AMERICAN JOURNAL OF NEURORADIOLOGY. Combined Low-Dose Contrast-Enhanced MR Angiography and Perfusion for Acute Ischemic Stroke at 3T: A More Efficient Stroke Protocol

K. Nael, A. Meshksar, B. Ellingson, M. Pirastehfar, N. Salamon, P. Finn, D.S. Liebeskind and J.P. Villablanca

Background and Purpose: There is need to improve image acquisition speed for MR imaging in evaluation of patients with acute ischemic stroke. The purpose of this study was to evaluate the feasibility of a 3T MR stroke protocol that combines low-dose contrast-enhanced MRA and dynamic susceptibility contrast perfusion, without additional contrast.

AMERICAN JOURNAL OF NEURORADIOLOGY. Inter- and Intraobserver Agreement in Scoring Angiographic Results of Intra-Arterial Stroke Therapy

M. Gaha, C. Roy, L. Estrade, G. Gevry, A. Weill, D. Roy, M. Chagnon and J. Raymond

Background and Purpose: Angiographic results are commonly used as surrogate markers of the success of intra-arterial therapies for acute stroke. Inter- and intraobserver agreement in judging angiographic results remain poorly characterized. Our goal was to assess 2 commonly used revascularization scales.

AMERICAN JOURNAL OF NEURORADIOLOGY. Phlebographic Study Does Not Show Differences Between Patients with MS and Control Subjects

M. Stefanini, S. Fabiano, F. Garaci, S. Marziali, A. Meschina, V. Cama, M. Fornari, S. Rossi, D. Centonze, R. Gandini, G. Simonetti and R. Floris

Background and Purpose: Hypothetical correlation between chronic cerebrospinal venous insufficiency and MS has gained the attention of patients and the scientific community. Studies performed by echo-color Doppler ultrasonography have shown different results, and it is necessary to use more objective diagnostic techniques. The aim of our study was to evaluate the presence of stenoses affecting azygos veins and internal jugular veins by use of venography in patients with MS.

SPRINGER. Complications of mechanical thrombectomy for acute ischemic stroke—a retrospective single-center study of 176 consecutive cases

Daniel Behme, Ludger Gondecki, Sarah Fiethen, Annika Kowoll, Anastasios Mpotsaris, Werner Weber

Introduction: There is only very limited data about complications in mechanical thrombectomy for acute ischemic stroke. The purpose of this study was to evaluate the frequency and the clinical relevance of procedure-related complications in mechanical thrombectomy.

JOURNAL OF NEUROSURGERY. Neuro-ophthalmic effects of stenting across the ophthalmic artery origin in the treatment of intracranial aneurysms Clinical article

Robert S. Heller, M.D.1, Claire M. Lawlor, M.D.2, Thomas R. Hedges III, M.D.2, Yanik J. Bababekov, M.D., M.P.H.2, Mina G. Safain, M.D.1, and Adel M. Malek, M.D., Ph.D.1

Object: The benefits of treating intracranial aneurysms in the region of the anterior visual pathways are well understood. However, the adverse effects of endovascular stenting across the ophthalmic artery have received little attention. The authors reviewed their experience with patients who had stents deployed across the ophthalmic artery origin.

JOURNAL OF NEUROSURGERY. Hemorrhage risks and functional outcomes of untreated brainstem cavernous malformations

Da Li, M.D., Shu-Yu Hao, M.D., Ph.D., Gui-Jun Jia, M.D., Ph.D., Zhen Wu, M.D., Li-Wei Zhang, M.D., Ph.D., and Jun-Ting Zhang, M.D.

Object: Cerebral cavernous malformations have been studied widely, but the natural history of brainstem cavernous malformations (CMs) is not well defined, and hemorrhages caused by brainstem CMs are devastating. The goal of this study was to quantify the hemorrhage risks and functional outcomes of patients with brainstem CMs.

THE LANCET NEUROLOGY. Simvastatin in aneurysmal subarachnoid haemorrhage (STASH): a multicentre randomised phase 3 trial

Peter J Kirkpatrick FMedSci a, Carole L Turner MSc, Christopher Smith PhD a, Prof Peter J Hutchinson FRCS a, Prof Gordon D Murray PhD b, for the STASH Collaborators

Background: The benefit of statins in patients with acute aneurysmal subarachnoid haemorrhage is unclear. We aimed to determine whether simvastatin 40 mg could improve the long-term outcome in patients with this disorder.

THE LANCET NEUROLOGY. Time to angiographic reperfusion and clinical outcome after acute ischaemic stroke: an analysis of data from the Interventional Management of Stroke (IMS III) phase 3 trial

Prof Pooja Khatri MD, Sharon D Yeatts PhD b, Mikael Mazighi MD c, Prof Joseph P Broderick MD a, Prof David S Liebeskind MD d, Prof Andrew M Demchuk MD e, Prof Pierre Amarenco MD c, Janice Carrozzella MSN a, Judith Spilker BSN a, Lydia D Foster PhD b, Prof Mayank Goyal MD e, Prof Michael D Hill MD e, Prof Yuko Y Palesch PhD b, Prof Edward C Jauch MD b, Prof E Clarke Haley MD f, Achala Vagal MD a, Prof Thomas A Tomsick MD a, for the IMS III Trialists

Background: The IMS III trial did not show a clinical benefit of endovascular treatment compared with intravenous alteplase (recombinant tissue plasminogen activator) alone for moderate or severe ischaemic strokes. Late reperfusion of tissue that was no longer salvageable could be one explanation, as suggested by previous exploratory studies that showed an association between time to reperfusion and good clinical outcome. We sought to validate this association in a preplanned analysis of data from the IMS III trial.

AMERICAN JOURNAL OF NEURORADIOLOGY. Radiation Doses of Cerebral Blood Volume Measurements Using C-Arm CT: A Phantom Study

W.F. Chu, C.J. Lin, W.S. Chen, S.C. Hung, C.F. Chiu, T.H. Wu and W.Y. Guo

Background and Purpose: Parenchymal blood volume measurement by C-arm CT facilitates in-room peritherapeutic perfusion evaluation. However, the radiation dose remains a major concern. This study aimed to compare the radiation dose of parenchymal blood volume measurement using C-arm CT with that of conventional CTP using multidetector CT.

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. The SYNTAX score does not predict presence of carotid disease in a multivessel coronary disease population

Luca Costanzo MD*, Maria Barbara Campisano MD, Davide Capodanno MD, PhD, Andrea Sole MD, Carmelo Grasso MD, Mario Ragusa MD, Giuseppe Ronsivalle MD, Claudia Tamburino MD, Corrado Tamburino MD, PhD andLuigi Di Pino MD, PhD

Background: Numerous reports have shown the relationship between carotid artery atherosclerosis and coronary artery disease (CAD). However, the association between complex CAD evaluated by SYNTAX score (SxScore) and prevalence of carotid lesion (CL) has not been fully investigated. We sought to assess the prevalence of carotid atherosclerosis in patients with multivessel CAD assessed by SxScore and the relationship between SxScore severity and features of carotid atherosclerosis.

JOURNAL OF NEUROSURGERY. Early experience with stent retrievers and comparison with previous-generation mechanical thrombectomy devices for acute ischemic stroke

Eric M. Deshaies, M.D.1, Amit Singla, M.B.B.S.1, Mark R. Villwock, M.S.1, David J. Padalino, M.D.1, Sameer Sharma, M.B.B.S.2, and Amar Swarnkar, M.B.B.S.3

Object: There is limited information regarding patient outcomes following interventions for stroke during the window for endovascular therapy. Studies have suggested that recently approved stent retrievers are safer and more effective than earlier-generation thrombectomy devices. The authors compared cases in which the Solitaire-FR device was used to those in which a MERCI or Penumbra device was used.
