Background and Purpose: Transient focal neurological episodes occur in cerebral amyloid angiopathy (CAA) and can mimic transient ischemic attack (TIA). Risk factors and outcomes of minor ischemic stroke or TIA might differ in patients with and without cerebral microbleeds (CMBs), including CAA-consistent lobar CMB.
Background and Purpose: To elucidate the predictors of antidepressant use after subarachnoid hemorrhage from saccular intracranial aneurysm (sIA-SAH) in a population-based cohort with matched controls.
Background and Purpose: High blood pressure is a major cause of cardiovascular events, and carotid flow pulsatility may be associated with cardiovascular events. However, the combined effect of blood pressure and flow pulsatility on the development of stroke remains unclear. Therefore, we investigated the combined influence of central blood pressure and pulsatility index (PI) on the incidence of stroke.
Background and Purpose: The risk of stroke recurrence in patients with Embolic Stroke of Undetermined Source (ESUS) is high, and the optimal antithrombotic strategy for secondary prevention is unclear. We investigated whether congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, and stroke or transient ischemic attack (TIA; CHADS2) and CHA2DS2-VASc scores can stratify the long-term risk of ischemic stroke/TIA recurrence and death in ESUS.
Background and Purpose: Brain infarct patterns that are observed via diffusion-weighted imaging are useful for classifying stroke subtypes. However, it is unclear whether infarct patterns can predict long-term outcomes in cryptogenic stroke patients. Herein, we investigated the association between acute brain infarct patterns and long-term stroke outcomes in cryptogenic stroke patients.
Background and Purpose: Computed tomographic perfusion represents an interesting physiological imaging modality to select patients for reperfusion therapy in acute ischemic stroke. The purpose of our study was to determine the accuracy of different commercial perfusion CT software packages (Philips (A), Siemens (B), and RAPID (C)) to predict the final infarct volume (FIV) after mechanical thrombectomy.
Background and Purpose: Initial diffusion-weighted imaging lesion growth rate (IGR) assessed by diffusion-weighted imaging lesion volume divided by the delay from onset to magnetic resonance imaging offers an estimate of early brain infarction progression. We investigated the impact of IGR on the rate of favorable outcome according to the occurrence of a successful endovascular revascularization within 6 hours after onset in patients experiencing an acute brain infarction complicating internal carotid artery terminus/middle cerebral artery M1 occlusion.
Background and Purpose: Thrombectomy, primarily with stent retrievers with or without adjunctive aspiration, provided clinical benefit across multiple prospective randomized trials. Whether this benefit is exclusive to stent retrievers is unclear.
Background and Purpose: Carotid artery revascularization was previously found to incrementally reduce stroke risk among patients with carotid stenosis treated with medical therapy. However, the frequency with which optimal medical therapies are used at discharge after carotid endarterectomy (CEA) and carotid artery stenting (CAS) is not known, and the influence of patient, operator, and hospital characteristics on the likelihood of prescription is poorly understood.
Background and Purpose: Intravenous tissue-type plasminogen activator (tPA) is a proven treatment for acute ischemic stroke, but there has been limited evaluation among patients aged ≥90 years.
Background and Purpose: We hypothesized that permanent stenting may be a rescue treatment for stentriever-failed anterior circulation large artery occlusion. We compared the outcomes among patients with permanent stenting and those without stenting after stentriever failure.
Background and Purpose: We performed a meta-analysis to assess whether leukoaraiosis on brain computed tomographic scans of acute ischemic stroke patients treated with intravenous thrombolysis is associated with an increased risk of symptomatic intracerebral hemorrhage (sICH) or poor functional outcome at 3 to 6 months after stroke, or both.
Background and Purpose: Patients with atrial fibrillation and previous ischemic stroke (IS)/transient ischemic attack (TIA) are at high risk of recurrent cerebrovascular events despite anticoagulation. In this prespecified subgroup analysis, we compared warfarin with edoxaban in patients with versus without previous IS/TIA.
Purpose: To implement a magnetic resonance (MR) imaging protocol to measure intracranial atherosclerotic disease (ICAD) in a population-based multicenter study and report examination and reader reliability of these MR imaging measurements and descriptive statistics representative of the general population.
Purpose: While today mechanical thrombectomy is an established treatment option for main branch occlusions in anterior circulation stroke, there is still an ongoing debate on the kind of anesthesia to be preferred. Introducing a simple method for head stabilization, we analyzed safety and duration of endovascular recanalization procedures under general anesthesia (GA) and conscious sedation (CS).
