Safety and Functional Outcome of Thrombolysis in Dissection-Related Ischemic Stroke: A Meta-Analysis of Individual Patient Data

The safety and efficacy of thrombolysis in cervical artery dissection (CAD) are controversial. The aim of this meta-analysis was to pool all individual patient data and provide a valid estimate of safety and outcome of thrombolysis in CAD.

Impact of obesity on stroke outcome after intravenous thrombolysis

Obesity is an established risk factor for stroke and has reached epidemic proportions. However, its impact on intravenous thrombolysis applied for acute ischemic stroke is not well known. We aimed to compare the clinical outcome and safety after intravenous thrombolysis in obese (body mass index ≥30 kg/m²) and nonobese (body mass index <30 kg/m²) patients with ischemic stroke.

Traumatic subarachnoid hemorrhage, basal ganglia hematoma and ischemic stroke caused by a torn lenticulostriate artery

Subarachnoid hemorrhage (SAH), basal ganglia hematoma (BGH) and ischemic stroke are common diseases with diverging therapies. The simultaneous occurrence of these diseases is rare and complicates the therapy. We report the case of a 30-year-old man with a ruptured lenticulostriate artery after traumatic brain injury that caused the combination of SAH, BGH and ischemic stroke and subsequent cerebral vasospasm. This rupture mimicked the pathophysiology and imaging appearance of aneurysmal SAH. The site of rupture was not secured by any treatment; however, hyperdynamic therapy and percutaneous transluminal angioplasty were feasible in this setting to prevent additional delayed neurological deficit.

Endovascular Therapy of 623 Patients With Anterior Circulation Stroke

Endovascular therapy of acute ischemic stroke has been shown to be beneficial for selected patients. The purpose of this study is to determine predictors of outcome in a large cohort of patients treated with intra-arterial thrombolysis, mechanical revascularization techniques, or both.

Impact of Thrombolysis on Stroke Outcome at 12 Months in a Population: The Bern Stroke Project

Thrombolysis improves outcome of patients with acute ischemic stroke, but it is unknown whether thrombolysis has a measurable effect on long-term outcome in a defined population.

Copeptin and risk stratification in patients with ischemic stroke and transient ischemic attack: The CoRisk Study

RATIONALE: Copeptin independently predicts functional outcome and mortality at 90 days and one-year after ischemic stroke. In patients with transient ischemic attack, elevated copeptin values indicate an increased risk of further cerebrovascular events. AIMS: The Copeptin Risk Stratification (CoRisk) study aims to validate the predictive value of copeptin in patients with ischemic stroke and transient ischemic attack. In patients with ischemic stroke, the CoRisk study aims to further explore the effect of treatment (i.e. thrombolysis) on the predictive value of copeptin. DESIGN: Prospective observational multicenter study analyzing three groups of patients, i.e. patients with ischemic stroke treated with and without thrombolysis and patients with transient ischemic attack. OUTCOMES: Primary end-point: In patients with ischemic stroke, the primary end-point includes disability (modified Rankin scale from 3 to 5) and mortality (modified Rankin scale 6) at three-months after stroke. In patients with transient ischemic attack, the primary end-point is a recurrent ischemic cerebrovascular event (i.e. ischemic stroke or recurrent transient ischemic attack). Secondary end-point: In patients with ischemic stroke, the secondary end-points include in-house complications (i.e. symptomatic intracerebral hemorrhage, malignant edema, aspiration pneumonia or seizures during hospitalization, and in-house mortality).

Copeptin adds prognostic information after ischemic stroke: Results from the CoRisk study

To evaluate and validate the incremental value of copeptin in the prediction of outcome and complications as compared with established clinical variables.

Treatment of acute ischaemic stroke with thrombolysis or thrombectomy in patients receiving anti-thrombotic treatment

Systemic thrombolysis with alteplase is the only approved medical treatment for patients with acute ischaemic stroke. Thrombectomy is also increasingly used to treat proximal occlusions of the cerebral arteries, but has not shown superiority over systemic thrombolysis with alteplase. Many patients with acute ischaemic stroke are pretreated with antiplatelet or anticoagulant drugs, which can increase the bleeding risk of thrombolysis or thrombectomy. Pretreatment with aspirin monotherapy increases the bleeding risk of alteplase in both observational and randomised trials with no effect on clinical outcome, and the risk of intracerebral haemorrhage is increased with the combination of aspirin and clopidogrel. Antiplatelet drugs should not be given in the first 24 h after alteplase treatment. Data from pooled randomised trials and a large observational study show that thrombolysis can probably be done safely in patients given vitamin-K antagonists if the international normalised ratio is less than 1·7, although bleeding risk is slightly raised. Almost no data are available for the safety of alteplase in patients with atrial fibrillation who have been given novel oral anticoagulants (NOAC) for stroke prevention. Some coagulation parameters could help to identify patients treated with NOAC who might be eligible for thrombolysis. Thrombectomy can be done in patients given antiplatelets and probably in those given anticoagulants; however, conclusions about anticoagulants are based on findings from observational studies with small patient numbers.
