Advances in robotic technology have been adopted various subspecialties of both open and minimally invasive surgery, offering benefits such as enhanced surgical precision accuracy with reduced fatigue the surgeon. Despite advantages, applications to endovascular neurosurgery remained largely unexplored because technical challenges miniaturization devices that can reach complex tortuous vasculature brain. Although some commercial systems enable manipulation conventional guidewires for...
Prior randomized trials have generally shown harm or no benefit of stenting added to medical therapy for patients with symptomatic severe intracranial atherosclerotic stenosis, but it remains uncertain as whether refined patient selection and more experienced surgeons might result in improved outcomes.To compare plus vs alone stenosis.Multicenter, open-label, randomized, outcome assessor-blinded trial conducted at 8 centers China. A total 380 transient ischemic attack nondisabling,...
Despite the well-established potent benefit of mechanical thrombectomy (MT) for large vessel occlusion (LVO) stroke, access to MT has not been studied globally. We conducted a worldwide survey countries on 6 continents define (MTA), disparities in MTA, and its determinants global scale.Our was 75 through Mission Thrombectomy 2020+ network between November 22, 2020, February 28, 2021. The primary end points were current annual operator availability, center availability. MTA defined as...
Mechanical thrombectomy (MT) has revolutionized the treatment of acute ischemic stroke (AIS) due to large vessel occlusion (LVO), but its efficacy and safety in medium (MeVO) remain less explored. This multicenter, retrospective study aims investigate incidence clinical outcomes perforations (confirmed by extravasation during an angiographic series) MT for AIS caused MeVO.
Acute ischemic stroke (AIS) caused by distal medium vessel occlusions (DMVOs) represents a significant proportion of overall cases. While intravenous thrombolysis (IVT) has been primary treatment, advancements in endovascular procedures have led to increased use mechanical thrombectomy (MT) DMVO patients. However, symptomatic intracerebral hemorrhage (sICH) remains critical complication AIS, particularly after undergoing intervention. This study aims identify factors associated with sICH patients MT.
Background Brain arteriovenous malformations (AVMs) are abnormal connections between feeding arteries and draining veins, associated with significant risks of haemorrhage, seizures other neurological deficits. Preoperative embolization is commonly used as an adjunct to microsurgical resection, the aim reducing intraoperative complications improving outcomes. However, efficacy safety this approach remain controversial. Methods This study a subanalysis Multicenter International Study for...
Background: Arteriovenous malformations (AVMs) are complex vascular anomalies with a high risk of hemorrhage and neurological deficits, especially when located in eloquent brain regions. The eloquence an AVM location is critical factor the treatment planning, influencing both complications long-term functional outcomes. This study aims to compare outcomes between non-eloquent AVMs. Methods: multicenter, retrospective utilized data from Multicenter International Study for Treatment Brain AVMs...
Introduction: The impact of multiple feeding arteries on clinical outcomes cerebral arteriovenous malformations (AVMs) is not well understood. This study aims to compare between AVMs with versus single arteries. Patients and Methods: Data from the Multicenter International Study for Treatment Brain (MISTA) consortium were analyzed. Propensity score matching (PSM) was used balance cohorts. Subgroup analysis conducted ruptured unruptured different treatment options, multivariable logistic...
OBJECTIVE Flow diversion for posterior circulation aneurysms performed using the Pipeline embolization device (PED) constitutes an increasingly common off-label use otherwise untreatable aneurysms. The safety and efficacy of this treatment modality has not been assessed in a multicenter study. METHODS A retrospective review prospectively maintained databases at 8 academic institutions was years 2009 to 2016 identify patients with treated PED placement. RESULTS total 129 consecutive underwent...
Background The efficacy of endovascular treatment (EVT) in acute ischaemic stroke due to distal medium vessel occlusion (DMVO) remains uncertain. Our study aimed evaluate the safety and EVT compared with best medical management (BMM) DMVO. Methods In this prospectively collected, retrospectively reviewed, multicentre cohort study, we analysed data from Multicentre Analysis primary Distal occlusions: effect Mechanical Thrombectomy registry. Patients DMVO M2, M3 M4 segments who underwent or...
Background Poor venous outflow (VO) profiles are associated with unfavorable outcomes in patients acute ischemic stroke caused by large vessel occlusion (AIS-LVO), despite achieving successful reperfusion. The objective of this study is to assess the association between mortality and prolonged transit (PVT), a novel visual qualitative VO marker on CT perfusion (CTP) time maximum (Tmax) maps. Methods We performed retrospective analysis prospectively collected data from consecutive adult...
Pretreatment CT Perfusion (CTP) parameter rCBV < 42% lesion volume has recently been shown to predict 90-day mRS. In this study, we aim assess the relationship between and a radiographic follow-up infarct delineated on FLAIR images. retrospective evaluation of our prospectively collected database, included acute stroke patients triaged by multimodal imaging, including angiography perfusion with confirmed anterior circulation large vessel occlusion 9 January 2017 10 2023.

Abstract Background and Purpose Distal medium vessel occlusions (DMVOs) are a significant contributor to acute ischemic stroke (AIS), with collateral status (CS) playing pivotal role in modulating damage progression. We aimed explore baseline characteristics associated CS AIS‐DMVO. Methods This retrospective analysis of prospectively collected database enrolled 130 AIS‐DMVO patients from two comprehensive centers. Baseline characteristics, including patient demographics, admission National...
Stroke remains a major health concern globally, with oral anticoagulants widely prescribed for stroke prevention. The efficacy and safety of mechanical thrombectomy (MT) in anticoagulated patients distal medium vessel occlusions (DMVO) are not well understood.
Acute ischemic stroke (AIS) from primary medium vessel occlusions (MeVO) is a prevalent condition associated with substantial morbidity and mortality. Despite the common use of mechanical thrombectomy (MT) in AIS, predictors poor outcomes MeVO remain poorly characterized.
Background The combination of intravenous thrombolysis (IVT) with mechanical thrombectomy (MT) may have clinical benefits for patients medium vessel occlusion. Purpose To examine whether MT combined IVT is associated different outcomes than alone in acute ischemic stroke (AIS) and Materials Methods This retrospective study included consecutive adult AIS occlusion treated or at 37 academic centers North America, Asia, Europe. Data were collected from September 2017 to July 2021. Propensity...
Recent large core trials have highlighted the effectiveness of mechanical thrombectomy (MT) in acute ischemic stroke with vessel occlusion. Variable perfusion-imaging thresholds and poor Alberta Stroke Program Early Computed Tomography Score reliability underline need for more standardized, quantitative ischemia measures MT patient selection. We aimed to identify computed tomography perfusion parameter most strongly associated outcomes patients stroke-large occlusion significant cores.
