Ina Israel, Felix Fluri, Fabian Schadt, Adreas Buck, Samuel Samnick
BACKGROUND: P-selectin is activated early after stroke, followed by a rapid decline. This time course can be used to generate important information on stroke onset. The latter is crucial for therapeutic decision-making of wake-up strokes (i.e. thrombolysis or not). Here we evaluated the specific p-selectin inhibitor 68Ga-Fucoidan for assessing p-selectin activation after ischemic stroke using PET. METHODS: 68Ga-Fucoidan was investigated in rats brain at 2-5 h (n=16), and additionally at 24-26 h (n=9) and 48 h (n=3) after induction of photothrombic stroke or in sham operated animals (n=6)...

Background: In regional and rural Australia, patients experiencing ischemic stroke do not have equitable access to an intravenous recombinant tissue plasminogen activator (tPA). Although thrombolysis with tPA is a clinically proven and cost-effective treatment for eligible stroke patients, there are few economic evaluations on pre-hospital triage interventions to improve access to tPA. Aim: To describe the potential cost-effectiveness of the pre-hospital acute stroke triage (PAST) protocol implemented to provide priority transfer of appropriate patients from smaller hospitals to a primary stroke center (PSC) in regional New South Wales, Australia...

Background: Duchenne muscular dystrophy (DMD) is an X-linked recessive skeletal muscle myopathy which is caused by mutations in the dystrophin gene. Lack of dystrophin also results to cardiomyopathy, which raises significantly the stroke risk in DMD-patients. However, data about therapeutic opportunities in the acute setting are scarce in literature. So far, only two cases receiving IV thrombolysis are described, one of them with fatal outcome. Method: Case report of a case of successful mechanical thrombectomy (MTE) in an acute ischemic stroke (AIS) patient with DMD and associated dilatative cardiomyopathy...

BACKGROUND: Recent reports showing the favorable role of patent foramen ovale (PFO) closure in patients with cryptogenic stroke have raised the issue of selecting optimal candidates. OBJECTIVES: We evaluated whether the benefits of PFO closure can be determined based on the morphologic characteristics of the PFO, as evaluated by transesophageal echocardiography. METHODS: Patients with cryptogenic stroke and high-risk PFO were divided between a transcatheter PFO closure and a medication-only group...

In this pilot study, we have evaluated bedside diffuse optical monitoring combining diffuse correlation spectroscopy and near-infrared diffuse optical spectroscopy to assess the effect of thrombolysis with an intravenous recombinant tissue plasminogen activator (rtPA) on cerebral hemodynamics in an acute ischemic stroke. Frontal lobes of five patients with an acute middle cerebral artery occlusion were measured bilaterally during rtPA treatment. Both ipsilesional and contralesional hemispheres showed significant increases in cerebral blood flow, total hemoglobin concentration and oxy-hemoglobin concentration during the first 2...

Introduction While effectiveness of mechanical thrombectomy (MTE) in M1 segment occlusion is approved for patients with severe impairment, there is a lack of evidence for a potential benefit of MTE in patients with minor to moderate symptoms. The purpose of this study was to evaluate neurological outcome and occurrence of periprocedural complications after MTE in patients with low National Institutes of Health Stroke Scale (NIHSS) scores. Materials and methods A retrospective analysis of 1081 consecutive patients with anterior circulation ischemic stroke due to M1 occlusion detected by computed tomography angiography and treated with MTE at our hospital between February 2012 and November 2017 was performed...

BACKGROUND AND PURPOSE: The majority of ischemic stroke patients receiving endovascular recanalization therapy (EVT) experience variable changes of neurological severities during the hyperacute period. We hypothesized that the National Institutes of Health Stroke Scale (NIHSS) score after EVT is a better prognostic factor compared with the initial NIHSS score or revascularization status. METHODS: We identified 566 stroke patients who received EVT at Seoul National University Bundang Hospital between April 2008 and December 2015...

BACKGROUND: Informing health systems and monitoring hospital performances using administrative data sets, mainly hospital discharge data coded according to International-Classification-Diseases-9edition-Clinical-Modifiers (ICD9-CM), is now commonplace in several countries, but the reliability of diagnostic coding of acute ischemic stroke in the routine practice is uncertain. This study aimed at estimating accuracy of ICD9-CM codes for the identification of acute ischemic stroke and the use of thrombolysis treatment comparing hospital discharge data with medical record review in all the six hospitals of the Florence Area, Italy, through 2015...

REVIVE SE (REVIVE) is a closed-ended, self-expanding stent retriever used in the RIVER JAPAN study. We present our early experience with REVIVE for revascularization of acute ischemic stroke (AIS) in patients who have failed or are ineligible for intravenous recombinant tissue plasminogen activator treatment. This prospective, single-arm, non-randomized, multicenter registry study followed up patients undergoing mechanical thrombectomy with REVIVE for 90 days. The primary endpoint was a post-procedure Thrombolysis in Cerebral Infarction (TICI) score ≥2a...

Some stroke patients with the acute aortic dissection receiving thrombolysis treatment resulted in fatalities. Thus, the concurrent acute aortic dissection is the contraindication for the intravenous recombinant tissue-type plasminogen activator. However, the safety and the effectiveness of the intravenous recombinant tissue-type plasminogen activator therapy are not known in patients with stroke some days after acute aortic dissection treatment. Here, we first report a case of a man with a cardioembolism due to the nonvalvular atrial fibrillation, who received the intravenous recombinant tissue-type plasminogen activator therapy 117 days after the traumatic Stanford type A acute aortic dissection operation...

BACKGROUND: Whether intravenous thrombolysis (IVT) prior to mechanical thrombectomy (MT) provides additional benefits remains controversial. We aimed to compare clinical and radiologic outcomes between IVT+MT and MT alone groups. METHODS: The clinical and radiological features of anterior circulation stroke patients due to large vessel occlusion (LVO) treated with MT within 8 hours from symptom onset were retrospectively reviewed from the prospectively collected database...

Acute stroke therapy has significantly evolved over the last two decades. The two main advances have been the approval of intravenous chemical thrombolysis in 1995, and the approval of intra-arterial mechanical thrombectomy in 2015. This has lead to significant improvement of functional outcomes in a disease known to be the first cause of disability worldwide. Subsequent studies have focused on identifying pre-treatment predictors of good treatment candidates, by developing biochemical and imaging biomarkers...

Background: Symptomatic intracranial hemorrhage (sICH) after intravenous thrombolysis with recombinant tissue-plasminogen activator (rt-PA) for acute ischemic stroke is associated with a poor functional outcome. We aimed to develop a score assessing risk of sICH including novel putative predictors-namely, pretreatment with statins and severe renal impairment. Methods: We analyzed our local cohort (Berlin) of patients receiving rt-PA for acute ischemic stroke between 2006 and 2016...

BACKGROUND: Acute ischemic stroke (AIS) is a medical emergency. The outcome is closely linked to the time elapsing from symptom onset to treatment, and seemingly small delays can mean the difference between full recovery and physical and cognitive dysfunction. Recanalization to allow blood to reenter the affected area is most efficient immediately after symptoms occur, and intravenous thrombolysis must be initiated no later than 4.5 hours after the symptom onset. A liable diagnosis is mandatory to administer the appropriate treatment...

Acute thrombotic occlusions of the large vessels, such as internal carotid artery, arms and legs arteries, and intracranial vessels, frequently require multiple techniques such as selective thrombolysis, manual aspiration, and stent retrievers for mechanical thrombectomy with combination of the mentioned techniques. Because of the massive thrombotic burden associated with these conditions, the response to systemic intravenous thrombolysis is poor. We present a case of a successful massive thrombi aspiration in a single attempt using an 8Fr guide catheter with aspiration syringe, subsequent ipsilateral middle cerebral artery mechanical thrombectomy, and axillary artery clot disruption attempt in a patient with acute ischemic stroke, right arm critical ischemia, and persistent atrial fibrillation...
