BACKGROUND: A shortage of computed tomographic (CT) machines in low and middle income countries often results in delayed CT imaging for patients suspected of a stroke. Yet, time constraint is one of the most important aspects for patients with an ischemic stroke to benefit from thrombolytic therapy. We set out to assess whether application of the Siriraj Stroke Score is able to assist physicians in prioritizing patients with a high probability of having an ischemic stroke for urgent CT imaging...

BACKGROUND AND PURPOSE: Stroke is a leading cause of death in China. Yet the adherence to guideline-recommended ischemic stroke performance metrics in the past decade has been previously shown to be suboptimal. Since then, several nationwide stroke quality management initiatives have been conducted in China. We sought to determine whether adherence had improved since then. METHODS: Data were obtained from the 2 phases of China National Stroke Registries, which included 131 hospitals (12 173 patients with acute ischemic stroke) in China National Stroke Registries phase 1 from 2007 to 2008 versus 219 hospitals (19 604 patients) in China National Stroke Registries phase 2 from 2012 to 2013...

INTRODUCTION: Tandem occlusion resulting in acute ischemic stroke (AIS) is associated with high morbidity and mortality and a poor response to thrombolytic therapy. The use of endovascular strategies for tandem stroke cases results in an improved outcome for this subgroup of patients. We present two cases with a pattern of tandem occlusion consisting of proximal obstruction at the origin of the common carotid artery (CCA) with concomitant intracranial occlusion treated by endovascular techniques...

The administration of thrombolytic therapy in elderly patients with dementia and acute ischemic stroke may be controversial, because the reported risk of rt-PA associated intracerebral hemorrhage in these patients is higher compared with that of patients without dementia and because these patients are already disabled. Moreover, there are known risk factors for hemorrhagic transformation in patients with dementia: amyloid angiopathy, leukoaraiosis and the presence of microbleeds. In this review, we describe the impact of dementia on functional outcome following thrombolytic therapy for acute ischemic stroke and discuss some of the issues related to the use of this therapy in this specific patient's population...

Over the last decade considerable advances have been made in the identification, understanding and management of pediatric arterial ischemic stroke. Such increasing knowledge has also brought new perspectives and interrogations in the current acute and rehabilitative care of these patients. Areas covered: In developed countries, focal cerebral arteriopathy is one of the most common causes of arterial ischemic stroke in childhood and imaging features are well characterized. However, there are ongoing debates regarding its underlying mechanisms, natural evolution and proper management...

BACKGROUND: Citation bias occurs when positive trials involving a medical intervention receive more citations than neutral or negative trials of similar quality. Several large clinical trials have studied the use of thrombolytic agents for the treatment of acute ischemic stroke with differing results, thereby presenting an opportunity to assess these trials for evidence of citation bias. We compared citation rates among positive, neutral, and negative trials of alteplase (tPA) and other thrombolytic agents for stroke...

BACKGROUND: Interventional strategies for massive and submassive Pulmonary Embolism (smPE) have historically included either systematic intravenous thrombolytic alteplase (IV TPA) or surgical embolectomy, both of which are associated with significant morbidity and mortality. However, with the advent of endovascular techniques, recent studies have suggested that an endovascular approach to the treatment of acute smPE may be both safe and effective with excellent outcomes. The purpose of this study was to evaluate the outcomes of patients who have undergone catheter directed thrombolysis (CDT) for smPE at our institution in an effort to determine the safety of the procedure...

Vascular occlusion by the thrombi is the main reason for ischemic stroke and deep vein thrombosis. High-intensity focused ultrasound (HIFU) and histotripsy or microtripsy pulses can effectively dissolve the blood clot with no use of thrombolytic agent and ultrasound contrast agent (microbubbles). In this study, HIFU bursts at the same duty cycle (2%) but varied pulse repetition frequency (PRF) from 1Hz to 1000Hz were delivered to in vitro porcine blood clot for 30s. Thrombolysis efficiency initially increases slightly with the PRF, 86...

Deep venous thrombosis (DVT) is a common disorder with a significant mortality rate. Successful endovascular treatment of acute DVT is most likely to be achieved in patients with recently formed thrombus, (<10-14 days) with acute iliofemoral DVT. Endovascular treatment options include: Catheter-directed thrombolysis (CDT), pharmacomechanical catheter-directed thrombolysis (PCDT), percutaneous aspiration thrombectomy (PAT), vena cava filter protection, venous balloon dilatation and venous stent implantation...

This review surveys the efforts taken to achieve clinically efficacious protection of the ischemic brain and underscores the necessity of expanding our purview to include the essential role of cerebral perfusion and the collateral circulation. We consider the development of quantitative strategies to measure cerebral perfusion at the regional and local levels and the application of these methods to elucidate flow-related thresholds of ischemic viability and to characterize the ischemic penumbra. We stress that the modern concept of neuroprotection must consider perfusion, the necessary substrate upon which ischemic brain survival depends...

OBJECTIVE: We performed a systematic review and meta-analysis to assess whether the presence of cerebral microbleeds (CMBs) on pretreatment MRI of patients with acute ischemic stroke treated with IV thrombolysis is associated with increased risk of symptomatic intracerebral hemorrhage (ICH) and poor functional outcome. METHODS: We searched PubMed for relevant studies and calculated pooled odds ratios (OR) for symptomatic ICH and poor (i.e., modified Rankin Scale score >2) 3- to 6-month functional outcome using random effects models with DerSimonian-Laird weights among individuals with vs without CMBs...

The aims of this study were to examine prospectively the course of neurological and functional recovery and health related quality of life (HRQoL) in ischaemic stroke patients after intravenous thrombolysis, to assess the 1-year outcome and to determine the early predictors. A group of 53 consecutive patients were assessed at admission to the acute stroke unit (T0), before their discharge (T1), and at 3 (T2) and 12 (T3) months after hospital discharge. The National Institutes of Health Stroke Scale (NIHSS), the Barthel Index (BI) and the Stroke Specific Quality of Life Scale (SSQoL) were used to evaluate stroke severity, functional disability and health related quality of life (HRQoL)...

Ischemic stroke is the fourth leading cause of death in the USA and a prominent cause of death globally. Besides thrombolytic therapy used in a small subset of patients, no alternative therapeutic strategy has been shown to improve the outcome of stroke patients. Preclinical models of ischemic stroke are an essential tool for investigating pathogenic processes that happen after the ischemic insult, as well as to screen for candidate therapeutic interventions. There are several models of rodent ischemic stroke including mechanical occlusion, thromboembolic stroke, and photothrombotic stroke...

BACKGROUND: The limited efficacy of thrombolytic therapy in patients with ischemic stroke has created the need to use focused ultrasound (FUS) energy as a way to enhance thrombolysis efficacy (sonothrombolysis). Using an in vitro circulating flow model, we evaluated the role of physical parameters on tenecteplase (TNK-tPA)-mediated thrombolysis. MATERIALS AND METHODS: Fully retracted porcine blood clots were used for the proposed experimental study. To provide a more realistic clinical environment of stroke, the study was conducted under realistic flow conditions and TNK-tPA concentrations...

BACKGROUND: The location of acute ischemic infarct can affect the clinical outcome of stroke patients. We aimed to develop a prognostic tool based on the topographic distribution of early ischemic changes on admission computed tomography (CT) scans. METHODS: Using the albumin in acute stroke (ALIAS) trials dataset, patients with anterior circulation stroke were included for analysis. A 3-month modified Rankin scale (mRs) score > 2 defined disability/death; and ≤2 defined favorable outcome...

BACKGROUND AND PURPOSE: The development of intracerebral hemorrhage following intravenous thrombolysis (IVT) can be influenced by various confounders related to the underlying vessel and tissue conditions. There are some data on association of cause of the stroke and the hemorrhage transformation. We tested the hypothesis that the cause of stroke is associated with the development of symptomatic intracerebral hemorrhage (sICH) following IVT. METHODS: A consecutive cohort of 2485 IVT-treated patients at the Helsinki University Central Hospital was classified according to the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) criteria...

BACKGROUND: It is a well-known fact that very few patients of stroke arrive at the hospital within the window period of thrombolysis. Even among those who do, not all receive thrombolytic therapy. OBJECTIVE: The objectives of this study were to determine the proportion of early arrival ischemic strokes (within 6 h of stroke onset) in our hospital and to evaluate the causes of nonadministration of intravenous and/or intraarterial thrombolysis in them. MATERIALS AND METHODS: Data of all early arrival acute stroke patients between January 2010 and January 2015 were included...
