Inadvertent hypothermia after endovascular therapy is not associated with improved outcome in stroke due to anterior circulation large vessel occlusion.

Background And Purpose: Hypothermia may be neuroprotective in acute ischemic stroke. Patients with anterior circulation large vessel occlusion (acLVO) are frequently hypothermic after endovascular therapy (EVT). We sought to determine whether this inadvertent hypothermia is associated with improved outcome.

Acute kidney injury in patients with malignant middle cerebral artery infarction undergoing hyperosmolar therapy with mannitol.

Purpose: To assess the kidney safety profile of mannitol in patients with malignant middle cerebral artery (MCA) infarction.

Material And Methods: We studied consecutive patients with malignant MCA infarction (01/2008-01/2018). Malignant MCA infarction was defined according to DESTINY criteria.

Universal laboratory testing for SARS-CoV-2 in hyperacute stroke during the COVID-19 pandemic.

Objective: Stroke patients are thought to be at increased risk of Coronavirus Disease 2019 (COVID-19). To evaluate yield of universal laboratory testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in acute stroke patients and its impact on hyperacute stroke care.

Methods: Between weeks 14 and 18 in 2020, a protected code stroke protocol including infection control screening and laboratory testing for SARS-CoV-2 was prospectively implemented for all code stroke patients upon arrival to the emergency department.

Association of Hypertensive Intracerebral Hemorrhage with Left Ventricular Hypertrophy on Transthoracic Echocardiography.

Introduction: Arterial hypertension is the most frequent cause for spontaneous intracerebral hemorrhage (sICH) and may also cause left ventricular hypertrophy (LVH). We sought to analyze whether hypertensive sICH etiology is associated with LVH.

Methods: We analyzed consecutive patients with sICH who were admitted to our tertiary stroke center during a four-year period and underwent transthoracic echocardiography (TTE) as part of the diagnostic work-up.

Safety of inter-hospital transfer of patients with acute ischemic stroke for evaluation of endovascular thrombectomy.

Stroke networks facilitate access to endovascular treatment (EVT) for patients with ischemic stroke due to large vessel occlusion. In this study we aimed to determine the safety of inter-hospital transfer and included all patients with acute ischemic stroke who were transferred within our stroke network for evaluation of EVT between 06/2016 and 12/2018. Data were derived from our prospective EVT database and transfer protocols.

Endovascular therapy for anterior circulation large vessel occlusion in telestroke.

Introduction: Recent exploratory analysis suggested comparable outcomes among stroke patients undergoing endovascular therapy (EVT) for anterior circulation large vessel occlusion, whether selected via the telestroke network or admitted directly to an EVT-capable centre. We further studied the role of telemedicine in selection of ischaemic stroke patients potentially eligible for EVT.

Methods: We prospectively included consecutive ischaemic stroke patients with anterior circulation large vessel occlusion who underwent EVT at our neurovascular centre (January 2016 to March 2018).

Association of Anesthetic Exposure Time With Clinical Outcomes After Endovascular Therapy for Acute Ischemic Stroke.

The optimal sedative regimen with general anesthesia (GA) or conscious sedation for patients undergoing endovascular therapy (EVT) remains controversial. Apart from sedative regimen, the duration of anesthetic exposure may affect clinical outcomes. We aimed to determine whether there is an association between anesthetic exposure time and clinical outcomes in mechanically ventilated stroke patients undergoing EVT for large vessel occlusion.

Misjudgment of pre-stroke functional status contradicts beneficial outcomes after endovascular therapy for large vessel occlusion.

Endovascular therapy (EVT) trials enrolled ischemic stroke patients with good pre-stroke functional status. However, this information needed for rapid decision-making is commonly lacking in clinical practice. We hypothesized that initial misjudgment of pre-stroke functional status attenuates clinical outcomes of EVT.

Low Diagnostic Yield of Routine Cerebrospinal Fluid Analysis in Juvenile Stroke.

The diagnostic value of cerebrospinal fluid (CSF) analysis in juvenile stroke, i.e., stroke in young adult patients, is not well studied.

Standardized use of novel oral anticoagulants plasma level thresholds in a new thrombolysis decision making protocol.

Acute ischemic stroke (AIS) patients receiving non-vitamin-K antagonist oral anticoagulants (NOAC) are commonly excluded from thrombolytic therapy, as interpretation of coagulation tests remains unclear. We aimed to investigate the applicability of a novel institutional protocol for thrombolysis based on current expert recommendations and NOAC specific coagulation assessment. We included hospitalized AIS patients receiving NOAC for at least 24 h and consecutive AIS patients not receiving NOAC into a prospective study.

Continuous non-invasive monitoring of tidal volumes by measurement of tidal impedance in neonatal piglets.

Background: Electrical Impedance measurements can be used to estimate the content of intra-thoracic air and thereby give information on pulmonary ventilation. Conventional Impedance measurements mainly indicate relative changes, but no information concerning air-volume is given. The study was performed to test whether a 3-point-calibration with known tidal volumes (VT) during conventional mechanical ventilation (CMV) allows subsequent calculation of VT from total Tidal-Impedance (tTI) measurements using Quadrant Impedance Measurement (QIM).
