.M. Halmagyi

BACKGROUND AND PURPOSE: Transverse sinus stenosis is common in patients with IIH. While the role of transverse sinus stenosis in IIH pathogenesis remains controversial, modeling studies suggest that stent placement within a transverse sinus stenosis with a significant pressure gradient should decrease cerebral venous pressure, improve CSF resorption in the venous system, and thereby reduce intracranial (CSF) pressure, improving the symptoms of IIH and reducing papilledema. We aimed to determine if IIH could be reliably treated by stent placement in transverse sinus stenosis.

JOURNAL OF NEURORADIOLOGY. Flow diverter stents in the treatment of intracranial aneurysms: Where are we?

Laurent Pierot

Flow diverter stents are devices designed to treat complex aneurysms. According to preliminary series published in the literature, treatment of aneurysms with flow diverters is highly efficacious with acceptable morbidity and mortality. Delayed aneurysm ruptures have been reported but mechanisms are actually not completely elucidated. In-stent thrombosis or stenosis was also observed. Indications of flow diverters are complex aneurysms (fusiform, large and giant, wide neck, small aneurysms untreatable by conventional coiling) as well as recurrences. Several randomized studies and registries are actually in progress and will contribute to a more precise knowledge of the place of the flow diverters in the treatment of intracranial aneurysms. © 2011 Elsevier Masson SAS.

STROKE. Aspirin as a Promising Agent for Decreasing Incidence of Cerebral Aneurysm Rupture

David M. Hasan, MD; Kelly B. Mahaney, MD; Robert D. Brown Jr, MD, MPH; Irene Meissner, MD; David G. Piepgras, MD; John Huston, MD; Ana W. Capuano, MPS, MS; James C. Torner, PhD; for the International Study of Unruptured Intracranial Aneurysms Investigators

Background and Purpose—Chronic inflammation is postulated as an important phenomenon in intracranial aneurysm wall pathophysiology. This study was conducted to determine if aspirin use impacts the occurrence of intracranial aneurysm rupture. Stroke. 2011; 42: 3156-3162 Published online before print October 6, 2011, doi: 10.1161/​STROKEAHA.111.619411. Copyright © 2011 American Heart Association, Inc. All rights reserved.
