Prospective observational study.The aim of this study was to evaluate the accuracy pedicle screw placement using augmented reality surgical navigation (ARSN) in a clinical trial.Recent cadaveric studies have shown improved for thoracic spine ARSN with intraoperative 3D imaging, without need periprocedural x-ray. In study, we used same system place screws and lumbosacral 20 patients.The performed hybrid operating room an integrated encompassing table, motorized flat detector C-arm 2D/3D...
A cadaveric laboratory study.The aim of this study was to assess the feasibility and accuracy thoracic pedicle screw placement using augmented reality surgical navigation (ARSN).Recent advances in spinal have shown improved lumbosacral but limited benefits spine. 3D intraoperative imaging instrument may allow placement, without use x-ray fluoroscopy, thus opens route image-guided minimally invasive therapy spine.ARSN encompasses a table, motorized flat detector C-arm with 2D/3D capabilities,...
Cadaveric laboratory study.To assess the feasibility and accuracy of minimally invasive thoracolumbar pedicle screw placement using augmented reality (AR) surgical navigation.Minimally spine (MIS) surgery has increasingly become method choice for a wide variety pathologies. Navigation technology based on AR been shown to be feasible, accurate, safe in open procedures. may also used MIS surgery.The navigation was installed hybrid operating room (OR). The OR includes table, motorized flat...
Abstract This study aimed to compare screw placement accuracy and clinical aspects between Augmented Reality Surgical Navigation (ARSN) free-hand (FH) technique. Twenty patients underwent spine surgery with using ARSN were matched retrospectively a cohort of 20 FH technique cases for comparison. All performed by the same surgeon. Matching was based on diagnosis similar proportions screws placed in thoracic lumbosacral vertebrae both groups. Accuracy assessed postoperative scans according...
Study Design. Cadaveric animal laboratory study. Objective. To evaluate the feasibility and accuracy of pedicle cannulation using an augmented reality surgical navigation (ARSN) system with automatic instrument tracking, yielding feedback position in relation to deep anatomy. Summary Background Data. Minimally invasive spine surgery (MISS) has possibility reducing exposure resulting shorter hospital stays, lower blood loss infection rates compared open but drawback limiting visual surgeon...
Abstract BACKGROUND Treatment of several spine disorders requires placement pedicle screws. Detailed 3-dimensional (3D) anatomic information facilitates this process and improves accuracy. OBJECTIVE To present a workflow for novel augmented-reality-based surgical navigation (ARSN) system installed in hybrid operating room anatomy visualization instrument guidance during screw placement. METHODS The includes exposure, imaging, automatic creation 3D model, path planning surgery as well the...
Objective To evaluate the efficacy of early intracranial pressure (ICP)-targeted treatment, compared to standard intensive care, in adults with community acquired acute bacterial meningitis (ABM) and severely impaired consciousness. Design A prospectively designed intervention-control comparison study adult cases from September 2004 January 2012. Patients Included patients were confirmed ABM-cases, aged 16–75 years, mental status on admission. Fifty-two patients, given ICP-targeted treatment...
Intracranial hemorrhage (ICH) is a recognized complication of adults treated with extracorporeal membrane oxygenation (ECMO) and associated increased morbidity mortality. However, the predictors ICH in this patient category are poorly understood. The purpose study was to identify ECMO-treated adult patients. We conducted retrospective review patients (≥18 years) ECMO at Karolinska University Hospital (Stockholm, Sweden) between September 2005 June 2016, excluding upon admission or those who...
Prospective observational study.To assess staff and patient radiation exposure during augmented reality surgical navigation in spine surgery.Surgical combination with intraoperative three-dimensional imaging has been shown to significantly increase the clinical accuracy of pedicle screw placement. Although this technique may total compared fluoroscopy, occupational can be minimized, as is free positioned behind protective shielding imaging. The treatment verification positions also...
The goal of this study was to develop and validate a system for automatic segmentation the spine, pedicle identification, screw path suggestion use with an intraoperative 3D surgical navigation system.
The primary treatment for malignant brain tumors is surgical resection. While gross total resection improves the prognosis, a supratotal may result in neurological deficits. On other hand, accurate intraoperative identification of tumor boundaries be very difficult, resulting subtotal resections. Histological examination biopsies can used repeatedly to help achieve but this not practically feasible due turn-around time tissue analysis. Therefore, techniques recognize types are investigated...
OBJECTIVE The aim of this study was to evaluate the accuracy (deviation from target or intended path) and efficacy (insertion time) an augmented reality surgical navigation (ARSN) system for insertion biopsy needles external ventricular drains (EVDs), two common neurosurgical procedures that require high precision. METHODS hybrid operating room–based ARSN system, comprising a robotic C-arm with intraoperative cone-beam CT (CBCT) integrated video tracking patient instruments using...
To investigate the accuracy of augmented reality (AR) navigation using Magic Leap head mounted device (HMD), pedicle screws were minimally invasively placed in four spine phantoms.AR provided by a combination conventional system integrated with (AR-HMD) was used. Forty-eight planned and inserted into Th11-L4 phantoms AR-HMD navigated instruments. Postprocedural CT scans used to grade technical (deviation from plan) clinical (Gertzbein grade) screws. The time for each screw placement...
BACKGROUND AND OBJECTIVES: Epilepsy is considered one of the most prevalent and severe chronic neurological disorders worldwide. Our study aims to analyze national trends in different treatment modalities for individuals with drug-resistant epilepsy investigate outcomes associated these procedural United States. METHODS: Using National Inpatient Sample database from 2010 2020, patients focal who underwent laser interstitial thermal therapy (LITT), open surgical resection, vagus nerve...
Spinal schwannomas are the second most common form of primary intradural spinal tumor. Despite being benign, they may cause cord compression and subsequently acute or chronic neurological dysfunction. The treatment is surgical resection. aim this study was to identify pre- postoperative predictors favorable outcomes after for schwannoma. All adult patients surgically treated schwannoma between 2006 2020 were eligible inclusion. Medical records imaging data retrospectively reviewed. outcome...
Abstract Purpose We aimed to investigate surgical outcomes in octogenarians with subaxial cervical spine injuries and determine the predictors of complications mortality. Methods Eligible for inclusion were all patients surgically treated between 2006 2018, either anterior or posterior fixation injuries. A cohort was identified matched 1:1 a corresponding younger adults. Primary perioperative Results Fifty-four included each octogenarian groups (median age: 84.0 vs. 38.5). While risks...
Background Intracranial hemorrhage (ICH) is a common complication in adults treated with extracorporeal membrane oxygenation (ECMO). The aim of this study was to identify predictors outcome and investigate intervention strategies following ICH development ECMO-treated adult patients.
