BACKGROUND AND PURPOSE: Patients with ischemic stroke and large vessel occlusion are assumed to benefit from endovascular therapy (ET) independent of the symptom onset-to-treatment time (OTT) if they present with a mismatch of diffusion- and perfusion-weighted imaging (DWI-PWI mismatch). We aimed at studying the influence of OTT on clinical outcome in these patients. METHODS: Retrospective database review in a tertiary care university hospital. All patients presented with proximal vessel occlusion of the anterior circulation and DWI-PWI mismatch...

BACKGROUND: Intracranial hemorrhage is a major complication of endovascular treatment in patients with acute ischemic stroke. Controlled clinical trials reported varied incidences of intracranial hemorrhage after endovascular treatment. This meta-analysis aimed to estimate whether endovascular treatment, compared with medical treatment, increases the risk of intracranial hemorrhage in patients with acute ischemic stroke. METHODS: The current publications on endovascular treatment for acute ischemic stroke were systematically reviewed...

BACKGROUND AND PURPOSE: The Interventional Management of Stroke (IMS) III trial was a randomized controlled trial designed to compare the effect of endovascular therapy after intravenous recombinant tissue plasminogen activator (i.v. rt-PA) as compared to i.v. rt-PA alone. The primary outcome was modified Rankin Scale at 90 days. Secondary outcomes included National Institutes of Health Stroke Scale (NIHSS), which was assessed repeatedly through 90 days. The objective of this analysis is to evaluate the treatment effect of endovascular therapy over time on NIHSS...

BACKGROUND AND PURPOSE: Stent retriever thrombectomy and manual aspiration thrombectomy (MAT) have each been shown to lead to high rates of recanalization as single-modality endovascular stroke therapy. We sought to describe the safety and efficacy of a multimodal approach combining these two techniques termed 'stent retriever-mediated manual aspiration thrombectomy' (SMAT) and compared them to MAT alone. METHODS: Retrospective review of a prospectively acquired acute endovascular stroke database...

Cervical artery dissection (CAD) is an important cause of stroke for young patients, accounting for 5-22% of strokes in patients <45 years of age, which presents not only a great burden to the stroke victims but also a financial burden to the family and society. Because CAD can lead to different clinical lesions, including neuropathy, acute ischemic stroke, and subarachnoid hemorrhage, and is an arterial dissection with a self-healing tendency, the treatment options depend on the clinical manifestations...

Background Predicting recanalization success for patients undergoing endovascular treatment for acute ischemic stroke is of significant interest. Studies have previously correlated the success of recanalization with the density of the clot. We evaluated clot density and its relationship to revascularization success and stroke etiology. Methods We conducted a retrospective review of 118 patients undergoing intra-arterial therapy for acute ischemic stroke. Mean and maximum thrombus density was measured by drawing a circular region of interest on an axial slice of a non-contrast computed tomography scan...

Optimal treatment of intracranial aneurysms (IAs) in elderly patients has not yet been well established. We have investigated the clinical and radiological outcomes and predictors of unfavorable outcome of IAs in elderly patients. Radiological and clinical data of 85 elderly patients from 2010 through 2015 were retrospectively reviewed. Significant differences between the groups were determined by a chi-square test. Regression analysis was performed to identify the predictors of unfavorable outcome. Among the 85 patients with IAs, the number of patients with >7mm size aneurysm (p=0...

BACKGROUND AND PURPOSE: Increasing thrombus length (TL) impedes recanalization after intravenous (IV) thrombolysis. We sought to determine whether the clinical benefit of aspiration thrombectomy relative to IV r-tPA (recombinant tissue-type plasminogen activator) may be greater at longer TL. METHODS: THERAPY was a randomized trial of aspiration thrombectomy plus IV r-tPA versus IV r-tPA alone in large-vessel stroke patients with prospective TL measurement ≥8 mm...

OBJECTIVES: This study aimed to examine prognosis and causes of death in hemodialysis (HD) patients with critical limb ischemia (CLI) after endovascular therapy (EVT). BACKGROUND: EVT is becoming a first-line treatment in patients with CLI. Nonetheless, only a few studies have examined prognosis and its predictors in HD patients with CLI undergoing EVT, who are known to be at high-risk. Moreover, causes of death in this population are not clarified to date. METHODS: We examined 175 consecutive patients who underwent EVT for CLI between March 2009 and March 2014...

In a meta-analysis of individual patient data from 5 randomized controlled trials, endovascular treatment (EVT) mainly using a stent retriever achieved successful recanalization in 71.1% of patients suffering from acute stroke due to anterior circulation large artery occlusion (LAO). However, EVT still failed in 28.9% of LAO cases in those 5 successful trials. Stent retriever failure may occur due to anatomical challenges (e.g., a tortuous arterial tree from the aortic arch to a target occlusion site), a large quantity of clots, tandem occlusion, clot characteristics (fresh versus organized clots), different pathomechanisms (embolic versus non-embolic occlusion), etc...

Rationale Mechanical thrombectomy with a stent retriever is now the standard of care in anterior circulation ischemic stroke caused by large vessel occlusion. New techniques for mechanical thrombectomy, such as contact aspiration, appear promising to increase reperfusion status and improve clinical outcome. Aim We aim at ascertaining whether contact aspiration is more efficient than the stent retriever as a first-line endovascular procedure. Sample size estimates With a two-sided test (alpha = 5%, power = 90%) and an anticipated rate of spontaneous recanalization and catheterization failures of 15%, we estimate that a sample size of 380 patients will be necessary to detect an absolute difference of 15% in primary outcome (superiority design)...

The occurrence of a stroke in children and adolescents constitutes a rare, critical event that is associated with substantial morbidity and mortality. In addition to the individual suffering for the young patient and the medical burden for the affected family, a stroke is also associated with high follow-up costs for the health system because of the necessary long-term rehabilitative treatment. Establishing an early and prompt diagnosis is of great therapeutic importance. Because of the rarity of the illness and the plethora of clinical manifestations, diagnosis is often delayed...
