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...
Background and Purpose- We aimed to evaluate the impact of brain atrophy on long-term clinical outcome in patients with acute ischemic stroke treated endovascular therapy, more specifically, test whether there are interactions between degree infarct volume, age, determining risk futile reperfusion. Methods- studied consecutive proximal anterior circulation intracranial arterial occlusions therapy achieving successful recanalization. Brain was evaluated baseline computed tomography global...
While there are reports of acute ischemic stroke (AIS) in coronavirus disease 2019 (COVID-19) patients, the overall incidence AIS and clinical characteristics large vessel occlusion (LVO) remain unclear.To attempt to establish COVID-19 patients an international cohort.A cross-sectional retrospective, multicenter study consecutive admitted with was undertaken from March 1 May 1, 2020 at 12 centers 4 countries. Out those centers, 9 all types strokes data were used calculate rate AIS. Three...
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 The aim of this study was to assess the technical success and procedural safety new Silk Vista device (SV) by evaluating intraprocedural periprocedural complication rate after its use in several institutions worldwide. Methods involved a retrospective review multicenter data regarding consecutive series patients with intracranial aneurysms, treated SV between September 2020 January 2021. Clinical, intra/periprocedural angiographic data, including approach, materials used, aneurysm...
Background Fetal posterior cerebral artery (FPCA) occlusion is a rare but potentially disabling cause of stroke. While endovascular treatment established for acute large vessel stroke, FPCA occlusions were excluded from ischemic stroke trials. We aim to report the feasibility, safety, and outcome mechanical thrombectomy in occlusions. Methods performed multicenter retrospective review consecutive patients who underwent occlusion. Primary was defined as an that identified on pre‐procedure...
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),...
Radial artery access for transarterial procedures has gained recent traction in neurointerventional due to decreased patient morbidity, technical feasibility, and improved satisfaction. Upper extremity transvenous (UETV) recently emerged as an alternative strategy the neurointerventionalist, but data are limited. Our objective was quantify use of UETV neurointerventions measure failure complication rates.An international multicenter retrospective review medical records patients undergoing or...
Abstract Background and Purpose The influence of intracranial arteriosclerosis (ICAR) on acute ischaemic stroke (AIS) prognosis is unclear. This study explored its impact, focusing ICAR subtypes categorized by carotid artery calcification (ICAC) patterns: intimal or atherosclerotic versus internal elastic lamina non‐atherosclerotic. aim was to determine their effect AIS in patients undergoing endovascular treatment (EVT). Methods prospective cohort included consecutive with anterior...
The COVID-19 pandemic is rapidly transforming the healthcare system, with telemedicine, or virtual health, being one of key drivers change. Smart glasses have recently been introduced to public and generated interest professionals as demonstrated by their early adoption in clinics hospitals. Observing procedures essential for young interventionalist-in-training, but sometimes it difficult them be able get volume exposure that they need. Here, we report first experience using smart...
While Balloon Guide Catheters (BGC) have been shown to increase the rate of reperfusion during mechanical thrombectomy (MT), its implementation with transfemoral approach is at times limited due unfavorable vascular anatomy.to determine safety, feasibility and performance transradial use 8 F BGC Flowgate2 procedures in patients anatomies (type 3 or bovine arch)Material/Methods: We performed a retrospective cohort study consecutive thrombectomies between January December 2019. Patient...
Flow diverter devices have become a routine first-line option for treatment of an increasing population intracranial aneurysms at many neurovascular centers. Despite the promising results flow stents on anterior circulation, incomplete occlusion presence fetal posterior circulation has been described several reports. Here we describe novel technical alternative to conventional diversion approach this specific subgroup using low-profile diverter, Silk Vista Baby. The device was selectively...
Importance: Coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome 2 (SARS-CoV-2), is a global pandemic that has been an immense burden on the healthcare systems all over world. While there are case reports of acute ischemic stroke (AIS) overall incidence in COVID -19 patients yet to be determined. Also, whether hypercoagulability seen COVID-19 leads larger thromboemboli and hence increase large vessel occlusion (LVOs) unclear. Design, Setting, Participants: This...
A simultaneous arterial and venous approach has been widely described for the endovascular treatment of dural arteriovenous fistula (DAVFs) recently malformation (AVMs). Conventional approaches are performed by direct internal jugular puncture or femoral access. Although complication rates low, there potential life-threatening complications that should be avoided. The advantages radial artery access have proven, nevertheless use upper limb veins in neurointervention rarely reported. We...
The neutrophil-lymphocyte ratio (NLR) is emerging as an important biomarker of acute physiologic stress in a myriad medical conditions, and confirmed poor prognostic indicator COVID-19.We sought to describe the role NLR predicting outcome COVID-19 patients undergoing mechanical thrombectomy for ischemic stroke.We analyzed with large vessel occlusion (LVO) strokes enrolled into international 12-center retrospective study laboratory-confirmed COVID-19, consecutively admitted between March 1,...
