hybrid operating suite

BACKGROUND: Anaesthesia care outside of the standard operating room (OR) can be challenging. This prospective matched case-pair study describes the difference in anaesthesia clinicians' perception of safety, workload, anxiety, and stress in two settings by comparing similar neurosurgical procedures performed in either the OR or a remote hybrid room with intraoperative MRI (MRI-OR). METHODS: A visual numeric scale for safety perception and validated instruments for workload, anxiety, and stress were administered to enrolled anaesthesia clinicians after induction of anaesthesia and at the end of eligible cases...

OBJECTIVE: In moyamoya disease (MMD), blood flow to the internal carotid artery (ICA) system is supplied via the basal fine vascular network, leptomeningeal anastomoses, and transdural collateral vessels from the external carotid artery (ECA). After revascularization, there is a dramatic change in cerebral perfusion to the ECA system. Understanding this shift in blood supply is important for evaluating treatment efficacy and elucidating the postoperative pathophysiology. However, anatomical and quantitative methods for doing so have not yet been established...

A 17-year-old female presented to the emergency room with an arrow sticking out the right aspect of her neck. Her vital signs were stable with systolic blood pressure of 117 mmHg, without either tachycardia, dyspnea, or signs of active bleeding. She was fully conscious with intact sensory and motor function on all extremities. Computed Tomography (CT) showed that the tip of the arrowhead lodged at the transverse foramen of the third cervical vertebra. Digital subtraction angiography revealed that the arrowhead lies posterior to the right vertebral artery, narrowly missing it by about two millimeters...

Lung cancer is the most lethal cancer type in Taiwan and worldwide. Early detection and treatment advancements have improved survival. However, small peripheral pulmonary nodules (PPN) biopsy is often challenging, relying solely on bronchoscopy with radial endobronchial ultrasound (EBUS). Augmented fluoroscopy overlays the intra-procedural cone-beam computed tomography (CBCT) images with fluoroscopy enabling real-time three-dimensional localization during bronchoscopic transbronchial biopsy. The hybrid operating room (HOR), equipped with various types of C-arm CBCT, is a perfect suite for PPN diagnosis and other interventional pulmonology...

Single-cavity dual-combs comprise a rapidly emerging technology platform suitable for a wide range of applications like optical ranging, equivalent time sampling, and spectroscopy. However, it remains a challenging task to develop a dual-comb system that exhibits low relative frequency fluctuations to allow for comb line resolved measurements, while simultaneously offering high average power and short pulse durations. Here we combine a passively cooled and compact dual-comb solid-state oscillator with a pair of core-pumped Yb-fiber-based amplifiers in a master-oscillator power-amplifier (MOPA) architecture...

BACKGROUND: Pediatric intracranial dural arteriovenous fistulas (dAVFs) are rare, complex entities usually presenting with macrocephaly from increased intracranial pressures at a young age. In the setting of a symptomatic intracranial dAVF that has undergone multiple endovascular treatments with subsequent recurrence or failed embolization attempts, the intracranial venous system can become inaccessible by traditional transvenous and transarterial routes. Direct puncture of the venous sinus for endovascular access after surgical exposure is a viable option...

OBJECTIVES: We developed a novel wireless localization technique after electromagnetic navigation bronchoscopy-guided radiofrequency identification marker placement for fluoroscopically invisible small lung lesions. We conducted an observational study to investigate the feasibility of this technique and retrospectively compared 2 marking approaches with or without cone-beam computed tomography. METHODS: Consecutive patients from January 2021 to March 2022 in our institution were enrolled...

INTRODUCTION: Abdominopelvic injuries are common, and bleeding occurring in both cavities requires various bleeding control techniques i.e., laparotomy, angiographic embolization (AE), and orthopedic fixation. Hence, the use of Trauma Hybrid Operating Room (THOR) in abdominopelvic injuries has theoretical advantages including rapid bleeding control and minimizing patient transportation. The objective of the present study is to evaluate the impact of THOR in abdominopelvic injuries. METHOD: A pre-post intervention study of abdominopelvic injury patients requiring both surgery and interventional radiology (IR) procedures for bleeding control from January 2015 to May 2020 was conducted...

WEST (tungsten environment in steady-state tokamak) is starting operation for the first time with a water-cooled full tungsten divertor, enabling long pulse operation. Heating is provided by radiofrequency systems, including lower hybrid current drive (LHCD). In this context, a compact multi-energy hard x-ray camera has been installed for energy and space-resolved measurements of the electron temperature, the fast electron tail density produced by LHCD and runaway electrons, and the beam-target emission of tungsten at the target due to fast electron losses interacting with the divertor plates...

The aim of the research was to check the possibility of using the non-destructive method of acoustic emission to assess the condition of concrete without dispersed reinforcement and with various additions of curved steel fibres, during three-point bending. An important aspect of the research proposed in the article is the use of a hybrid method of analysis, which involves complementing the results of strength tests, the results of numerical calculations and the results of strain distributions recorded with a digital image correlation system (DIC System, in this research GOM Suite optical system)...

BACKGROUND: Open surgical and percutaneous endovascular procedures aimed at arresting traumatic life-threatening hemorrhage are usually performed in rapid serial fashion by surgeons and interventional radiologists; truly simultaneous procedures require modifications in technique, workflow and team collaboration. The primary objective of this study was to prospectively audit outcomes in patients with ongoing hemorrhage who underwent truly simultaneous open and percutaneous procedures. METHODS: We prospectively evaluated the cases of all severely injured patients who required an open and percutaneous procedure within the hybrid RAPTOR (resuscitation with angiography, percutaneous techniques and operative repair) suite at the Foothills Medical Centre, Calgary, Alberta, Canada, between Apr...

PURPOSE: The aim of this study was to describe the utilization of the RAPTOR suite (hybrid theatre) for trauma patients. Ideally, this is used to achieve haemorrhage control in time-critical patients that may require damage control surgery (DCS) and/or interventional radiological (IR) procedures concurrently. METHODS: A single-centre, retrospective study identifying all trauma patients that were treated at the level I trauma centre during 2011-2016 was performed...

Identification of bone erosions and quantification of erosion volume is important for rheumatoid arthritis diagnosis, and can add important information to evaluate disease progression and treatment effects. High-resolution peripheral quantitative computed tomography (HR-pQCT) is well suited for this purpose, however analysis methods are not widely available. The purpose of this study was to develop an open-source software tool for the identification and quantification of bone erosions using images acquired by HR-pQCT...

The hybrid operating room (HOR) utilizes advanced imaging technology to improve intra-operative visualization and facilitate efficient care in procedures that are relatively image dependent. The robotic C-arm provides improved 2D image quality and is capable of large volume three-dimensional fluoroscopy (3DF) that can rapidly create multiplanar CT like images. Here we discuss on the technique, utility, potential benefits, pitfalls, and complications of using the hybrid suite with and without intra-arterial balloon occlusion for pelvic and acetabular fracture surgery...

The 'domestication syndrome' defines a suite of features that domesticated animals possess as the result of the artificial selection operated by Homo sapiens since the Neolithic. An interesting anthropological question is whether such features, including increased tameness and reduced aggression, apply to all domesticated forms. We investigated this issue in the domestic pig ( Sus scrofa ). We video-recorded and analysed aggression and social play (mostly play-fighting) sessions from piglets (three litters; n = 24) and wild boar hybrids (domestic pig mother x wild boar father; three litters; n = 27) from 6-50 days of age, raised in the same woodland/grassland habitat and extensive farming management (ethical farm 'Parva Domus', Cavagnolo, Torino)...

BACKGROUND: 99m Tc-Sestamibi Single Photon Emission Computed Tomography/Computed Tomography (SPECT/CT) contributes to the non-invasive differentiation of renal oncocytoma (RO) from renal cell carcinoma (RCC) by characterising renal tumours as Sestamibi positive or Sestamibi negative regarding their 99m Tc-Sestamibi uptake compared to the non-tumoral renal parenchyma. PURPOSE: To determine whether 99m Tc- Sestamibi uptake in renal tumour and the non-tumoral renal parenchyma measured using Standard Uptake Value (SUV) SPECT, has a beneficial role in differentiating RO from RCC...

BACKGROUND: Coil migration during endovascular treatment for an intracranial aneurysm is rare. When it occurs intraoperatively, it often mandates prompt endovascular retrieval or, as a salvage maneuver, microsurgical extraction if it fails endovascularly. OBSERVATIONS: The authors presented a case of immediate coil migration during embolization of a giant intracranial cavernous segment of the internal carotid aneurysm. The patient immediately underwent emergency surgical extraction after unsuccessful endovascular retrieval attempts...

OBJECTIVE: Shinshu University Hospital has advanced operating rooms including a mobile computed tomography (mCT) room, Smart Cyber Operating Theater (SCOT) with intraoperative magnetic resonance imaging, hybrid operating room (hOR) with intraoperative image-guided surgery, and conventional operating rooms. We investigated the characteristics of cases assigned to each operating room. METHODS: Five hundred forty neurosurgery cases from January 2018 to April 2021 were analyzed...

Understanding the structure and evolution of natural cognition is a topic of broad scientific interest, as is the development of an engineering toolkit to construct artificial cognitive systems. One open question is determining which components and techniques to use in such a toolkit. To investigate this question, we employ agent-based AI, using simple computational substrates (i.e., digital brains) undergoing rapid evolution. Such systems are an ideal choice as they are fast to process, easy to manipulate, and transparent for analysis...
