REVIVE SE (REVIVE) is a closed-ended, self-expanding stent retriever used in the RIVER JAPAN study. We present our early experience with REVIVE for revascularization of acute ischemic stroke (AIS) in patients who have failed or are ineligible for intravenous recombinant tissue plasminogen activator treatment. This prospective, single-arm, non-randomized, multicenter registry study followed up patients undergoing mechanical thrombectomy with REVIVE for 90 days. The primary endpoint was a post-procedure Thrombolysis in Cerebral Infarction (TICI) score ≥2a...

BACKGROUND: Randomized controlled trials (RCTs) have compared mechanical endovascular therapy (MET) in addition to intravenous tissue plasminogen activator (IVtPA) to IVtPA alone for the management of acute ischemic stroke (AIS). Direct comparative studies between individual METs are not available. In lieu of head-to-head randomized control trials, we performed an adjusted indirect treatment comparison (ITC) meta-analysis to assess the comparative efficacy and safety of different METs, Solitaire+IVtPA and Penumbra+IVtPA in AIS patients...

PURPOSE: A complicated course of the femoral route for neurointervention can prevent approaching the target. Thus, we determined whether transcervical access in the hybrid angiosuite is applicable and beneficial in real practice. METHODS: From January 2014 to March 2017, this approach was used in 17 of 453 (3.75%) cases: 11 cerebral aneurysms (4 ruptured, 7 unruptured), 4 acute occlusions of the large cerebral artery, 1 proximal internal carotid artery (ICA) stenosis, and 1 direct carotid cavernous fistula (CCF)...

Acute thrombotic occlusions of the large vessels, such as internal carotid artery, arms and legs arteries, and intracranial vessels, frequently require multiple techniques such as selective thrombolysis, manual aspiration, and stent retrievers for mechanical thrombectomy with combination of the mentioned techniques. Because of the massive thrombotic burden associated with these conditions, the response to systemic intravenous thrombolysis is poor. We present a case of a successful massive thrombi aspiration in a single attempt using an 8Fr guide catheter with aspiration syringe, subsequent ipsilateral middle cerebral artery mechanical thrombectomy, and axillary artery clot disruption attempt in a patient with acute ischemic stroke, right arm critical ischemia, and persistent atrial fibrillation...

BACKGROUND: Ureteroarterial fistula (UAF) represents an uncommon complication after urological surgery; however, this is a well-documented condition in patients with predisposing risk factors. The aim of the present study is to report and analyze the endovascular management of a series of patients with UAF, treated in authors' hospital, and to report and analyze the same data concerning patients retrieved from a systematic literature review. METHODS: Authors conducted a retrospective analysis of prospectively collected data and a systematic literature review...

A 72-year-old male with diabetes and smoking as coronary risk factors was evaluated for chronic stable angina - Canadian Cardiovascular Society III - despite guideline directed medical treatment which revealed a diffuse, tortuous, calcified narrowing (90% stenosis) in left circumflex (LCx) coronary artery. After predilatation, a 3.0 - 2.5 × 60 mm BioMime Morph stent - long tapering stent (Sirolimus eluting stent, Meril life Sciences, India) - was tracked which failed and dislodged to right deep femoral artery during its pullback...

OBJECTIVES: The aim was to evaluate individualised treatment and long-term outcomes of endovascular treatment of Budd-Chiari syndrome (BCS) complicated by inferior vena cava (IVC) thrombosis. METHODS: Between April 2005 and December 2015, 108 consecutive patients with BCS complicated by IVC thrombosis underwent endovascular treatment. According to the type, size, extent, and degree of organisation of the thrombus, agitation thrombolysis (n = 7), agitation thrombolysis combined with retrieval stent filter (n = 5), pre-dilation (n = 32), retrieval stent filter (n = 56), or direct large balloon dilation (n = 8) was performed...

PURPOSE: Intra-arterial therapy of acute ischemic stroke has developed rapidly in recent years. Due to proven efficacy in randomized trials, stent retrievers were replacing first-generation thrombectomy devices and have been defined as method of choice. However, aspiration catheters or a combination of several techniques have shown promising rates of successful recanalizations. To create a basis for comparison of the new approaches according to real-world data, we determined the first pass recanalization rate of an evidence-based standard technique with the use of a stent retriever in combination with a balloon-guiding catheter...

OBJECTIVE: A new endovascular tool, the Liungman Guidewire Fixator, has been developed to simplify endovascular treatment in complex aortic aneurysms. The device has been extensively tested in bench models and animal trials. To verify the safety and functionality demonstrated in the porcine model, the device was tested in ten patients undergoing endovascular aortic repair (EVAR) or fenestrated endovascular aortic repair (f-EVAR) treatment for abdominal aortic aneurysm. METHODS: The Liungman Guidewire Fixator consists of a braided stent-like, cylindrical structure with conical ends and a central channel for a 0...

BACKGROUND AND OBJECTIVE: Acute ischemic stroke is a potentially devastating condition and leading cause of morbidity and mortality, affecting an estimated 800 000 people per year in the USA. The natural history of untreated or unrevascularized large vessel occlusions in acute stroke patients results in mortality rates approaching 30%, with only 25% achieving good neurologic outcomes at 90 days. Recently, data have demonstrated that early endovascular recanalization of large vessel occlusions results in better outcomes than medical therapy alone...

INTRODUCTION/PURPOSE: Mechanical thrombectomy (MT) for acute ischemic stroke (IS) can be performed also in patients on anticoagulation therapy (AT); however, sufficient and reliable data about safety and efficacy of MT are still missing. Thus, we aimed to compare these parameters between patients treated on AT and without AT. MATERIALS AND METHODS: All consecutive IS patients treated with MT using stent retrievers were included in the retrospective analysis. Neurological deficit was scored using National Institutes of Health Stroke Scale (NIHSS) and 90-day clinical outcome using modified Rankin scale with a score 0-2 for good outcome...
