THE LANCET. Aggressive medical treatment with or without stenting in high-risk patients with intracranial artery stenosis (SAMMPRIS): the final results of a randomised trial

Background: Early results of the Stenting and Aggressive Medical Management for Preventing Recurrent stroke in Intracranial Stenosis trial showed that, by 30 days, 33 (14·7%) of 224 patients in the stenting group and 13 (5·8%) of 227 patients in the medical group had died or had a stroke (percentages are product limit estimates), but provided insufficient data to establish whether stenting offered any longer-term benefit. Here we report the long-term outcome of patients in this trial.

EUROPEAN JOURNAL OF RADIOLOGY. Angioarchitectural characteristics associated with initial hemorrhagic presentation in supratentorial brain arteriovenous malformations

Jianwei Pan , Lei Feng , Fernando Vinuela , Hongwei He , Zhongxue Wus , Renya Zhan

Objective: The difference in arterial supply, venous drainage, functional localization in supratentorial and infratentorial compartments may contribute to the conflicting results about risk factors for hemorrhage in published case series of brain arteriovenous malformation (bAVM). Further investigation focused on an individual brain compartment is thus necessary. This retrospective study aims to identify angioarchitectural characteristics associated with the initial hemorrhagic event of supratentorial bAVMs.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. United Kingdom Carotid Artery Stent Registry: Short- and Long-Term Outcomes

S. D. Goode, T. J. Cleveland, P. A. Gaines

Background: Carotid artery stenting (CAS) has evolved to treat carotid artery disease with the intention of prevent stroke. The British Society of Interventional Radiologists developed a voluntary registry to monitor the practice of this novel procedure. We present the data from the United Kingdom (UK) CAS registry for short and long-term outcomes for symptomatic and asymptomatic carotid disease.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Neurointerventional Treatment in Acute Stroke. Whom to Treat? (Endovascular Treatment for Acute Stroke: Utility of THRIVE Score and HIAT Score for Patient Selection)

Lars Fjetland, Sumit Roy, Kathinka D. Kurz, Tore Solbakken, Jan Petter Larsen, Martin W. Kurz

Purpose: Intra-arterial therapy (IAT) is used increasingly as a treatment option for acute stroke caused by central large vessel occlusions. Despite high rates of recanalization, the clinical outcome is highly variable. The authors evaluated the Houston IAT (HIAT) and the totaled health risks in vascular events (THRIVE) score, two predicting scores designed to identify patients likely to benefit from IAT.

STROKE. Clinical Sciences. THRIVE Score Predicts Outcomes With a Third-Generation Endovascular Stroke Treatment Device in the TREVO-2 Trial

Alexander C. Flint, MD, PhD; Bin Xiang, PhD; Rishi Gupta, MD; Raul G. Nogueira, MD; Helmi L. Lutsep, MD; Tudor G. Jovin, MD; Gregory W. Albers, MD; David S. Liebeskind, MD; Nerses Sanossian, MD; Wade S. Smith, MD, PhD for the TREVO-2 Trialists

Background and Purpose: Several outcome prediction scores have been tested in patients receiving acute stroke treatment with previous generations of endovascular stroke treatment devices. The TREVO-2 trial was a randomized controlled trial comparing a novel endovascular stroke treatment device (the Trevo device) to a previous-generation endovascular stroke treatment device (the Merci device).

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Incidence and Clinical Impact of Stroke Complicating Percutaneous Coronary Intervention. Results of the Euro Heart Survey Percutaneous Coronary Interventions Registry

Nicolas Werner, MD, Timm Bauer, MD, Matthias Hochadel, PhD, Ralf Zahn, MD, Franz Weidinger, MD, Jean Marco, MD, Christian Hamm, MD, Anselm K. Gitt, MD and Uwe Zeymer, MD

Background—Stroke is a rare but serious complication of percutaneous coronary interventions (PCIs). So far, scant information is available about the incidence and outcome of patients developing stroke after PCI for stable angina or acute coronary syndrome (ACS) in daily clinical practice in Europe today.

AMERICAN JOURNAL OF NEURORADIOLOGY. Coil Embolization versus Clipping for Ruptured Intracranial Aneurysms: A Meta-Analysis of Prospective Controlled Published Studies

G. Lanzinoa, M.H. Muradb, P.I. d Ursod and A.A. Rabinsteinc

BACKGROUND AND PURPOSE: Coil embolization is an alternative to clipping for intracranial aneurysms. However, controversy exists regarding the best therapeutic strategy in patients with ruptured aneurysms, and there is great center- and country-related variability in the rates of clipping versus coiling. We performed a meta-analysis of prospective controlled trials of clipping versus coil embolization for ruptured aneurysms.
