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.
Background and Purpose— Radial artery catheterization is an alternate route of access that has started to gain more widespread use for neuroendovascular procedures, there have been few studies describe its safety efficacy. We present our institution’s experience in performing interventions via a transradial approach, with excellent clinical outcomes patient satisfaction measures. Methods— conducted retrospective analysis identified 223 patients who underwent 233 consecutive radial at...
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.
Introduction: First pass effect (FPE), achievement of complete recanalization (mTICI 2c/3) with a single pass, is significant predictor favorable outcomes for endovascular treatment (EVT) in large vessel occlusion stroke (LVO). However, data concerning the impact on functional and predictors FPE medium occlusions (MeVO) are scarce. Patients Methods: We conducted an international retrospective study MeVO cases. Multivariable logistic modeling was used to establish independent FPE. Clinical...
Middle meningeal artery (MMA) embolization has recently emerged as a treatment option for chronic subdural hematoma (cSDH). It is considered simple and potentially safe endovascular procedure.To compare between 2 different embolic agents; onyx (ethylene vinyl alcohol) emboparticles (polyvinyl alcohol particles-PVA) of cSDH.A retrospective analysis all patients who underwent MMA cSDH in comprehensive centers August 2018 December 2021. Primary outcomes were failure need rescue surgical...
Background For acute proximal intracranial artery occlusions, contact aspiration may be more effective than stent‐retriever for first‐line reperfusion therapy. Due to the lack of data regarding medium vessel occlusion thrombectomy, we evaluated outcomes according technique in a large, multicenter registry. Methods Imaging, procedural, and clinical patients with occlusions (M2, A1, or P1) distal (M3, A2, P2, further) treated at 37 sites 10 countries were analyzed endovascular (stent‐retriever...
OBJECTIVE By providing a more physiological approach to the treatment of intracranial aneurysms, Pipeline embolization device (PED) has revolutionized endovascular aneurysms. Although there are many flow diverters on market, authors report their experience with PED, first diverter be approved by Food and Drug Administration. They aimed assess efficacy safety PED diversion for wide range as well look at factors affecting occlusion. METHODS This is retrospective study prospectively maintained...
Background Moyamoya is a chronic occlusive cerebrovascular disease of unknown etiology causing neovascularization the lenticulostriate collaterals at base brain. Although revascularization surgery most effective treatment for moyamoya, there still no consensus on best surgical modality as different studies provide outcomes. Objective In this large case series, we compare outcomes direct (DR) and indirect revascularisation (IR) our results to literature in order reflect moyamoya. Methods We...
Background: Efficient management of acute ischemic stroke is critical to reducing disability and mortality. The hub-and-spoke telestroke model has been developed extend specialized care regions with limited resources, ensuring timely diagnosis treatment. Objective: To evaluate the effectiveness a large-scale network in delivering care, focusing on rates thrombolysis mechanical thrombectomy, treatment timelines, patient outcomes. Methods: We conducted retrospective analysis 9,702 patients...
Introduction: Moyamoya disease (MMD) is a chronic cerebrovascular disorder characterized by progressive stenosis or occlusion of the internal carotid arteries and development collateral moyamoya vessels. Surgical revascularization commonly used to prevent future ischemic events in ischemic-type MMD, but there remains high rate stroke perioperatively. This study aims analyze predictive factors for perioperative patients with MMD undergoing surgical using large multicenter database. Methods:...
Introduction: Aneurysmal subarachnoid hemorrhage (aSAH) is a life-threatening condition after which patients are at risk for vasospasm and delayed cerebral ischemia (DCI). Nimodipine, calcium channel blocker, used to reduce the of DCI. Despite its widespread application, specific effects on hemodynamics cortical activity poorly characterized. It remains unknown whether this potent therapy may have unintended harmful consequences in some patients, could potentially be mitigated or avoided....

INTRODUCTION: In an era of increasingly diverse neurosurgical workforce, one the key challenges recognized is need to ensure fair and equitable pay. METHODS: We performed a retrospective study American Association Medical Colleges (AAMS) Faculty Salary Survey, years 2017 2023. Financial compensation data for full-time academic faculty were stratified by rank, gender, race/ethnicity. The total was calculated sum fixed/contractual salary, medical malpractice supplement, bonus/incentive...
INTRODUCTION: While recent evidence has demonstrated the safety and efficacy of endovascular thrombectomy (EVT) for acute basilar artery occlusions, few studies have explored benefit EVT posterior cerebral (PCA) occlusions. METHODS: The Nationwide Readmission Database years 2020 2021 was queried. Adult patients (>17 old) undergoing PCA occlusions were identified using ICD-10-CM coding system. Unique patient linkage numbers used to follow identify readmission rates. Patients grouped by no...
INTRODUCTION: In 2018, the JC and AHA introduced a new stroke care certification for Thrombectomy-Capable Stroke Centers, increasing both access number of proceduralists performing endovascular thrombectomies(EVT) nationwide. However, dispersing overall volume centers located in close proximity may have unclear effects on patient outcome. METHODS: We performed retrospective cohort study using 2020 Florida State Inpatient Database. included adult patients who had diagnosis AIS underwent EVT...
INTRODUCTION: Transcarotid artery revascularization (TCAR) has been established as an effective surgical option for symptomatic carotid disease, relying on flow reversal a proximal neuroprotection strategy. Despite its effectiveness, may not be tolerated in certain patients. These include those with anatomic variations the intracranial circulation, such isolated cerebral hemisphere, and multiple cranio-cervical occlusions. In other cases, efficient cannot certainty, e.g., when treating...
The current trends in academic neurosurgery physician compensation are not well studied. aim of this study was to investigate recent U.S. faculty by gender, race/ethnicity, and geographic region. We performed a secondary analysis the Association American Medical Colleges (AAMC) Faculty Salary Survey, years 2017 2023. Financial data for full-time were stratified rank, race/ethnicity. 2023 AAMC Survey included responses 1,383 members departments medical schools. During period, median increased...
INTRODUCTION: Several series have reported on the complication rates of diagnostic cerebral angiography (DCA). Changes in procedural indications, catheter technologies, and access methods necessitate an investigation into demographics complications DCA a modern practice. METHODS: A retrospective review was conducted patients who underwent between 2013 2020. Demographics, clinical information, were collected. Multivariate analysis utilized to identify potential factors associated with...
