Aim and hypothesis Using a new study design, we investigate whether next-generation mechanical thrombectomy devices improve clinical outcomes in ischemic stroke patients. We hypothesize that this new methodology is superior to intravenous tissue plasminogen activator therapy alone. Methods and design ERic Acute StrokE Recanalization is an investigator-initiated prospective single-arm, multicenter, controlled, open label study to compare the safety and effectiveness of a new recanalization device and distal access catheter in acute ischemic stroke patients with symptoms attributable to acute ischemic stroke and vessel occlusion of the internal cerebral artery or middle cerebral artery...

BACKGROUND: The average life expectancy is increasing worldwide, surpassing 80 years in some countries. Recently, mechanical thrombectomy (MT) using modern devices and techniques has led to improved clinical outcomes following acute ischemic stroke. However, thus far, it remains uncertain whether MT is effective in elderly patients aged over 80 years. METHODS: Between July 2013 and June 2016, 207 patients with acute ischemic stroke in the anterior circulation received MT at our center...

PURPOSE OF REVIEW: Recent randomized clinical trials have demonstrated strong efficacy of endovascular therapy (EVT) for acute ischemic stroke (AIS) from large vessel occlusions; in the USA alone, tens of thousands of patients annually may benefit. The impact of the type of anesthesia used during mechanical thrombectomy on patient outcomes remains controversial. This review discusses the current literature on the effects of anesthesia type on patient outcome following endovascular stroke therapy...

Stenting and balloon angioplasty, along with mechanical thrombectomy, have gained notability as adjunctive treatment options to intravenous tissue plasminogen activator (IV-tPA) for tandem internal carotid artery (ICA) and middle cerebral artery (MCA) occlusions (TIM occlusions). Acute ischemic strokes (AISs) secondary to TIM occlusions are associated with poor patient outcomes primarily due to low recanalization rates following intravenous thrombolysis, consequently prompting the need for more invasive recanalization efforts...

Endovascular mechanical thrombectomy for stroke patients with large vessel occlusion (LVO) in the anterior circulation has become the standard of care based on several major randomized clinical trials. The successful result reported by these trials constitutes what may be the largest achievement in the history of neurological sciences. However, most of these mechanical thrombectomy trials (except for the multicenter randomized clinical trial of endovascular treatment for acute ischemic stroke in the Netherlands, i...

Patients with in-hospital strokes (IHS) may be eligible for recanalization therapies. The objective of this study is to compare outcomes in patients with IHS and community-onset strokes (COS) treated by recanalization therapy. We analysed data prospectively collected in consecutive patients treated by thrombolysis, thrombectomy, or both for cerebral ischemia at the Lille University Hospital. We compared four outcomes measures at 3 months in patients with IHS and COS: (1) modified Rankin scale (mRS) 0-1, (2) mRS 0-2, (3) death, and (4) symptomatic intracranial haemorrhage (ECASS 2 definition)...

BACKGROUND: Over half of patients who receive intravenous tissue plasminogen activator for middle cerebral artery division (MCA-M2) occlusion do not recanalize, leaving a large percentage of patients who may need mechanical thrombectomy (MT). However, the outcomes of MT for M2 occlusion have not been well characterized. OBJECTIVE: To determine if MT of M2 occlusion is as safe and efficacious as current standard-of-care MT for M1 occlusions. METHODS: With institutional review board approval, we retrospectively reviewed records of 212 patients undergoing MT for isolated MCA M1 or M2 occlusions during a 36-month period (Sept 2013 to Sept 2016) at two centres...

Recent clinical trials demonstrated that mechanical thrombectomy (MT) using second-generation endovascular devices has beneficial effects in acute ischemic stroke (AIS) due to large vessel occlusion (LVO). However, it remains controversial if intravenous thrombolysis (IVT) prior to MT is superior compared to direct mechanical thrombectomy (DMT). The aims of this study were to compare short and long-term outcomes between IVT + MT and DMT patients. We prospectively recruited AIS patients with LVO in the anterior or posterior circulation eligible for MT with and without prior IVT...

BACKGROUND AND PURPOSE: The clinical benefit of endovascular stroke therapy has been demonstrated in several prospective randomized trials. However, in a relevant percentage of patients, mechanical thrombectomy bears the risk of causing new infarction in initially unaffected vascular territories through thrombus fragmentation and migration of clot debris. The goal of this study was to evaluate the use of the balloon guide catheter (BGC) to effectively achieve flow arrest and thrombus aspiration during the intervention to avoid distal embolization...

Intra-arterial mechanical thrombectomy (IAMT) treatments for ischemic stroke have higher recanalization rate, longer treatment time window and lower risk of symptomatic intracerebral hemorrhage (sICH). However, distal embolization may occur because of loose fragments produced during maceration and engagement. The naturally coagulated thrombus is fragile and has poor binding with thrombectomy device. Improvement of thrombus-device binding can reduce fragments breaking loose during wire pull and enhance protein crosslinking in the thrombus that can increase fragmentation resistance...

OBJECTIVE: There are limited data evaluating the effect of post mechanical thrombectomy (MT) blood pressure (BP) levels on early outcomes of patients with large vessel occlusions (LVO). We sought to investigate the association of BP course following MT with early outcomes in LVO. METHODS: Consecutive patients with LVO treated with MT during a 3-year period were evaluated. Hourly systolic BP (SBP) and diastolic BP (DBP) values were recorded for 24 hours following MT and maximum SBP and DBP levels were identified...

Intracardiac thrombosis (ICT) and pulmonary thromboembolism (PE) after cardiopulmonary bypass (CPB) are life-threatening events, but pathological mechanisms are not yet well defined. The aim of this review is to provide an update of case literature of a postbypass hypercoagulable state. Case commonalities among 48 ICT/PE events included congestive heart failure (50%), platelet transfusion (37.5%), CPB duration greater than 3 hours (37.5%), and aortic injury (27.1%). Preexisting thrombophilia was rarely reported, and 16...

BACKGROUND AND PURPOSE: A new generation of carotid artery stents that uses a second micromesh layer to reduce embolic events during carotid artery stenting has recently been introduced. The purpose of this study was to compare acute occlusion rates of these new dual-layer stents with those of single-layer stents in the setting of emergency carotid artery stenting with intracranial mechanical thrombectomy in acute ischemic stroke. METHODS: Consecutive patients with acute tandem (intra- and extracranial) lesions of the anterior circulation who were endovascularly treated at our institution were identified from our registry of neuroendovascular interventions...

We report a patient with an important scenario that may arise in the management of an acute ischemic stroke: the need for a repeated mechanical thrombectomy in the same intracranial artery segment. The patient had a history of atrial fibrillation and a mechanical mitral valve replacement. In her first stroke, she had an occlusion of the proximal segment of the right middle cerebral artery; 58 days later, she presented with an occlusion in the same segment of that cerebral artery. In both instances, the thrombus was extracted by a stent retriever with good clinical and radiographic results...
