OBJECTIVE: To demonstrate that nidus embolization of brain arteriovenous malformations(AVMs) with Histoacryl (B. Braun, Melsungen, Germany) is effective and yields low morbidity mortality rates. METHODS: We present a retrospective analysis 54 AVMs treated at the University Illinois Chicago from April 1994 to December 1995. Treatment modalities included in all cases then surgical resection or radiosurgery. INSTRUMENTATION: The was reached combined use Magic microcatheter(Balt, Montmorency,...
Atherosclerotic vertebrobasilar (VB) occlusive disease is a significant etiology of posterior circulation stroke, with regional hypoperfusion as an important potential contributor to stroke risk.To test the hypothesis that, among patients symptomatic VB stenosis or occlusion, those distal blood flow compromise measured by large-vessel quantitative magnetic resonance angiography (QMRA) are at higher risk subsequent stroke.A prospective, blinded, longitudinal cohort study was conducted 5...
Object. Reports in the literature have offered discussions of feasibility, efficacy, and safety balloon-assisted Guglielmi detachable coil (GDC) placement wide-necked intracranial aneurysms, which was first described by Jacques Moret as “remodeling technique.” In this article authors summarize their results a subset aneurysms treated with GDCs using remodeling technique. Methods. This report contains retrospective analysis 72 patients 75 who underwent 79 endovascular procedures performed...
Abstract BACKGROUND: The optimal revascularization strategy for symptomatic adult moyamoya remains controversial. Whereas direct bypass offers immediate revascularization, indirect can effectively induce collaterals over time. OBJECTIVE: Using angiography and quantitative magnetic resonance angiography, we examined the relative contributions of in patients after combined superficial temporal artery-to-middle cerebral artery (STA-MCA) encephaloduroarteriosynangiosis (EDAS). METHODS: A...
Background and Purpose— The hemodynamic effects of extracranial carotid stenosis on intracranial blood flow are not well characterized. We sought to determine the impact degree stenosis, length, residual lumen in patients with stenosis. Methods— Carotid who had undergone both vessel rate measurements using quantitative magnetic resonance angiography digital subtraction were examined. anatomic relative ipsilateral internal artery (ICA) ipsilateral-to-contralateral middle cerebral (MCA) ratio...
Background and Purpose— Atherosclerotic vertebrobasilar disease is an important cause of posterior circulation stroke. To examine the role hemodynamic compromise, a prospective multicenter study, Vertebrobasilar Flow Evaluation Risk Transient Ischemic Attack Stroke (VERiTAS), was conducted. Here, we report clinical features vessel flow measurements from study cohort. Methods— Patients with recent transient ischemic attack or stroke ≥50% atherosclerotic stenosis occlusion in vertebral basilar...
Embolization reduces flow in arteriovenous malformations (AVMs) before surgical resection, but achievement of this goal is determined subjectively from angiograms. Here, we quantify effects embolization on AVM flow.Records patients who underwent at our institution between 2007 and 2013 had rates obtained pre- postembolization using quantitative magnetic resonance angiography were retrospectively reviewed. Total was estimated as aggregate within primary arterial feeders or single draining...
Patients with intracranial arteriosclerotic disease have significant morbidity and mortality rates, some are unresponsive to medical treatment unacceptable surgical risks. Percutaneous transluminal angioplasty of the vessels is a possible alternative surgery.To present our experience percutaneous summarize data.Sixteen patients underwent for high-grade stenosis based on strict inclusion exclusion criteria. All had symptoms referable except one. Angioplasty was performed in 6 vertebral...
Background and Purpose— In-stent restenosis (ISR) after angioplasty/stenting for intracranial stenosis has been reported in up to 25% 30% of patients. Detection monitoring ISR relies primarily on serial catheter angiography, because noninvasive imaging methods are typically hampered by stent-related artifact. We examined the value vessel flow measurements using quantitative magnetic resonance angiography (QMRA) detection ISR. Material Methods— Records patients undergoing stenting symptomatic...
Covered stents are used endovascularly to seal arterial wall defects while preserving vessel patency. This report describes our experience with the use of covered treat cervical pathology, and a review literature in regards this topic is presented.Two patients presenting carotid blowout syndrome one patient vertebrojugular fistula were treated stents. allowed for preservation was treatment alternative cerebral bypass.Covered provide viable means vessels selected patients; however, long-term...
Background and Purpose— Wall shear stress (WSS) has been implicated as an important stimulus for vascular remodeling. The purpose of this study is to measure WSS in AVM arterial feeders using quantitative magnetic resonance angiography pre- post-embolization/surgery. Methods— Records patients who underwent embolization surgical resection at our institution between 2007 2013 had WSS, flow rate, vessel diameter obtained post-treatment were retrospectively reviewed. was compared the feeder...
Cerebral arteriovenous malformations (AVMs) have about a 2% to 4% annual risk of intracranial hemorrhage and are the most common cause in younger people, who subsequently at for long-term morbidity mortality.1-3 Thus, understanding is crucial determining appropriate treatment. Despite hemodynamic pathophysiology underlying AVMs, current AVM characterization assessment based largely on anatomical features derived from digital subtraction angiography rather than flow parameters.4,5...

Carotid artery stenting is an endovascular treatment option for patients with extracranial carotid stenosis. However, intracranial blood flow changes following have not been established.To determine the effects of on flow.Records who underwent at our institution between 2004 and 2012 had rates obtained pre- poststenting by use quantitative magnetic resonance angiography were retrospectively reviewed. Percentage stenosis, stenosis length, minimum vessel diameter measured from cerebral...
