Vessel perforation during thrombectomy is a severe complication and hypothesized to be more frequent medium vessel occlusion (MeVO) thrombectomy. The aim of this study was compare the incidence outcome patients with MeVO large (LVO) report on procedural steps that led perforation.
To demonstrate, by a cost-effectiveness analysis, the efficiency of mechanical thrombectomy (MT) versus medical management (MM) in patients with low Alberta Stroke Program Early CT Score (ASPECTS) from RESCUE Study.A model was designed to project both direct costs and quality-adjusted life-years (QALYs) MT MM eight European countries (Spain, UK, France, Italy, Belgium, Germany, Sweden, Netherlands). Our created based on previously published health-economic data those countries. Procedure...
Background: Acute intracranial stenting for the treatment of patients with large vessel occlusion in case failed reperfusion or severe stenosis is a growing practice. Our aim was to explore clinical and radiological outcome multicenter international registry. Methods: The RESISTANT registry retrospective stroke that underwent due an acute from 2016 2023. Primary endpoints at 90 days. Secondary efficacy were final (mTICI 2b-3), stent patency 24 hours. Safety outcomes included procedural...
Background: Intracranial stenting is increasingly performed after thrombectomy failure. Stent selection and procedural strategies are heterogenous between centers. Our aim to evaluate the clinical radiological impact of stent design among these patients. Methods: The RESISTANT registry a multicenter, international, retrospective study patients with acute ischemic stroke who underwent intracranial from 2016 2023. This analysis compares outcomes based on type evaluates role pre- post-stenting...
ABSTRACT Background and Purpose The superiority of achieving modified Treatment in Cerebral Ischemia (mTICI) from multiple passes versus mTICI 2b a single pass remains uncertain. We aimed to assess whether additional M1 occlusion patients with first‐pass score improved clinical functional outcomes. Methods analyzed Registry Combined vs. Single Thrombectomy Techniques registry data consecutive M1‐occlusion patients, comparing outcomes those 2b‐stopped after the first continued mechanical...
ABSTRACT Background and Purpose Large‐bore aspiration catheters (LBACs) are used for thrombectomy in large vessel occlusion (LVO), either as a standalone direct first‐pass technique or combined with stent retriever (ASR). LBAC design may influence ASR efficacy. We compared the safety performance of novel MIVI Q segmental catheter well‐established SOFIA device thrombectomy. Methods analyzed data from Registry cOmbined vS SinglE Thrombectomy TechnIques registry consecutive patients anterior...
Goyal et al described occlusions in M2/3, A2/3 and P2/3 as medium vessel (MeVOs); the only available controlled data of mechanical thrombectomy (MT) MeVOs is limited to middle cerebral artery M2 segment, suggesting that MT may be effective safe with high functional independence recanalization rates. The Stent retriever Assisted Vacuum-locked Extraction (SAVE) technique consists simultaneous use a stent distal aspiration catheter (DAC), removal both unit when performing pass; however, so far...
Background Efficient recanalization of occluded cerebral arteries is crucial in the treatment acute ischemic stroke. Double stent retrievers have shown potential to enhance rates on first pass. This study aims evaluate efficacy and safety double retriever technique predictors achieving first-pass effect patients with Methods prospective multicenter involved 209 from 16 comprehensive stroke centers Spain. Patients occlusions anterior circulation were treated using Aperio Hybrid retriever. The...
The optimal endovascular treatment (EVT) technique for middle cerebral artery (MCA) M2 segment occlusions remains unknown. We aim to analyze whether reperfusion rate, procedure times, procedure-related complications, and clinical outcome differed between patients with isolated who underwent stent-retriever (SR) alone versus combined SR contact aspiration (CA) as a front-line EVT.Patients EVT MCA-M2 occlusion were recruited from the prospectively ongoing ROSSETTI registry. Patients divided...
Introduction: Although stentrievers (SRs) have been a mainstay of mechanical thrombectomy (MT), and current guidelines recommend the use SRs in treatment large vessel occlusion stroke (LVO), there is paucity studies literature comparing directly against each other terms functional properties. Timely access to endovascular therapy ability restore intracranial flow safe, efficient, efficacious manner critical success MT. This study aimed investigate impact contemporary SR characteristics,...
Introduction: Thrombectomy complications remain poorly explored. This study aims to characterize periprocedural intracranial vessel perforation including the effect of thrombolysis on patient outcomes. Patients and methods: In this multicenter retrospective cohort study, consecutive patients with during thrombectomy between January 2015 April 2023 were included. Vessel was defined as active extravasation digital subtraction angiography. The primary outcome modified Rankin Scale (mRS) at 90...
Objective This study aims to describe our experience and safety considerations associated with the use of transulnar approach in neurointerventional procedures when radial access is not feasible. Methods A prospective exploratory analysis was conducted on 35 patients who underwent diagnostic or therapeutic neuroangiography via due limitations. Technical aspects approach, patient demographics, procedural details, complications were documented. Statistical performed using SPSS Statistics...
