AMERICAN JOURNAL OF NEURORADIOLOGY. Intrasaccular Flow-Disruption Treatment of Intracranial Aneurysms: Preliminary Results of a Multicenter Clinical Study

L. Pierot, T. Liebig, V. Sychra, K. Kadziolka, F. Dorn, C. Strasilla, C. Kabbasch and J. Klisch

BACKGROUND AND PURPOSE: The endovascular treatment of intracranial aneurysms with unfavorable anatomy (large aneurysms, wide-neck) is frequently challenging and is also associated with a high incidence of significant recurrences. The WEB, an intrasaccular flow disrupter, was designed for use in this type of aneurysm. We report our early experience with this device in this multicenter study.

JOURNAL OF NEUROSURGERY. Management of tandem occlusion stroke with endovascular therapy

Haitham Dababneh, M.D, Waldo R. Guerrero, M.D, Anna Khanna, M.D, Brian L. Hoh, M.D, and J Mocco, M.D., M.S.2

Object: Approximately 25% of patients with middle cerebral artery (MCA) occlusion will have a concomitant internal carotid artery (ICA) occlusion, and 50% of patients with an ICA occlusion will have a proximal MCA occlusion. Cervical ICA occlusion with MCA embolic occlusion is associated with a low rate of recanalization and poor outcome after intravenous thrombolysis. The authors report their experience with acute ischemic stroke patients who suffered tandem ICA/MCA (TIM) occlusions and underwent intravenous thrombolysis followed by extracranial ICA angioplasty and intracranial MCA mechanical thrombectomy.

CARDIOVASCULAR DISORDERS. Correlations between prescription of anti-hypertensive medication and mortality due to stroke

Renata Papp, Albert Csaszar, Edit Paulik and Sandor Balogh

One of the most important risk factors for stroke is hypertension. A number of studies have attempted to identify the most effective anti-hypertensive therapeutic group for stroke prevention. Using an epidemiologic approach we aimed to find correlations based on Hungarian data on stroke-mortality and on prescription routine of anti-hypertensive therapeutics in three different counties, showing significant difference in stroke mortality.

AMERICAN JOURNAL OF NEURORADIOLOGY. Short- and Long-Term Hemodynamic and Clinical Effects of Carotid Artery Stenting

B. Yang, W. Chen, Y. Yang, Y. Lin, Y. Duan, J. Li, H. Wang, F. Fu, Q. Zhuge and X. Chen

BACKGROUND AND PURPOSE: Stenosis of the carotid artery may cause reduced hemodynamic and neural function that may be ameliorated with CAS. The goal of this study was to evaluate short- and long-term hemodynamic and clinical effects after CAS.

INTERNATIONAL JOURNAL OF STROKE. The association between depression, suicidal ideation, and stroke in a population-based sample

Esme Fuller-Thomson, Maressa J. Tulipano and Michael Song

Depression is a common mental health consequence of stroke. The onset of depression often begins within the first few months after a stroke (1–4). The overall frequency of poststroke depression is estimated to be 33%, with varying rates during the acute, medium-term, and long-term phases of recovery (4). In general, the frequency of depression is greater among inpatient populations than subjects living within the community (5).

BACKGROUND AND PURPOSE: Ulceration in carotid plaque is a risk indicator for ischemic stroke.

INTERNATIONAL JOURNAL OF STROKE. The management of hypertension for primary stroke prevention: a proposed approach

Mukul Sharma and Antoine M. Hakim

The prevalence of hypertension in society is high and increasing. Untreated hypertension results in stroke, dementia, and damage to major organs. This article reviews the risks that hypertension causes and the issues nowgenerally accepted as playing a role in the low level of hypertension control. These include lack of public awareness of the significance of elevated blood pressure, lack of impetus to measure blood pressure, lack of sites to perform the measurements, occasional therapeutic inertia on the part of the medical community, and poor compliance with treatment on the part of affected individuals. Innovative measures that may result in improved management of this risk factor are discussed. These include ubiquitous blood pressure measurement sites, expanding therapeutic potential by involving allied health professionals, and offering rewards for treatment and for compliance. The article also emphasises that the ideal blood pressure target for the primary prevention of stroke remains unclear.

INTERNATIONAL JOURNAL OF STROKE. Knowledge of risk factors, and warning signs of stroke: a systematic review from a gender perspective

Nanette Stroebele, Falk Muüller-Riemenschneider, Christian H. Nolte, Jacqueline Müller-Nordhorn, Angelina Bockelbrink and Stefan N. Willich

Stroke is one of the leading causes of death globally. Awareness of stroke risk factors and warning signs are important for stroke prevention and seeking care. The purpose of this systematic review was to review existing literature that assessed the knowledge of stroke risk factors and warning signs and allowed separate gender analysis. We conducted a systematic review of all published studies (to August 2008) examining knowledge of stroke risk factors and warning signs that included women and provided results separated by gender. Two reviewers selected studies for inclusion, assessed quality, and extracted data. The database search identified 2158 references for screening and 158 were selected for possible inclusion. Twenty-two studies were reviewed including 20 cross-sectional and two pretest–posttest design surveys. Overall, better stroke knowledge was observed in women compared with men in the majority of the studies although there is a general lack of knowledge in both genders. Four out of 18 studies reported better risk factor knowledge and eight out of 15 studies reported better knowledge in stroke warning signs in women compared with men. Women tended to know more evidence-based stroke risk factors than men. Stroke knowledge also appeared to be related to country of study origin, age, education, and medical history. Stroke knowledge among different populations and both in men and women is suboptimal. More research is necessary to further investigate gender differences in stroke.

STROKE. Does Impaired Cerebrovascular Reactivity Predict Stroke Risk in Asymptomatic Carotid Stenosis?

Alice King, BSc (Hons); Joaquin Serena, MD, PhD; Natan M. Bornstein, MD; Hugh S. Markus, FRCP ACES Investigators

Background and Purpose—Improved methods are required to identify the subgroup of patients with asymptomatic carotid stenosis who will have stroke develop. It has been suggested that impaired cerebral reactivity (CVR) may predict high risk, but no multicenter studies have examined this.

CVIR. Cardiovascular and Interventional Radiological Society of Europe Commentary on the Treatment of Chronic Cerebrospinal Venous Insufficiency

J. A. Reekers, M. J. Lee, A. M. Belli and F. Barkhof

Chronic cerebrospinal venous insufficiency (CCSVI) is a putative new theory that has been suggested by some to have a direct causative relation with the symptomatology associated with multiple sclerosis (MS) [1]. The core foundation of this theory is that there is abnormal venous drainage from the brain due to outflow obstruction in the draining jugular vein and/or azygos veins. This abnormal venous drainage, which is characterised by special ultrasound criteria, called the “venous hemodynamic insufficiency severity score” (VHISS), is said to cause intracerebral flow disturbance or outflow problems that lead to periventricular deposits [2].
