This study's purpose was to improve understanding of the forces driving complex mechanical interaction between embolic material and current stroke thrombectomy devices by analyzing histological composition strength emboli retrieved from patients evaluating necessary for retrieval such in a middle cerebral artery (MCA) bifurcation model.
The development of new endovascular technologies and techniques for mechanical thrombectomy in stroke has greatly relied on benchtop simulators. This paper presents an affordable, versatile, realistic simulation model stroke.
Despite advancement of thrombectomy technologies for large-vessel occlusion (LVO) stroke and increased user experience, complete recanalization rates linger around 50%, one-third patients who have undergone successful still experience poor neurological outcomes. To enhance the understanding biomechanics failure modes, authors conducted an experimental analysis interaction emboli/artery/devices in first human brain test platform LVO described to date.In 12 fresh brains, 105 LVOs were...
Endovascular removal of emboli causing large vessel occlusion (LVO)-related stroke utilizing suction catheter and/or stent retriever technologies or thrombectomy is a new standard care. Despite high recanalization rates, 40% patients still experience poor neurological outcomes as many cases cannot be fully reopened after the first attempt. The development endovascular and techniques for mechanical requires more sophisticated testing platforms that overcome limitations phantom-based...
Objectives To integrate morphological, haemodynamic and mechanical analysis of carotid atheroma driving plaque disruption. Materials methods First, we analysed the phenotypes endarterectomy specimens in a photographic dataset A, matched them with likelihood preoperative stroke. Second, laser angioscopy was used to further define intact (dataset B) benchmark histology. Third, representative vascular geometries for each structural phenotype were Computational Fluid Dynamics (CFD), strength...
The complex management of intubation-related laryngeal injury makes prevention vital. purpose this study is to assess endotracheal tube (ETT) practices and preferences among intensivists at our institution.Chart review intubated patients intensivist survey were simultaneously performed in January 2016 August 2022. A height-to-ETT size ratio (H:ETT) was calculated for each patient the 2022 cohort. Intubated followed until tracheostomy, extubation, or death occurred. Surveys assessed ETT...
Abstract Background Oncocytic carcinoma (OCA) was recently reclassified as a distinct differentiated thyroid (DTC). Given its rarity, OCA studies are limited. This study describes the characteristics of in 20‐year cohort. Methods Retrospective analysis patients with at single tertiary care hospital from 2000 to 2021. Results Fifty‐one (22M:29F) were identified. The mean age diagnosis 60.3 years; 90% presented palpable mass; 24% had family history cancer. None vocal fold paresis. On...
Objective: Compare ventilation pressures of 2 endotracheal tube designs used in laser airway surgery clinical practice and with a benchtop model to elucidate differences understand the design elements that impact airflow dynamics. Methods: Ventilatory aerodynamic characteristics resistant stainless-steel (LRSS-ET) aluminum-wrapped silicone (LRAS-ET) were compared. parameters collected for 32 patients undergoing laser-assisted through retrospective chart review. An vitro simulation measured...
Pulse-synchronous tinnitus (PST) has been linked to multiple anatomical variants of the central venous outflow tract (CVOT) including sigmoid sinus (SS) dehiscence and diverticulum. This study investigates flow turbulence, pressure, wall shear stress along CVOT proposes a mechanism that results in SS PST.
Workability of a material is complex technological concept that related to both and process characteristics. Austempering heat treatment applied ferrous metals, mostly steel ductile iron. The present work was carried out study the workability properties AISI 1018 in austempering annealing condition then comparing with each other. testing using collar type specimen by compressing it till crack. diagrams have been plotted as function axial hoop strains at failure. result shows that, increases...
The bony facial trauma score (BFTS) is a rubric used to assess the severity of trauma.
Abstract Background The introduction of universal masking policies at many American healthcare institutions during the COVID-19 pandemic represented a major shift in infection prevention protocol. However, despite their widespread use, previous data on face masks as tool for preventing respiratory infections before COVID have been mixed, frequently showing no benefit. This study examines impact mask policy rates hospital-acquired pneumonia (HAP), ventilator-associated (VAP),...
Our understanding and management of carotid artery disease has largely relied on angiography, US MR. However, existing modalities cannot accurately identify the spectrum thrombogenic lesions vascular surface or reliably detect structural markers instability. Thus, natural history different histopathological hallmarks advanced complicated plaques is unknown, many patients with culprit substenotic are misdiagnosed cryptogenic stroke. An intraluminal approach to directly inspect endovascular...
<h3>Introduction</h3> Cerebrovascular test beds for large vessel occlusion (LVO) stroke are widely used to evaluate and develop new thrombectomy technologies strategies. Most of the studies on described fabrication cerebrovascular phantoms but not flow circuit clot analogs, which essential components replicate LVO in patients with stroke. In addition, made from different materials techniques may result biased testing results. However, such comparison has been studied. We describe detail...
<h3>Introduction</h3> Cerebral artery phantoms are valuable tools to test recanalization strategies of large vessel occlusion (LVO). However, these artificial models do not mimic the complex angioarchitecture and hemodynamic conditions human cerebrovasculature, embolus/endothelium interaction, nor response delicate arterial walls mechanical forces. In-vivo animal also available; however, such represent geometry, structure, or cerebral arteries. To overcome inadequacies, we present a bed...
<h3>Introduction</h3> Mechanical thrombectomy using a suction catheter, stent or the combination of both has recently become standard care for large vessel occlusion (LVO) stroke. However, complete recanalization (mTICI=3) with best neurological outcome can be achieved in only 50% cases. In addition, multiple devices and passes are usually needed to recanalize, prolonging procedure times, increasing risks damage. To improve our understanding interaction between embolus devices, this study we...
Introduction: Suction catheters and stent retrievers are based on the classical paradigm of “en bloc” removal emboli by generation tensile forces vacuum or device withdrawal. However, in this process elongate fracture leading to fragmentation. Fragments can migrate downstream remain impacted arterial wall resulting a residual occlusion. Hypothesis: Clot ingestion is biomechanically superior leads higher recanalization rates with less complications. Methods: To test hypothesis, we present...
