BACKGROUND: Endovascular therapy (EVT) with stent retrievers in addition to i.v. thrombolysis (IVT) has proven effective in acute stroke patients with middle cerebral artery (MCA, M1 segment) and distal internal carotid artery (ICA) occlusion. Limited data exist concerning acute cervical ICA occlusion, either alone or in combination with intracranial ICA occlusion (tandem occlusion). Therefore we analyzed outcome and treatment effects in stroke associated with cervical ICA occlusion, with specific focus on the impact of intracranial ICA or M1 patency...

BACKGROUND: Stroke patients who have cerebral micro bleeds (CMBs) could be potentially at a greater risk for symptomatic intracerebral hemorrhage (sICH) than those patients without CMBs. The aim of our study was to investigate whether the presence and burden of CMBs are associated with post IVT sICH. METHODS: In this multicenter study, consecutive patients treated with intravenous tissue plasminogen activator were prospectively identified and analyzed. Patients without magnetic resonance imaging (MRI) within 24 hours of treatment were excluded...

This study aimed to assess the risk of intracerebral hemorrhage (ICH) after tissue-type plasminogen activator (tPA) treatment in rivaroxaban compared with warfarin-pretreated male Wistar rat brain after ischemia in relation to activation profiles of protease-activated receptor-1, -2, -3, and -4 (PAR-1, -2, -3, and -4). After pretreatment with warfarin (0.2 mg/kg/day), low-dose rivaroxaban (60 mg/kg/day), high-dose rivaroxaban (120 mg/kg/day), or vehicle for 14 days, transient middle cerebral artery occlusion was induced for 90 min, followed by reperfusion with tPA (10 mg/kg/10 ml)...

BACKGROUND AND PURPOSE: Early neurological deterioration (END) after anterior circulation stroke is strongly associated with poor outcome. Apart from straightforward causes, such as intracerebral hemorrhage and malignant edema, the mechanism of END occurring after intravenous thrombolysis remains unclear in most instances. We tested the hypothesis that unexplained END is associated with thrombus extension. METHODS: From our database of consecutively thrombolysed patients, we identified anterior circulation stroke patients who had both admission and 24-hour T2* magnetic resonance imaging, visible occlusion on admission magnetic resonance angiography and no recanalization on 24-hour magnetic resonance angiography...

Early risk stratification of mortality and dependence is important for guiding medical decision-making in stroke care. The study aim is to evaluate whether there are any differences between risk factors for in-hospital mortality and dependence at discharge in patients with first-episode ischemic stroke in the middle cerebral artery (MCA) receiving intravenous thrombolysis (IVT) treatment. The study comprised a single-center cohort of patients admitted consecutively for first-episode MCA ischemic stroke. A logistic regression analysis was performed to determine the variables associated with in-hospital mortality and dependence at discharge...

It is still controversial whether pre-existing cerebral microbleeds (CMBs) increase the risks of intracranial hemorrhage (ICH) and poor functional outcome (PFO) in acute ischemic stroke (AIS) patients treated with intravenous thrombolysis (IVT). Therefore, we performed a systematic review and meta-analysis to determine the impact of CMBs on ICH and PFO of AIS patients with IVT. We searched PubMed, EMBASE and Web of Science from inception to August 3, 2016, with language restriction in English. We included studies that reported the relationship between CMBs and ICH or PFO after thrombolysis...

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...

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...

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 AND PURPOSE: We performed a meta-analysis to assess whether leukoaraiosis on brain computed tomographic scans of acute ischemic stroke patients treated with intravenous thrombolysis is associated with an increased risk of symptomatic intracerebral hemorrhage (sICH) or poor functional outcome at 3 to 6 months after stroke, or both. METHODS: We searched PubMed and pooled relevant data in meta-analyses using random effects models. Using odds ratios (OR), we quantified the strength of association between the presence and severity of leukoaraiosis and post-thrombolysis sICH or 3- to 6-month modified Rankin Score >2...

BACKGROUND AND PURPOSE: The ALIAS (Albumin in Acute Ischemic Stroke) part 1 and 2 trials evaluated whether 25% human serum albumin improves clinical outcomes after acute ischemic stroke above and beyond standard of care using similar protocols. The part 1 trial ended prematurely because of safety concerns, and the part 2 trial terminated early because of futility of finding a statistically significant effect of albumin over saline (control) administration. We combine the subject-level data of the part 1 and 2 trials to reevaluate the efficacy and safety outcomes with the larger sample size...

BACKGROUND: Symptomatic intracerebral hemorrhage (sICH) is one of the most feared complications after administration of intravenous recombinant tissue plasminogen activator (IV rtPA). The aim of this study was to determine correlations between hemorrhage volume (HV) after IV rtPA treatment and risk factors for sICH. METHODS: We analyzed 318 patients from the stroke registries of 4 hospitals in Korea. We confirmed hemorrhage by computed tomography (CT) or magnetic resonance imaging within 36 hours...

BACKGROUND: The first specific antidote for non-vitamin K antagonist oral anticoagulants (NOAC) has recently been approved. NOAC antidotes will allow specific treatment for 2 hitherto problematic patient groups: patients with oral anticoagulant therapy (OAT)-associated intracerebral hemorrhage (ICH) and maybe also thrombolysis candidates presenting on oral anticoagulation (OAT). We aimed to estimate the frequency of these events and hence the quantitative demand of antidote doses on a stroke unit...

BACKGROUND AND PURPOSE: Remote parenchymal hemorrhage (rPH) after intravenous thrombolysis with recombinant tissue-type plasminogen activator may be associated with cerebral amyloid angiopathy, although supportive data are limited. We aimed to investigate risk factors of rPH after intravenous thrombolysis with recombinant tissue-type plasminogen activator. METHODS: This is an observational study of patients with ischemic stroke who were treated with intravenous thrombolysis with recombinant tissue-type plasminogen activator and were included in a multicenter prospective registry...

Calcium is an essential element for life and has cerebroprotective property in stroke patients. Low serum calcium levels were found to be related to large hematoma volumes in intracerebral hemorrhagic patients and hemorrhagic transformation in ischemic stroke patients after thrombolysis. However, their impact on hemorrhage-prone small vessel disease represented by cerebral microbleeds (CMBs) is uncertain. We aim to investigate whether low serum calcium levels are associated with presence and location of CMBs...

BACKGROUND: The Preventive Antibiotics in Stroke Study (PASS), a randomized open-label masked endpoint trial, showed that preventive ceftriaxone did not improve functional outcome at 3 months in patients with acute stroke (adjusted common OR 0.95; 95% CI 0.82-1.09). Post-hoc analyses showed that among patients who received intravenous thrombolysis (IVT), patients who received ceftriaxone had a significantly better outcome as compared with the control group. This study aimed to gain more insight into the characteristics of these patients...

BACKGROUND: Intravenous thrombolysis can improve neurological outcomes after acute ischemic stroke (AIS), but hemorrhagic transformation (HT) of the infarct remains a risk. Current definitions for symptomatic intracerebral hemorrhage (ICH) all entail that there be some degree of associated neurological deterioration. However, early deleterious effects of secondary ICH might also be manifested as reduced neurological improvement. This study aims to investigate whether there are any independent associations between different radiological subtypes of HT and the degree of neurological improvement 24 hours after thrombolysis...

BACKGROUND AND PURPOSE: Both intracerebral hemorrhage (ICH) and brain edema have been attributed to reperfusion after intravenous thrombolysis. We explored the interaction of recanalization and core size for imaging outcomes (ICH and vasogenic brain edema). METHODS: In patients with anterior circulation occlusion given intravenous thrombolysis <4.5 hours and imaged with computed tomographic (CT) perfusion and CT angiography, we defined volumes of core (relative delay time >2 s and relative cerebral blood flow <40%) and penumbra (relative delay time >2 s)...
