Rescue stenting after failed mechanical thrombectomy: The RES-CAT study.

Introduction: The efficacy of intracranial rescue stenting (RS) following failed mechanical thrombectomy (MT) in large-vessel occlusion (LVO) stroke remains uncertain. We aimed to evaluate clinical outcomes of RS in patients with anterior circulation LVO stroke following unsuccessful MT.

Patients And Methods: We conducted a retrospective analysis using the Stroke Code Registry of Catalonia (January 2016-March 2022), a prospective, population-based registry including patients treated at 10 comprehensive stroke centers.

A Randomized Trial on Hemodynamic Optimization of Cerebral Perfusion after Successful Endovascular Therapy in Patients with Acute Ischemic Stroke (HOPE).

Introduction: In patients with acute ischemic stroke (AIS) secondary to intracranial large vessel occlusion, optimal blood pressure (BP) management following endovascular treatment (EVT) has not yet been established. The randomized trial on Hemodynamic Optimization of Cerebral Perfusion after Successful Endovascular Therapy in Patients with Acute Ischemic Stroke (HOPE) (clinicaltrials.gov id: NCT04892511) aims to demonstrate whether hemodynamic optimization using different systolic BP targets following EVT according to the degree of final recanalization, is more effective than currently recommended BP management in improving functional outcomes of patients with AIS.

Influence of Hospital Type on Outcomes of Patients With Acute Spontaneous Intracerebral Hemorrhage: A Population-Based Study.

Background And Objectives: Whether the outcome of patients with spontaneous intracerebral hemorrhage (ICH) differs depending on the type of hospital where they are admitted is uncertain. The objective of this study was to determine influence of hospital type at admission (telestroke center [TSC], primary stroke center [PSC], or comprehensive stroke center [CSC]) on outcome for patients with ICH. We hypothesized that outcomes may be better for patients admitted to a CSC.

Early automated cerebral edema assessment following endovascular therapy: impact on stroke outcome.

Background: Cerebral edema (CED) is associated with poorer outcome in patients with acute ischemic stroke (AIS). The aim of the study was to investigate the factors contributing to greater early CED formation in patients with AIS who underwent endovascular therapy (EVT) and its association with functional outcome.

Methods: We conducted a multicenter cohort study of patients with an anterior circulation AIS undergoing EVT.

Left atrial appendage occlusion in patients with spontaneous intracerebral hemorrhage: An observational study.

Background: Patients with atrial fibrillation (AF) and intracerebral hemorrhage (ICH) are at high risk of ischemic and recurrent bleeding events. Therefore, the decision of restarting or avoiding anticoagulation is challenging. Left atrial appendage occlusion (LAAO) is an alternative for these patients.

Asymptomatic parenchymal haemorrhage following endovascular treatment: Impact on functional outcome in patients with acute ischaemic stroke.

Background And Purpose: In patients with acute ischaemic stroke (AIS), haemorrhagic transformation (HT) following endovascular treatment (EVT) is associated with poor functional outcome. However, the impact of asymptomatic HT, not linked to neurological deterioration in the acute phase, is unknown. We aimed to investigate the impact of asymptomatic PH1 (aPH1) and PH2 (aPH2) subtypes of HT on the functional outcome of patients treated with EVT.

Clinical characteristics and outcome of amaurosis fugax due to transient retinal ischemia: Results from a contemporary cohort.

Background: Whether presenting an episode of amaurosis fugax (AFx) increases the risk of ischemic stroke is controversial and there is a lack of consensus in the following management. We aimed to describe the clinical characteristics and prognosis of patients with AFx due to suspected transient retinal ischemia.

Methods: Observational, retrospective study of patients admitted in a Comprehensive Stroke Center with diagnosis of AFx due to suspected transient retinal ischemia between 2015 and 2020.

Electronegative LDL Is Associated with Plaque Vulnerability in Patients with Ischemic Stroke and Carotid Atherosclerosis.

Owing to the high risk of recurrence, identifying indicators of carotid plaque vulnerability in atherothrombotic ischemic stroke is essential. In this study, we aimed to identify modified LDLs and antioxidant enzymes associated with plaque vulnerability in plasma from patients with a recent ischemic stroke and carotid atherosclerosis. Patients underwent an ultrasound, a CT-angiography, and an F-FDG PET.

Automated scoring of collaterals, blood pressure, and clinical outcome after endovascular treatment in patients with acute ischemic stroke and large-vessel occlusion.

Introduction: We aimed to determine whether the degree of collateral circulation is associated with blood pressure at admission in acute ischemic stroke patients treated with endovascular treatment and to determine its prognostic value.

Methods: We evaluated patients with anterior large vessel occlusion treated with endovascular treatment in a single-center prospective registry. We collected clinical and radiological data.

Determinants and Trends of the Use of Intravenous Thrombolysis for Minor Stroke: A Population-Based Study, 2016 to 2020.

Background: We analyzed the main factors associated with intravenous thrombolysis (IVT) in patients with minor ischemic stroke.

Methods: Data were obtained from a prospective, government-mandated, population-based registry of stroke code patients in Catalonia (6 Comprehensive Stroke Centers, 8 Primary Stroke Centers, and 14 TeleStroke Centers). We selected patients diagnosed with ischemic stroke and National Institutes of Health Stroke Scale (NIHSS) ≤5 at hospital admission from January 2016 to December 2020.

Association of Plaque Inflammation With Stroke Recurrence in Patients With Unproven Benefit From Carotid Revascularization.

Background And Objectives: In pooled analyses of endarterectomy trials for symptomatic carotid stenosis, several subgroups experienced no net benefit from revascularization. The validated symptomatic carotid atheroma inflammation lumen-stenosis (SCAIL) score includes stenosis severity and inflammation measured by PET and improves the identification of patients with recurrent stroke compared with lumen-stenosis alone. We investigated whether the SCAIL score improves the identification of recurrent stroke in subgroups with uncertain benefit from revascularization in endarterectomy trials.

Frequency, Predictors, Etiology, and Outcomes for Deep Intracerebral Hemorrhage without Hypertension.

Objectives: Some patients with deep intracerebral hemorrhage (ICH) have a transient hypertensive response and they may be erroneously classified as secondary to hypertension. We investigated frequency, risk factors, and outcomes for patients with deep ICH without hypertension.

Materials And Methods: We consecutively recruited patients with spontaneous ICH attending two Spanish stroke centers (January 2015-June 2019).

Endothelial Progenitor Cells Count after Acute Ischemic Stroke Predicts Functional Outcome in Patients with Carotid Atherosclerosis.

Objectives: Circulating Endothelial Progenitor Cells (EPCs) predict cardiovascular outcomes in patients with coronary disease. However, the predictive value of EPCs after ischemic stroke is not well established. We aimed to study the prognostic role of EPCs in patients with acute ischemic stroke and carotid atherosclerosis, focusing on post-stroke functional outcome and stroke recurrences.

Impact of COVID-19 Infection on the Outcome of Patients With Ischemic Stroke.

Background And Purpose: We evaluated whether stroke severity, functional outcome, and mortality are different in patients with ischemic stroke with or without coronavirus disease 2019 (COVID-19) infection.

Methods: A prospective, observational, multicentre cohort study in Catalonia, Spain. Recruitment was consecutive from mid-March to mid-May 2020.

Patterns of Admission and Outcomes for Patients with Intracranial Hemorrhage in Catalonia, Spain.

Background: Limited information is available about the hospital types to which patients with intracerebral hemorrhage (ICH) are admitted and treated. This could be important because some effective therapeutic measures can only be administered at comprehensive stroke centers (CSCs).

Methods: Using the Acute Hospitals Discharge database, which provides population-based information, we identified ICH patients admitted to 7 CSCs and 53 non-CSCs (from January 2015 to December 2016) in Catalonia.

Clinical and radiological characteristics and outcome of wake-up intracerebral hemorrhage.

There is little information on the characteristics of patients with wake-up intracerebral hemorrhage (WU-ICH). We aimed to evaluate frequency and relevant differences between WU-ICH and while-awake (WA) ICH patients. This is a retrospective study of a prospective database of consecutive patients with spontaneous ICH, who were classified as WU-ICH, WA-ICH or UO-ICH (unclear onset).

Influence of time to admission to a comprehensive stroke centre on the outcome of patients with intracerebral haemorrhage.

Introduction: In patients with spontaneous intracerebral haemorrhage, it is uncertain if diagnostic and therapeutic measures are time-sensitive on their impact on the outcome. We sought to determine the influence of the time to admission to a comprehensive stroke centre on the outcome of patients with acute intracerebral haemorrhage.

Patients And Methods: We studied a prospective database of consecutive patients with intracerebral haemorrhage attended at two comprehensive stroke centres (2005-2017).
