Introduction: We evaluated the feasibility of employing a self-expanding stent (Neuroform) in treatment of acute cerebral ischemia and compared the results of primary and secondary stenting.
Object. The object of this study was to assess outcomes in patients with arteriovenous malformations (AVMs) treated by Gamma Knife stereotactic radiosurgery (SRS); lesions were stratified by size, symptomatology, and Spetzler-Martin (S-M) grade.
BACKGROUND: The effectiveness and risk of Gamma Knife surgery (GKS) in the management of partially embolized cerebral arteriovenous malformations (AVMs) remain to be elucidated. OBJECTIVE: To evaluate the long-term imaging and clinical outcomes of GKS in AVM patients who had undergone previous partial embolization and compare the results with patients treated with GKS alone.

BACKGROUND AND PURPOSE: The PED is an FDS designed for the treatment of intracranial aneurysms. Data regarding the use of this device in acute or subacute aSAH is limited to a few case reports or small series. We aimed to demonstrate the feasibility of using an FDS, the PED, for the treatment of ruptured intracranial aneurysms with challenging morphologies.

BACKGROUND: Protection techniques using stents or microcatheters allow treatment of aneurysms with complex configurations by coil embolization. However, the application of these techniques is occasionally limited in wide-neck middle cerebral artery (MCA) aneurysms with acute angularity of the efferent branch vessel. OBJECTIVE: We describe a looping technique for passage of a microcatheter and microwire into the acutely angled efferent branch vessel without navigating the system through the aneurysm lumen.

BACKGROUND AND PURPOSE: Acute vertebrobasilar occlusion is an ominous disease with few proved effective treatments. Experience with stent retrievers is scarce and limited to combined therapies (stent retrievers associated with previous intravenous fibrinolysis, intra-arterial thrombolysis, or other mechanical devices). We present our experience with 18 patients treated with direct thrombectomy by using stent retrievers. Published online before print November 1, 2012, doi: 10.3174/ajnr.A3329 AJNR 2012 .

BACKGROUND: The Stenting and Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) study stopped recruiting patients because of higher-than-expected perioperative morbidity of primary stenting in patients with symptomatic intracranial stenosis. An alternative treatment, submaximal angioplasty without stenting, performed concurrently with SAMMPRIS, may offer revascularization benefits with a lower incidence of stenting-related risks. OBJECTIVE: To present the results of a consecutive case series of primary submaximal angioplasty procedures performed for symptomatic severe atherosclerotic intracranial stenosis refractory to medical treatment.

BACKGROUND AND PURPOSE: FDs are new intracranial stents designed to occlude aneurysms while preserving flow to jailed arterial branches. We tested this fundamental principle in a new aneurysm model.

Purpose: To report midterm results of 3 cases in which drug-eluting balloons (DEBs) were successfully used for the management of carotid in-stent restenosis (ISR).
Purpose : To evaluate the safety and efficacy of drug-eluting balloons (DEB) for the treatment of in-stent restenosis (ISR) after carotid artery stenting (CAS).
Inflammation is a significant element of the pathogenesis of cerebral aneurysm formation and progression. Key processes include macrophages infiltration, smooth muscle cell differentiation and ultimately apoptosis, as well as upregulation of cytokines, adhesion molecules, and matrix remodeling genes.1 Following intravascular injury, monocyte chemoattractant protein-1 (MCP-1) induces monocytes to leave the bloodstream. This is an elemental aspect of atherosclerosis and MCP-1 over-expression has been found in abdominal aortic aneurysms, intracranial aneurysms and subarachnoid hemorrhage.2-4 In experimental models, MCP-1 was upregulated in aneurysm walls, and MCP-1 knockout mice demonstrated decreased expression of MMPs and inhibition of aneurysmal progression.5-6.

BACKGROUND AND PURPOSE: The PS is an innovative mechanical device designed to recanalize large-vessel occlusions by thrombus aspiration. The purpose of this study was to evaluate the effectiveness and neurologic outcome of patients treated with the PS in the setting of acute ischemic stroke.

Background—Periprocedural outcome has been extensively investigated in patients undergoing carotid artery stenting. However, risk factors contributing to long-term mortality have not been comprehensively assessed. We aimed to establish a validated clinical risk score for long-term mortality in patients after carotid artery stenting.
Background and Purpose—Hemianopia can cause considerable disability. Only scarce data are available for ischemic stroke patients presenting with isolated homonymous hemianopia and being treated with intravenous thrombolysis. We analyzed outcome of such patients registered in the Safe Implementation of Thrombolysis in Stroke–International Stroke Thrombolysis Register (SITS-ISTR).
