Background: For patients meeting eligibility criteria, endovascular thrombectomy (EVT) remains the gold standard treatment for acute ischemic stroke (AIS) caused by large vessel occlusion (LVO). A few randomized trials have investigated EVT in AIS-LVO with infarcts (LII). We studied impact of intravenous thrombolysis (IVT) on outcomes those patients. Methods: conducted a meta-analysis using Preferred Reporting Items Systematic Reviews and Meta-Analyses (PRISMA) checklist Cochrane Handbook...

Endovascular thrombectomy (EVT) is the standard treatment for acute ischemic stroke (AIS) caused by large vessel occlusion (LVO). Transradial access (TRA) has emerged as an alternative to traditional transfemoral (TFA), showing promise in reducing access-site complications. This systematic review and meta-analysis aim comprehensively assess procedural clinical outcomes of TRA versus TFA EVT AIS-LVO patients. Following Preferred Reporting Items Systematic Reviews Meta-Analysis guidelines, we...

Understanding the potential embolic source in young patients with ESUS may improve diagnosis and treatment of such patients.Potential sources (PES) differ vs. older ESUS, and, therefore, not all have same risk profile for stroke recurrence.Young (age 18-49) who were admitted to our center from 2006 2019, identified retrospectively matched next consecutive 50-99) by admission date. PES categorized as atrial cardiopathy, AFib diagnosed during follow-up, left ventricular disease (LVD), cardiac...

Trans-radial access (TRA) for MMA embolization has grown due to lower site complications and greater patient satisfaction. Here, we describe the feasibility of utilizing a 6F Envoy Simmons 2 (6F-SIM2) as guide catheter with TRA compare outcomes trans-femoral approach (TFA) in single center case series.We performed retrospective review patients who underwent management chronic subdural hematoma (cSDH). was by combination 90cm (Codman & Shurtleff, Inc., Rayham, MA) 5F 125cm Sofia...

NA. Over the past decade, Tenecteplase (TNK) has been proposed as an alternative thrombolytic agent to alteplase in adult acute ischemic stroke (AIS) patients. However, there is no data on TNK use pediatric population. The most updated guidelines recommend tPA for children >2 yrs old with disabling neurological deficits within 4.5 hrs from symptom onset. more fibrin specific and resistance plasminogen activator inhibitor, therefore may achieve better clot lysis compared alteplase. limited...

Background Moyamoya disease (MMD) is a rare pathological state characterized by progressive stenosis of the terminal portion internal carotid arteries (ICA). Complications include both ischemic and hemorrhagic strokes, for which there no curative treatment MMD. Early diagnosis with surgical intervention vital definitive treatment. Due to bimodal age distribution, moyamoya should be considered patients presenting stroke supraclinoid ICA vasculopathy. Case We present case 23-year-old female...

Objective: This study is a post-hoc analysis of the Interventional Management Stroke (IMS) III trial investigating burden white matter hyperintensities (WMH), using van Swieten Scale (VSS), on functional outcomes for acute ischemic stroke (AIS) patients treated with either intravenous thrombolysis (IVT) or IVT mechanical thrombectomy (MT). Background: WMH are well-established marker underlying cerebral microvascular disease. VSS quantifies disease from zero to four higher numbers signifying...

<h3>Introduction</h3> Chronic subdural hematoma is a common neurosurgical condition with high recurrence rate. The primary pathologic process repeated micro bleedings from fragile neo-vessels which are supplied by peripheral branches of the middle meningeal artery (MMA). MMA embolization has been shown to reduce incidence re-bleeding and prevent cSDH devascularizing membranes shifting balance continued leakage accumulation blood proteinaceous material reabsorption. Liquid embolic particle...

Background: Inpatient acute stroke identification may be challenging given the complexity related to both concomitant and comorbid illness. Rapid accurate diagnosis requires a skilled clinician discern patients from other mimics such as hypoglycemia, hemiplegic migraine, post-ictal paresis, relapse of demyelinating disease, or recrudescence prior stroke. Hypothesis: Negative predictors can identified in inpatients with inpatient alerts. Methods: IRB approved, retrospective analysis...

Introduction Chronic subdural hematoma (cSDH) is one of the most common neurosurgical diagnoses with a high recurrence rate in aging population. The primary pathologic process repeated micro bleeding from fragile neo‐vessels supplied by peripheral branches middle meningeal artery (MMA).

They make up 1.5% more than 90% AVMs located intracranially1. Extracranial predominantly in can manifest with pain, ulcerations, fatal hemorrhage, airway compromise, cosmetic aberrations1,2.

Introduction Mechanical thrombectomy (MT) is the gold standard for acute ischemic stroke (AIS) due to large vessel occlusion (LVO). Although &gt;70% of patients in randomized clinical trials (RCTs) assessing efficacy MT AIS‐LVO had successful recanalization, only up 27% were free disability according 90‐day modified Rankin scale (mRS) score. It suggested that microcirculation disruption distal LVO might contribute futile recanalization. Hence, combining intra‐arterial (IA) tissue plasminogen...

Introduction Endovascular thrombectomy (EVT) is the gold standard treatment for patients with acute ischemic stroke (AIS) caused by large vessel occlusion (LVO), and there are several factors that can influence outcomes of EVT in AIS‐LVO patients. We conducted this meta‐analysis to investigate effect cerebral microbleeds (CMBs) on functional safety AIS LVO.
