Clinical evidence of the potential treatment benefit mechanical thrombectomy for posterior circulation distal, medium vessel occlusion (DMVO) is sparse.To investigate frequency as well clinical and safety outcomes isolated DMVO stroke to compare them with standard medical or without intravenous thrombolysis (IVT) in daily practice.This multicenter case-control study analyzed patients who were treated primary distal cerebral artery (PCA) P2 P3 segment. These received (with IVT) at 1 23...
Background Evidence supporting a potential benefit of thrombectomy for distal medium vessel occlusions (DMVOs) the anterior cerebral artery (ACA) is, to knowledge authors, unknown. Purpose To compare clinical and safety outcomes between mechanical (MT) best medical treatment (BMT) with or without intravenous thrombolysis primary isolated ACA DMVOs. Materials Methods Treatment Primary Medium Vessel Occlusion Stroke, TOPMOST, is an international, retrospective, multicenter, observational...
Recent progress with smaller retrievers has expanded the ability to reach distal brain arteries. We herein report recanalization, bleeding complications and short-term clinical outcomes smallest currently known low profile thrombectomy device in patients primary or secondary medium vessel occlusion (DMVO).We performed a retrospective analysis of 115 receiving mechanical (MT) DMVO using extended Thrombolysis Cerebral Infarction (eTICI), European Cooperative Acute Stroke Study (ECASS) II...
Background and Purpose: A tandem occlusion of the intracranial circulation extracranial carotid artery (ICA) occurs in 10-20% all strokes based on large vessel (LVO). The optimal treatment strategy for those patients is unknown. We report our management outcome these a single-center cohort. Materials Methods: retrospectively identified analyzed treated by Mechanical Thrombectomy (MT) an LVO associated with ICA between April 2009 May 2016 (163/1,645, 9.9%). following data was collected:...
Background: The optimal endovascular strategy for reperfusing distal medium-vessel occlusions (DMVO) remains unknown. This study evaluates angiographic and clinical outcomes of thrombectomy strategies in DMVO stroke the posterior circulation. Methods: TOPMOST (Treatment Primary Medium Vessel Occlusion Stroke) is an international, retrospective, multicenter, observational registry patients treated between January 2014 June 2020. analyzed endovascularly isolated primary cerebral artery P2 P3...
Background Balloon-assisted techniques can improve the endovascular treatment of cerebrospinal vascular malformations. The aim this study was to report first clinical multicenter experience with new Scepter Mini dual-lumen microballoon catheter. Methods Patients cerebral or spinal malformations treated at seven European neurovascular centers were retrospectively reviewed. Clinical data, angiographic features malformations, procedural parameters including type application, navigability,...
Background and Purpose: Subgroup analysis of the SAMMPRIS trial showed a higher rate periprocedural perforator strokes with Wingspan stent in basilar artery patients symptomatic intracranial atherosclerotic stenosis (ICAS). It remains unclear whether angioplasty (PTA) alone or combination other types (PTAS) will yield similar results perforator-bearing segments anterior posterior circulation. Methods: We retrospectively analyzed complication rate, long term outcome stroke etiology 59...
Background Whether to approach distal occlusions endovascularly or not in medium-sized vessels secondary proximal large vessel occlusion stroke remains unanswered. Objective To investigates the technical feasibility and safety of thrombectomy for posterior circulation distal, medium (DMVO). Methods TOPMOST (Treatment fOr Primary Medium Occlusion STroke) is an international, retrospective, multicenter, observational registry patients treated cerebral artery occlusions. This study subanalysis...
Background Numerous questions regarding procedural details of distal stroke thrombectomy remain unanswered. This study assesses the effect anesthetic strategies on procedural, clinical and safety outcomes following for medium vessel occlusions (DMVOs). Methods Patients with isolated DMVO from TOPMOST registry were analyzed regard to (ie, conscious sedation (CS), local (LA) or general anesthesia (GA)). Occlusions in P2/P3 A2–A4 segments posterior anterior cerebral arteries (PCA ACA),...
Endovascular embolization is a feasible treatment for cranial dural arteriovenous fistulas (DAVFs). New embolic agents aim to improve the success of DAVF embolization.To assess safety, efficacy, and short-term outcome DAVFs using new liquid agent Squid.The LIQUID study prospective, observational multicenter on high-grade (Cognard type ≥3) with Squid. The primary measures were safety (ie, morbidity mortality), as well occlusion rate 90 180 days after treatment.In eight centers, 53 patients...
<h3>BACKGROUND AND PURPOSE:</h3> Spinal arteriovenous fistulas are challenging to cure by endovascular means, with a risk of incomplete occlusion or delayed recurrence. The authors report herein their preliminary experience using the pressure cooker technique for embolization spinal fistulas. <h3>MATERIALS METHODS:</h3> Fifteen patients (8 men; mean age, 60.3 years) underwent an treatment fistula (12 dural and 3 epidural fistulas) in 2 different institutions technique. Two microcatheters...
Self-expanding stents are increasingly being deployed for stent-assisted coiling or flow diversion of intracranial aneurysms. Complications related to stent misbehavior may arise, however, including lack expansion, device displacement, parent vessel thrombosis. We present our experience various removal techniques (stentectomy) with a focus on technical and clinical outcomes.Stentectomy was attempted either single device, the Alligator, Microsnare, Solitaire, by combining Microsnare second...
Background and purpose To evaluate the durability safety of complete intracranial aneurysm occlusion at one year using low-profile braided LVIS EVO stent. Materials methods This is a retrospective, monocentric, observational study unruptured wide-necked aneurysms treated with stent-through-balloon technique after balloon-assisted hydrocoil embolization. Imaging clinical data were assessed by two blinded independent neuroradiologists neurologists, respectively. Primary endpoint was...
<h3>Introduction</h3> Thrombectomy is the standard treatment for acute ischemic stroke. No failed has been so far established. As a rescue method, double stent-retriever(SR) seems to be effective and associated with low complication rate. <h3>Aim of Study</h3> To prove efficacy saftey Double Stentreiver as method after Thrombectomy. <h3>Methods</h3> In retrospective analysis, all patients having received mechanical double-SR therapy following single-SR thrombectomy between 2010–2022 were...
<h3>Introduction</h3> Many studies demonstrated that endovascular embolization is an effective and safe technique for the occlusion of cranial dural arteriovenous fistulas (DAVFs). However, quality life (QoL) treated patients was not yet addressed before. <h3>Aim Study</h3> In this post-hoc analysis LIQUID study we aimed to systematically investigate QoL with high-grade DAVFs embolization. <h3>Methods</h3> The a prospective multi-center on DAVF embolic agent Squid. EQ5D-3L used assessment...
