BACKGROUND: Acute ischemic stroke (AIS) is a common neurological event that causes varying degrees of disability. AIS outcome varies considerably, from complete recovery to complete loss of tissue and function. This diversity is partly explained by the compensatory ability of the collateral circulation and the ensuing cerebral flow grade. The collateral flow to the anterior circulation largely supplies the cortical areas. The deep brain tissue is supplied by penetrating arteries and has little or no collateral supply...

BACKGROUND AND PURPOSE: Endovascular therapy in addition to standard care (EVT+SC) has been demonstrated to be more effective than SC in acute ischemic large vessel occlusion stroke. Our aim was to determine the cost-effectiveness of EVT+SC depending on patients' initial National Institutes of Health Stroke Scale (NIHSS) score, time from symptom onset, Alberta Stroke Program Early CT Score (ASPECTS), and occlusion location. METHODS: A decision model based on Markov simulations estimated lifetime costs and quality-adjusted life years (QALYs) associated with both strategies applied in a US setting...

OBJECTIVE: The Pragmatic Ischaemic Thrombectomy Evaluation (PISTE) trial was a multicentre, randomised, controlled clinical trial comparing intravenous thrombolysis (IVT) alone with IVT and adjunctive intra-arterial mechanical thrombectomy (MT) in patients who had acute ischaemic stroke with large artery occlusive anterior circulation stroke confirmed on CT angiography (CTA). DESIGN: Eligible patients had IVT started within 4.5 hours of stroke symptom onset. Those randomised to additional MT underwent thrombectomy using any Conformité Européene (CE)-marked device, with target interval times for IVT start to arterial puncture of <90 min...

PURPOSE: Mechanical thrombectomy using a Solitaire stent has been associated with a high recanalization rate and favorable clinical outcome in intra-arterial thrombolysis. To achieve a higher recanalization rate for mechanical Solitaire thrombectomy, we used an intra-arterial low-dose booster tirofiban injection into the occluded segment after stent deployment. We report the safety and recanalization rates for mechanical Solitaire thrombectomy with a low-dose booster tirofiban injection...

BACKGROUND AND PURPOSE: Intra-arterial treatment by means of retrievable stents has been proven safe and effective. In MR CLEAN (Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands), the choice of the type of thrombectomy device was left to the discretion of the interventionist. The aim of this study was to explore the differences in functional outcome, neurological recovery, reperfusion, extent of infarction, and adverse events according to stent type and make...

Importance: After the many positive results in thrombectomy trials in ischemic stroke of the anterior circulation, the question arises whether these positive results also apply to the patient with basilar artery occlusion (BAO). Objective: To report up-to-date outcome data of intra-arterial (IA) treatment in patients with BAO and to evaluate the influence of collateral circulation on outcome. Design, Setting, and Participants: Single-center retrospective case series of 38 consecutive patients with BAO who underwent IA treatment between 2006 and 2015 at a comprehensive stroke center...

BACKGROUND: Patient selection for endovascular revascularization treatment (ERT) in acute ischemic stroke depends on the expected benefit-risk ratio. As rapid revascularization is a major determinant of good functional outcome, we aimed to identify its predictors after ERT. METHODS: Consecutive stroke patients from a single stroke center with distal internal carotid artery-, proximal middle cerebral artery- or T-occlusions treated with ERT were retrospectively selected...

Acute ischemic stroke is responsible for around 80% of all strokes and is a leading cause of disability and death globally. There are two potential treatment strategies: restoring blood flow (reperfusion) and preventing cellular injury (neuroprotection). As yet, all the successful trials have involved reperfusion with numerous failures of neuroprotectants. There are two proven reperfusion strategies. Intravenous thrombolysis with alteplase was first demonstrated to reduce disability with publication of the National Institute of Neurological Disorders and Stroke tissue plasminogen activator trial in 1995...

BACKGROUND: Successful reopening of epicardial coronary artery does not always mean optimal myocardial reperfusion in a sizable portion of patients, mostly because of no-reflow phenomenon. OBJECTIVES: We investigated whether local injection of adrenaline ± verapamil in the distal coronary bed is more effective than their intracoronary (IC) injection through the guiding catheter in the treatment of no-reflow phenomenon following percutaneous coronary intervention (PCI)...

Cerebral venous sinus thrombosis (CVST) can have devastating results, with mortality reported in 44% of cases. No randomized trials exist in order to define what qualifies as failure of conservative therapy, and there is no specific intervention to date which is considered safe and effective. Case series suggest that thrombolysis infusion is safer than thrombectomy, but methods of administration, dose, and duration of therapy tend to vary widely. We present three consecutive CVST patients treated with heparin who suffered both clinical and radiographic deterioration, and went on to have endovascular therapy...

OBJECTIVES: Thrombolysis has been reported to be suboptimal in occluded vein grafts and cryopreserved allografts, and there are no data on the efficacy of thrombolysis in occluded cold stored venous allografts. The aim was to evaluate early outcomes, secondary patency and limb salvage rates of thrombolysed cold stored venous allograft bypasses and to compare the outcomes with thrombolysis of autologous bypasses. METHODS: This was a single center study of consecutive patients with acute and non-acute limb ischemia between September 1, 2000, and January 1, 2014, with occlusion of cold stored venous allografts, and between January 1, 2012, and January 1, 2014, with occlusion of autologous bypass who received intra-arterial thrombolytic therapy...

INTRODUCTION: Acute arterial thromboembolism to the renal arteries can be treated promptly by local thrombolysis, conventional surgical thrombectomy, or by anticoagulation. METHODS: We report a patient who presented with acute loin pain as a result of atrial fibrillation related thrombo-embolism to right renal artery supplying his horseshoe kidney. He was already on warfarin treatment with INR of 1.7 and had acute bleeding from malignant peptic ulcer disease, so thrombolysis was contraindicated...

OBJECTIVES: Hepatic artery thrombosis (HAT) is a serious complication after living-donor liver transplantation (LDLT) leading to patient death in the absence of revascularization. With the recent advances in interventional radiology, interventional endovascular techniques have been used as alternative therapeutic options for HAT. This study evaluates the feasibility and clinical outcomes of endovascular treatment for HAT after LDLT. METHODS: The medical records of 120 patients who underwent adult-to-adult LDLT between February 2002 and February 2015 in our hospital were retrospectively reviewed to evaluate the frequency of HAT and outcomes of endovascular treatment...

BACKGROUND: Although intravenous thrombolysis is the Food and Drug Administration-approved treatment for acute ischemic stroke (AIS) within 3 h, combined intravenous and intra-arterial thrombolysis with endovascular techniques may be able to extend this traditional time window. CASE DESCRIPTION: We present the clinical evolution of a 45-year-old male presenting with acute left hemiparesis. Magnetic resonance imaging revealed a small diffusion restriction at the right basal ganglia with perfusion compromise in the entire right middle cerebral artery (MCA) territory...

BACKGROUND: Recently, a mobile stroke unit (MSU) was shown to facilitate acute stroke treatment directly at the emergency site. The neuroradiological expertise of the MSU is improved by its ability to detect early ischemic damage via automatic electronic (e) evaluation of CT scans using a novel software program that calculates the electronic Alberta Stroke Program Early CT Score (e-ASPECTS). METHODS: The feasibility of integrating e-ASPECTS into an ambulance was examined, and the clinical integration and utility of the software in 15 consecutive cases evaluated...

This study sought to determine whether the permeability related parameter K(trans), derived from computed tomography perfusion (CTP) imaging, can predict hemorrhagic transformation (HT) in patients with acute ischemic stroke who receive intra-arterial thrombolysis. Data from patients meeting the criterion were examined. CTP was performed and K(trans) maps were used to assess the permeability values in HT and non-HT regions. A receiver operating characteristic (ROC) curve was calculated, showing the sensitivity and specificity of K(trans) for predicting HT risk...
