STROKE. Relative Survival After Transient Ischaemic Attack. Results From the Program of Research Informing Stroke Management (PRISM) Study

Background and Purpose—There is a lack of modern-day data quantifying the effect of transient ischemic attack (TIA) on survival, and recent data do not take into account expected survival.

NEUROSURGERY. Feasibility, Safety, and Periprocedural Complications Associated With Endovascular Treatment of Selected Ruptured Aneurysms Under Conscious Sedation and Local Anesthesia

BACKGROUND: Endovascular coil embolization of ruptured aneurysms is performed under general anesthesia at most centers for perceived improved image quality and patient safety.

STROKE. Mechanical Thrombolysis and Stenting in Acute Ischemic Stroke

Acute ischemic stroke is one of the major sources of morbidity and mortality in the industrialized countries. The lifetime risk of stroke is estimated to be 1 in 5 for middle-aged women and 1 in 6 for men according to the Framingham Study.1 Outcome depends on the length of time between onset of symptoms and revascularization, the recanalization rate, and on whether or not intracranial hemorrhage occurs.2 A meta-analysis of 52 studies on thrombolysis outcome in 2066 patients showed that the chance of an independent life after stroke increases 4.4 times for patients with successful recanalization compared with patients without recanalization; mortality rate decreases 4-fold.2

AMERICAN JOURNAL OF NEURORADIOLOGY. Evaluating CT Perfusion Using Outcome Measures of Delayed Cerebral Ischemia in Aneurysmal Subarachnoid Hemorrhage

BACKGROUND AND PURPOSE: DCI is a serious complication following aneurysmal SAH and remains a leading cause of morbidity and mortality. Our aim was to evaluate CTP in aneurysmal SAH by using outcome measures of DCI.

STROKE. Advances in Stroke. Critical Care and Emergency Medicine

The science of neurocritical care and emergency medicine has advanced in several areas over the last year, particularly in the management of acute hypertension during neurological emergencies.

NEUROSURGERY. Cerebral Aneurysms in Pregnancy and Delivery: Pregnancy and Delivery Do Not Increase the Risk of Aneurysm Rupture

BACKGROUND: It is not known what effect pregnancy or delivery has on the risk of rupture of an intracranial aneurysm, and, consequently, the optimal management of unruptured aneurysms in pregnancy is unclear.

STROKE. Systemic Thrombolysis in Patients With Acute Ischemic Stroke and Internal Carotid ARtery Occlusion. The ICARO Study

Background and Purpose—The beneficial effect of intravenous thrombolytic therapy in patients with acute ischemic stroke attributable to internal carotid artery (ICA) occlusion remains unclear. The aim of this study was to evaluate the efficacy and safety of intravenous recombinant tissue-type plasminogen activator in these patients.

EUROPEAN JOURNAL OF VASCULAR AND ENDOVASCULAR SURGERY. Current Status of Clinical Magnetic Resonance Imaging for Plaque Characterisation in Patients with Carotid Artery Stenosis

Objective: The article aims to provide an overview of the literature that assessed the agreement between magnetic resonance imaging (MRI) and histology for specific carotid plaque characteristics associated with vulnerability in terms of sensitivity and specificity.

AMERICAN JOURNAL OF NEURORADIOLOGY. Microcatheter to Recanalization (Procedure Time) Predicts Outcomes in Endovascular Treatment in Patients with Acute Ischemic Stroke: When Do We Stop?

BACKGROUND AND PURPOSE: Endovascular treatment for acute ischemic stroke consists of various mechanical and pharmacologic modalities used for recanalization of arterial occlusions. We performed this study to determine the relationship among procedure time, recanalization, and clinical outcomes in patients with acute ischemic stroke undergoing endovascular treatment.

STROKE. Advances in Stroke. Advances in Interventional Neuroradiology

NEUROSURGERY. Results of Stent-Assisted vs Non-Stent-Assisted Endovascular Therapies in 489 Cerebral Aneurysms: Single-Center Experience

BACKGROUND: Whether the addition of stenting to intracranial aneurysm coil embolization results in benefit in terms of occlusion rates or additional risk in terms of periprocedural adverse events is not clear.

AMERICAN JOURNAL OF NEURORADIOLOGY. Middle Cranial Fossa Sphenoidal Region Dural Arteriovenous Fistulas: Anatomic and Treatment Considerations

BACKGROUND AND PURPOSE: DAVFs rarely involve the sphenoid wings and middle cranial fossa. We characterize the angiographic findings, treatment, and outcome of DAVFs within the sphenoid wings.

ANNALS OF VASCULAR SURGERY. The Effect of Statin Use on Embolic Potential During Carotid Angioplasty and Stenting

Background: Statin use results in atherosclerotic plaque stabilization. We sought to determine the effects of statins on the size and number of embolic particles generated during carotid artery stenting (CAS).

AMERICAN JOURNAL OF NEURORADIOLOGY. Effect of Bifurcation Angle Configuration and Ratio of Daughter Diameters on Hemodynamics of Bifurcation Aneurysms

BACKGROUND AND PURPOSE: EL associated with ruptured aneurysms is higher than that for unruptured aneurysms. In this study, the effect of arterial morphologic variation of bifurcation aneurysms on EL was investigated in idealized models of middle cerebral artery aneurysms.

STROKE. The Safety of Intravenous Thrombolysis for Ischemic Stroke in Patients With Pre-Existing Cerebral Aneurysms. A Case Series and Review of the Literature

Background and Purpose—Unruptured cerebral aneurysms are currently considered a contraindication to intravenous tissue-type plasminogen activator for acute ischemic stroke. This is due to a theoretical increase in the risk of hemorrhage from aneurysm rupture, although it is unknown whether this risk is a significant one. We sought to determine the safety of intravenous tissue-type plasminogen activator administration in a cohort of patients with pre-existing aneurysms.
