BACKGROUND: Intravenous thrombolysis (IVT) and endovascular therapy (EVT) were proven safe and effective for anterior circulation proximal occlusions. However, the most appropriate recanalization strategy in patients with acute basilar artery occlusion (BAO) is still controversial. This study aimed to assess outcomes of patients with BAO at an academic stroke center in Brazil. METHODS: This is a retrospective analysis of consecutive patients with BAO from a prospective stroke registry at Ribeirão Preto Medical School...

BACKGROUND AND PURPOSE: Prediction of underlying intracranial atherosclerotic stenosis before endovascular therapy might be helpful for appropriate therapeutic planning in patients with acute ischemic stroke. This study aimed to compare the characteristics and treatment outcomes in patients with acute basilar artery occlusion relative to the existence or nonexistence of underlying intracranial atherosclerotic stenosis. MATERIALS AND METHODS: Sixty-two patients with acute basilar artery occlusion underwent multimodal endovascular therapy...

Long-awaited positive trial data have shown the efficacy of endovascular treatment in patients with ischemic stroke who arrive at the hospital within the first 6 hours with large-vessel occlusion of the anterior circulation. With the introduction of stent retrievers (SRs) for mechanical thrombectomy, efficient and safe large-artery recanalization treatment can be achieved. However, sometimes there are patients who do not attain complete flow restoration following attempts with traditional maneuvers. The authors present the case of a 57-year-old man with acute ischemic stroke due to an M1 embolus that extended into both M2 trunks...

PURPOSE: Most recent guidelines recommend the use of stent retriever devices in endovascular treatment of acute ischemic stroke with large vessel occlusion (LVO). Recently published data reported convincing results with thromboaspiration devices such as the Penumbra System (Penumbra, Alameda, CA, USA) combined with supple reperfusion catheters by using the ADAPT (A Direct Aspiration First-Pass Thrombectomy) technique. The aim of this study was to report our initial experience with the 3MAX (3...

REVIEW
Richard R Heuser
Even though cardiovascular disease (CVD) is still the leading cause of death in the United States, stroke is the second leading of global cause of death behind CVD . In the 21st Century, less than 40% of overall stroke patients are discharged to home and almost 25% of Medicare beneficiaries do not survive 90days. In spite of the fact that tissue plasminogen activator (TPA) has been approved for stroke care for 20years, only .75% of annual strokes are actually treated with intravenous (IV) TPA. Similar to how interventional cardiologists evolved from IV to catheter mechanical treatment for acute myocardial infarctions (AMI) over 30years ago, over the last few years, neurointerventionists now perform endovascular stroke therapy in many of these patients using stent retrievers...

BACKGROUND AND PURPOSE: The Embolus Retriever with Interlinked Cages (ERIC) device is a novel stent retriever for mechanical thrombectomy. It consists of interlinked cages and could improve procedural benchmarks and clinical outcome compared with classic stent retrievers. This study compares the rates of recanalization, favorable clinical outcome, procedural adverse events, and benchmarks between the ERIC device and classic stent retrievers. MATERIALS AND METHODS: From 545 patients treated with thrombectomy between 2012 and 2015, 316 patients were included...

Dong-Hun Kang, Jaechan Park
Intravenous recombinant tissue plasminogen activator had been the only approved treatment for acute ischemic stroke since its approval in 1995. However, the restrictive time window, numerous contraindications, and its low recanalization rate were all limitations of this modality. Under those circumstances, endovascular stroke therapy went through a great evolution during the past two decades of intravenous thrombolysis. The results of the 2013 randomized trials for endovascular stroke therapy were neutral, although they were limited by insufficient imaging screening at enrollment, early-generation devices with less efficacy, and treatment delays...

Introduction The efficacy of the endovascular treatment of acute ischemic stroke has been substantiated by several recent randomized clinical trials. While intra-arterial therapy has significantly evolved in recent years, anatomic cerebrovascular variants and disease burden can present challenges to timely recanalization. We present the first reported case of anterior-to-posterior mechanical clot retrieval with use of a stent retriever. Case description A 53-year-old man presented with basilar artery thrombosis...

BACKGROUND AND PURPOSE: In the treatment of acute thromboembolic stroke, the effectiveness and success of thrombus removal when using stent retrievers is variable. In this study, we analyzed the correlation of thrombectomy maneuver count with a good clinical outcome and recanalization success. MATERIALS AND METHODS: One hundred and four patients with acute occlusion of the middle cerebral artery or the terminal internal carotid artery who were treated with thrombectomy were included in this retrospective study...

BACKGROUND AND PURPOSE: General anesthesia during endovascular treatment of acute ischemic stroke may have an adverse effect on outcome compared with conscious sedation. The aim of this study was to examine the impact of the type of anesthesia on the outcome of patients with acute ischemic stroke treated with the Solitaire stent retriever, accounting for confounding factors. MATERIALS AND METHODS: Four-hundred one patients with consecutive acute anterior circulation stroke treated with a Solitaire stent retriever were included in this prospective analysis...

Mechanical thrombectomy with stent retrievers is now the reference therapy for acute ischemic stroke (AIS) in the anterior circulation in association with thrombolysis. We conducted an extensive systematic review and meta-analysis to evaluate the clinical and angiographic outcomes of stent-retriever thrombectomy in patients with acute anterior circulation stroke. Available literature published to date on observational studies and three randomized trials (MR CLEAN, ESCAPE, and EXTEND-IA) involving the stent-retriever device were reviewed...

The efficacy of mechanical thrombectomy with stent retrievers for emergent large vessel occlusion has been proved by randomized trials. Mechanical thrombectomy is increasingly being adopted in Japan since stent retrievers were first approved in 2014. An urgent clinical task is to offer structured systems of care to provide this treatment in a timely fashion to all patients with emergent large vessel occlusion. Treatment with flow-diverting stents is currently a preferred treatment option worldwide for large and giant unruptured aneurysms...

BACKGROUND AND PURPOSE: A direct aspiration first pass technique (ADAPT) has been reported to be fast, safe, and effective for the treatment of acute ischemic stroke. The aim of this study is to determine the preoperative factors that affect success of the aspiration component of the technique in ischemic stroke patients with large vessel occlusion in the anterior circulation. METHODS: We enrolled all 347 consecutive patients with anterior circulation acute ischemic stroke admitted for mechanical thrombectomy at our institution from August 2013 to October 2015 and treated by ADAPT for the endovascular treatment of stroke...

BACKGROUND AND PURPOSE: Symptomatic intracranial hemorrhage (SICH) pose a major safety concern for endovascular treatment of acute ischemic stroke. This study aimed to evaluate the risk and related factors of SICH after endovascular treatment in a real-world practice. METHODS: Patients with stroke treated with stent-like retrievers for recanalizing a blocked artery in anterior circulation were enrolled from 21 stroke centers in China. Intracranial hemorrhage was classified as symptomatic and asymptomatic ones according to Heidelberg Bleeding Classification...

OBJECTIVE In vivo and in vitro studies have demonstrated histological evidence of iatrogenic endothelial injury after stent retriever thrombectomy. However, noncontrast vessel wall (VW)-MRI is insufficient to demonstrate vessel injury. Authors of this study prospectively evaluated iatrogenic endothelial damage after stent retriever thrombectomy in humans by utilizing high-resolution contrast-enhanced VW-MRI. Characterization of VW-MRI changes in vessels subject to mechanical injury from thrombectomy may allow better understanding of the biological effects of this intervention...
