Background and Purpose: Unenhanced time-resolved spin-labeled magnetic resonance angiography enables hemodynamic quantification in arteriovenous malformations (AVMs). Our purpose was to identify quantitative parameters that discriminate among different AVM components and to relate hemodynamic patterns with rupture risk.
Background and Purpose: We investigated whether family history of stroke or coronary heart disease (CHD) is associated with presence of carotid artery stenosis (CAS).
Background and Purpose: This study aimed to monitor cognitive performance during a 3-year period in subjects with bilateral asymptomatic severe internal carotid artery stenosis and to explore the role of cerebral hemodynamics and atherosclerotic disease in the development of cognitive dysfunction.
Background: Flow-diverting stents offer a promising treatment option for complex aneurysms.
Background: Long-term outcomes associated with endovascular and surgical treatments for unruptured intracranial aneurysms are not well studied to date.
Background: Treatment of internal carotid ruptured blister aneurysms (IC-RBA) presents many challenges to neurosurgeons because of the high propensity for rebleeding during intervention. The role of a Pipeline Embolization Device (PED) in the treatment of this challenging aneurysm subtype remains undefined despite theoretical advantages.
Background: Intraoperative angiography (IA) is used to evaluate the adequacy of clip reconstruction of intracranial aneurysms. Alternative imaging such as indocyanine green videoangiography (ICG-VA) has been proposed. The additional benefit of ICG-VA when IA is routinely used has not been previously determined.
Background and Purpose: Coated-platelets, a subset of procoagulant platelets observed on dual agonist stimulation with collagen and thrombin, support a robust prothrombinase activity and provide a unique measure of platelet thrombotic potential. Coated-platelet levels are increased in large artery stroke, and higher levels are associated with early stroke recurrence, suggesting a potential role for risk stratification in asymptomatic patients with carotid artery stenosis.
Background and Purpose: Neovascularization associated with plaque vulnerability, particularly in the plaque shoulder, is susceptible to rupture, causing ischemic events. We aimed to use contrast-enhanced ultrasound to evaluate neovessels in carotid plaques quantitatively, focusing on plaque shoulders.
Background and Purpose: Cerebral microbleeds (CMBs) are found in a substantial proportion of patients with ischemic stroke eligible for treatment with intravenous thrombolysis. Until now, there is limited data on the impact of multiple CMBs on occurrence of intracerebral hemorrhage (ICH) after intravenous thrombolysis.
Background and Purpose: The pathogenesis of cerebral aneurysms still raises some controversies. The aim of this study was to identify morphological, hemodynamic, and clinical independent risk factors for anterior communicating artery (ACoA) aneurysm development.
Background and Purpose: Several endovascular treatment options are available for cavernous carotid aneurysms. We compared pipeline embolization device (PED) versus conventional endovascular treatment in terms of evolution of mass effect, complications, recurrence, and retreatment rate.
Background and Purpose: We aimed at comparing the long-term benefit–risk balance of carotid stenting versus endarterectomy for symptomatic carotid stenosis.
Purpose: Stroke with tandem occlusion within the anterior circulation presents a lower probability of recanalization and good clinical outcome after intravenous (IV) thrombolysis than stroke with single occlusion. The present study describes the impact of endovascular procedures (EPs) compared with IV thrombolysis alone on recanalization and clinical outcome.
Background and Purpose: Ability to perform basic daily activity represented by functional status (FNS) before surgery can be assessed in the clinic for determining health status of the patient. We sought to study the effect of FNS on postoperative outcomes after carotid endarterectomy (CEA) in a national data set.
