Neuroendoscopy began with a desire to visualize the ventricles and deeper structures of the brain. Unfortunately, the technology available to early neuroendoscopists was not sufficient in most cases for these purposes. The unique perspective that neuroendoscopy offered was not fully realized until key technological advances made reliable and accurate visualization of the brain and ventricles possible. After this technology was incorporated into the device, neuro-endoscopic procedures were rediscovered by neurosurgeons. Endoscopic third ventriculostomy and other related procedures are now commonly used to treat a wide array of neurosurgically managed conditions. A seemingly limitless number of neurosurgical applications await the endoscope. In the future, endoscopy is expected to become routine in modern neurosurgical practice and training.

Improvement in fiber optics and imaging paved the way for tremendous advancements in neuroendoscopy. These advancements have led to increasingly widespread use of the endoscope in neurosurgical procedures, which in turn incited a technological revolution leading to new approaches, instruments, techniques, and a diverse armamentarium for the treatment of a variety of neurosurgical disorders. Soft-tissue removal is often a rate-limiting aspect to endoscopic procedures, especially when the soft tissue is dense or fibrous. The authors review a series of cases involving patients treated between August 2009 and October 2010 with a new device (the NICO Myriad), a non–heat-generating, oscillating, cutting, and tissue removal instrument that can be used through the working channel of the endoscope as well as in open neurosurgical procedures. They used this device in 14 purely endoscopic intracranial procedures and 1 endoscope-assisted keyhole craniotomy. They report that the device was easy to use and found that tissue resection was more efficient than with other available endoscopic instruments, especially in the resection of fibrotic tissue. There were no observed device-related complications. The authors discuss the technical aspects of using this device in endoscopic resection of pituitary tumors, craniopharyngiomas, and colloid cysts. They also demonstrate its use in hydrocephalus and intraventricular clot removal and discuss its potential use in other neurosurgical disorders.

The freehand technique for insertion of an external ventricular drain (EVD) is based on fixed anatomical landmarks and does not take individual variations into consideration. A patient-tailored approach based on augmented-reality techniques using devices such as smartphones can address this shortcoming. The Sina neurosurgical assist (Sina) is an Android mobile device application (app) that was designed and developed to be used as a simple intraoperative neurosurgical planning aid. It overlaps the patient's images from previously performed CT or MRI studies on the image seen through the device camera. The device is held by an assistant who aligns the images and provides information about the relative position of the target and EVD to the surgeon who is performing EVD insertion. This app can be used to provide guidance and continuous monitoring during EVD placement. The author describes the technique of Sina-assisted EVD insertion into the frontal horn of the lateral ventricle and reports on its clinical application in 5 cases as well as the results of ex vivo studies of ease of use and precision. The technique has potential for further development and use with other augmented-reality devices.

For any new technology to gain acceptance, it must not only adequately fill a true need, but must also function optimally within the confines of coexisting technology and concurrently available support systems. As an example, over the first decades of the 20th century, a number of drill designs used to perform cranial bone cuts appeared, fell out of favor, and later reappeared as certain supportive technologies emerged. Ultimately, it was the power source that caused one device to prevail. In contrast, a brilliant imaging device, designed to demonstrate an axial view of the lumbar spine, was never allowed to gain acceptance because it was immediately superseded by another device of no greater innovation, but one that performed optimally with popular support technology. The authors discuss the factors that have bearing on the evolution of neurosurgical technology.

A haptic device is an actuated human–machine interface utilized by an operator to dynamically interact with a remote environment. This interaction could be virtual (virtual reality) or physical such as using a robotic arm. To date, different mechanisms have been considered to actuate the haptic device to reflect force feedback from the remote environment. In a low-force environment or limited working envelope, the control of some actuation mechanisms such as hydraulic and pneumatic may be problematic. In the development of a haptic device, challenges include limited space, high accuracy or resolution, limitations in kinematic and dynamic solutions, points of singularity, dexterity as well as control system development/design. Furthermore, the haptic interface designed to operate in a magnetic resonance imaging environment adds additional challenges related to electromagnetic interference, static/variable magnetic fields, and the use of magnetic resonance–compatible materials. Such a device would allow functional magnetic resonance imaging to obtain information on the subject’s brain activity while performing a task. When used for surgical trainees, functional magnetic resonance imaging could provide an assessment of surgical skills. In this application, the trainee, located supine within the magnet bore while observing the task environment on a graphical user interface, uses a low-force magnetic resonance–compatible haptic device to perform virtual surgical tasks in a limited space. In the quest to develop such a device, this review reports the multiple challenges faced and their potential solutions. The review also investigates efforts toward prototyping such devices and classifies the main components of a magnetic resonance–compatible device including actuation and sensory systems and materials used.

Dans l'objectif de traiter les tumeurs cérébrales difficilement accessibles avec les outils chirugicaux actuels, Robeauté développe un microrobot innovant dans l'objectif de naviguer dans les zones cérébrales profondes avec un minimum d'invasivité. L'objectif de cette thèse a été de développer et de valider un système de suivi ultrasonore transcrânien du microrobot afin de pouvoir implémenter des commandes robotiques et garantir ainsi la sûreté et l'efficacité de l'intervention.L'approche proposée consiste à placer trois émetteurs ultrasonores sur la tête du patient, et à embarquer un récepteur ultrasonore sur le microrobot. En connaissant la vitesse du son dans les tissus biologiques et l'épaisseur de crâne traversée, il est possible d'estimer les distances entre les émetteurs et le récepteur par mesure de temps de vol, et d'en déduire sa position 3D par trilatération. Une preuve de concept a d'abord été réalisée à travers un modèle de crâne d'épaisseur constante, démontrant une précision de localisation submillimétrique. Pour se placer dans un contexte clinique, le système a ensuite été évalué à travers un modèle de calvaria dont l'épaisseur et la vitesse du son en face de chaque émetteur ont été déduites par tomodensitométrie. Le système a démontré une précision de localisation moyenne de 1.5 mm, soit une dégradation de la précision d'1 mm comparée à celle du suivi à travers le modèle de crâne d'épaisseur constante, expliquée par l'incertitude apportée par l'épaisseur hétérogène de la calvaria. Enfin, trois tests pré-cliniques, sans possibilité d'évaluer l'erreur de localisation, ont été réalisés : (i) un test post-mortem sur un humain, (ii) un test post-mortem sur une brebis, (iii) et un test in vivo sur une brebis.De futures pistes d'amélioration du système de suivi ont été proposées, telles que (i) l'utilisation de simulation de propagation ultrasonore transcrânienne basée sur une tomodensitométrie pour la prise en compte des hétérogénéités du crâne, (ii) la miniaturisation du capteur ultrasonore embarqué sur le microrobot, (iii) ainsi que l'intégration d'une imagerie ultrasonore pour la visualisation de la vascularisation locale autour du microrobot, permettant ainsi de réduire le risque de lésions et de détecter d'éventuelles angiogenèses pathologiques
With the aim of treating brain tumors difficult to access with current surgical tools, Robeauté is developing an innovative microrobot to navigate deep brain areas with minimal invasiveness. The aim of this thesis was to develop and validate a transcranial ultrasound-based tracking system for the microrobot, in order to be able to implement robotic commands and thus guarantee both the safety and the effectiveness of the intervention.The proposed approach consists in positioning three ultrasound emitters on the patient's head, and embedding an ultrasound receiver on the microrobot. Knowing the speed of sound in biological tissue and the skull thickness crossed, it is possible to estimate the distances from the emitters to the receiver by time-of-flight measurements, and to deduce its 3D position by trilateration. A proof of concept was first carried out using a skull phantom of constant thickness, demonstrating submillimeter localization accuracy. The system was then evaluated using a calvaria phantom whose thickness and speed of sound in front of each emitter were deduced by CT scan. The system demonstrated an mean localization accuracy of 1.5 mm, i.e. a degradation in accuracy of 1 mm compared with the tracking through the skull phantom of constant thickness, explained by the uncertainty brought by the heterogeneous shape of the calvaria. Finally, three preclinical tests, without the possibility of assessing localization error, were carried out: (i) a post-mortem test on a human, (ii) a post-mortem test on a ewe, (iii) and an in vivo test on a ewe.Further improvements to the tracking system have been proposed, such as (i) the use of CT scan-based transcranial ultrasound propagation simulation to take account of skull heterogeneities, (ii) the miniaturization of the ultrasound sensor embedded in the microrobot, (iii) as well as the integration of ultrasound imaging to visualize local vascularization around the microrobot, thereby reducing the risk of lesions and detecting possible pathological angiogenesis

Although femoral artery catheterization has been the mainstay of arterial access for cerebral angiography, there has been a recent increase in the use of transradial access among neurointerventionalists. Despite its widespread use among interventional cardiologists, there is a paucity of evidence for its use in the neurosurgical literature. With the constant evolution of device technology and the need of multimodal treatments for complex neurovascular pathologies, most neurointerventionalists resort to femoral artery access because of the vessel’s larger diameter and having been trained with that approach. However, transradial access confers a number of benefits, most notably lower risk of vascular complications, shorter recovery, and increased patient satisfaction and cost reduction. Femoral artery catheterization requires patients to tolerate a painful and uncomfortable procedure, with associated potential complications such as pseudo-aneurysm formation, retroperitoneal hematoma, and artery occlusion. Compared with groin access, radial artery catheterization has been shown to confer a lower risk of local neurovascular complications and improved quality-of-life metrics. This book is the first of its kind, detailing step by step all the technical nuances of the transradial approach in the neurointerventional world, from diagnostic cerebral angiograms to neurointerventional procedures. This is the perfect book for physicians who decided to make the transition of their practice to transradial.

Neurosurgical infections include those of devices such as external ventricular drains and permanent shunts (e.g. ventriculo-peritoneal and ventriculo-atrial). Organisms can form biofilm on the surface of such devices, sometimes sufficient to cause blockage. Patients may present with signs of meningitis or of shunt blockage. In the intensive care setting patients may have fever and/or deterioration in their neurological status. These infections are complex to manage as they usually require removal/revision of the device and delivery of high levels of antibiotics to the central nervous system. Each of these has risks and needs to be expertly managed. This case describes an acute infection in an external ventricular drain.

Stroke remains a major public health issue and the second leading cause of death worldwide. The Hippocratic Corpus used the word apoplexy to describe a person collapsing while retaining pulse and respiration. This is believed to be the first written description of stroke. The theories of what caused stroke evolved over the years. When autopsies were performed stroke was attributed to emboli and thrombi formation. Carotid endarterectomies (CEA) were then performed for the treatment of stroke. Originally CEA were seen with skepticism but the North American Symptomatic Carotid Endarterectomy trial (NASCET) and the European Carotid Surgery trial (ECS) helped restore their efficacy in the management of ischemic stroke. A milestone in the management of ischemic stroke was the use of intravenous tissue plasminogen activator (tPA). Secondary to the limitations of the use of tPA other avenues were sought which included intraarterial recombinant prourokinase and mechanical thrombectomy. The field of mechanical thrombectomy continues to be rapidly changing and evolving. Various randomized controlled trials and meta-analysis have been conducted in order to evaluate who will benefit from mechanical thrombectomies, the timing, the best device to use and the role of combining this intervention with the administration of intravenous tPA.

Abstract Neurosurgical operations are long and intensive medical procedures, during which the surgeon must constantly have an unobscured view of the brain in order to be able to properly operate, and thus must use a variety of tools to clear obstructions (like blood and fluid) from the operating area. Currently, cotton balls are the most versatile and effective option to accomplish this as they absorb fluids, are soft enough to safely manipulate the brain, act as a barrier between other tools and the brain, and function as a spacer to keep anatomies of the brain open and visible during the operation. While cotton balls allow neurosurgeons to effectively improve visibility of the operating area, they may also be accidentally left in the brain upon completion of the surgery. This can lead to a wide range of post-operative risks including dangerous immune responses, additional medical care or surgical operations, and even death. This project seeks to develop a unique medical device that utilizes ultrasound technology in order to minimize cotton retention after neurosurgical procedures in order to reduce undesired post-operative risks, and maximize visibility.

Nowadays, the number of technical systems in the operating room increases constantly. This ongoing spread of technology has significant impacts on the individual working process steps of the surgical team. Besides improving the therapeutic quality, these changes may also lead to new human-induced risks for patients, therapists and third parties. In particular, within intra-operative activities, which depend on a safe and fast operation, surgeons and nurses rely on sophisticated and efficient solutions in terms of Human-Machine-Interfaces in order to perform their tasks reliably and assuredly. Therefore, proprietary integrated workstations with a central usage cockpit have been provided for the operating theatre in recent years. At the Chair of Medical Engineering, a surgical integrated workstation with open interfaces for the integration of various medical devices from different manufacturers is currently been developed in the context of the BMBF (Federal Ministry of Education and Research) funded project OR.NET. For this purpose a suitable central user interface (e.g. multi-function foot switch, touch screen, diagnostic monitor, etc.) will be implemented, in a way that the functions of the various (networked) devices can be offered to the user by a central user interface. The design of the Human-Machine-Interface therefore depends on the available input and output devices, the interaction elements of the graphical user interface, the available medical technical equipment, as well as the medical intervention and the particular process steps and the environmental conditions within the operating room. In this work, a concept for the development of a Medical Device User Interface Profile (UIP) will be presented, using the characterization of process-dependent medical device functions for the modular design of a central user interface in the integrated operating room of the future. The use of standardized UI Profiles should allow the manufacturers to integrate their medical devices, respectively the provided functions in the OR.NET network, without disclosing the risk analysis and related confidential know-how or proprietary information. The UI Profiles will allow both, an automated optimized selection and composition of various user interfaces, and implicitly an optimal design of a central GUI with respect to the criteria of usability and an integrated human risk analysis in terms of Human-Machine Interaction. Specific operation process steps within a neurosurgical workflow will be the framework for the validation process of the UI Profiles. Till now, the UIP concept has been tested within the integration of an ultrasound dissector and an OR microscope.

Brain tumors are among the most feared complications of cancer and they occur in 20–40% of adult cancer patients. Despite numerous advances in treatment, the prognosis for these patients is poor, with a median survival of 4–8 months. The primary reasons for poor survival rate are the lack of good continuous imaging modality for intraoperative intracranial procedures and the inability to remove the complete tumor tissue due to its placement in the brain and the corresponding space constraints to reach it. Intraoperative magnetic resonance imaging (MRI) supplements the surgeon’s visual and tactile senses in a way that no other imaging device can achieve resulting in less trauma to surrounding healthy brain tissue during surgery. To minimize the trauma to surrounding healthy brain tissue, it would be beneficial to operate through a narrow surgical corridor dissected by the neurosurgeon. Facilitating tumor removal by accessing regions outside the direct “line-of-sight” of the neurosurgical corridor will require a highly dexterous, small cross section, and MRI-compatible robot. Developing such a robot is extremely challenging task. In this paper we report a preliminary design of 6-DOF robot for possible application in neurosurgery. The robot actuators and body parts are constructed from MRI compatible materials. The current prototype is 0.36” in diameter and weighs only 0.0289 N (2.95 grams). The device was actuated using Flexinol® which is a shape memory alloy manufactured by Dynalloy, Inc. The end-effector forces ranged from 12 mN to 50 mN depending on the robot configuration. The end-effector force to robot weight ratio varied from 0.41 to 1.73. During trials the robot motion was repeatable and the range of motion of the robot was about 90 degrees for the end-effector when one side shape memory alloy (SMA) channel was actuated. The actuation time from the start to finish was about 2.5 s.

Introduction: Ischemic stroke is responsible for about 62% of all stroke cases. The lifetime risk of having a stroke is approximately 25%. Worldwide, stroke is one of the leading causes of mortality and disability. The causes are diverse, and the etiology must always be investigated in order to initiate specific treatment and adequate prophylaxis. Objectives: To report a case of ischemic stroke in a young woman after bronchoscopy with endotracheal tube replacement on an elective basis. Methods: Information was obtained through clinical follow-up in a neurology ward. Results: Patient, female, 27 years old, married, brown, with a history of polytrauma in 2015, after a bicycle accident, with the need for hospitalization in the intensive care unit, remaining intubated for nine days. Neurosurgical intervention was not necessary. The patient was discharged without any device, remaining functional, but two months later, she evolved with dyspnea, being diagnosed with tracheal stenosis, thus, a tracheostomy was necessary. In an outpatient routine, she was hospitalized for endotracheal tube replacement in October 2022. In the immediate postoperative period, she presented desaturation, requiring orotracheal intubation, sedation and breathing on mechanical ventilation. As she woke up weakly after ceasing sedation, a neurological investigation was initiated, being diagnosed with multiple areas of ischemic infarcts and identifying patent foramen ovale (PFO), moderate-grade paradoxical transseptal shunt as the most likely cause of the ischemic stroke.

Virtual reality based surgical training have a great potential as an alternative to traditional training methods. In neurosurgery, state-of-the-art training devices are limited and the surgical experience accumulates only after so many surgical procedures. Incorrect surgical movements can be destructive; leaving patients paralyzed, comatose or dead. Traditional techniques for training in surgery use animals, phantoms, cadavers and real patients. Most of the training is based either on these or on observation behind windows. The aim of this research is the development of a novel virtual reality training system for neurosurgical interventions based on a real surgical microscope for a better visual and tactile realism. The simulation works by an accurate tissue modeling, a force feedback device and a representation of the virtual scene on the screen or directly on the oculars of the operating microscope. An intra-operative presentation of the preoperative three-dimensional data will be prepared in our laboratory and by using this existing platform virtual organs will be reconstructed from real patients’ images. VISPLAT is a platform for virtual surgery simulation. It is designed as a patient-specific system that provides a database where patient information and CT images are stored. It acts as a framework for modeling 3D objects from CT images, visualization of the surgical operations, haptic interaction and mechanistic material-removal models for surgical operations. It tries to solve the challenging problems in surgical simulation, such as real-time interaction with complex 3D datasets, photorealistic visualization, and haptic (force-feedback) modeling. Surgical training on this system for educational and preoperative planning purposes will increase the surgical success and provide a better quality of life for the patients. Surgical residents trained to perform surgery using virtual reality simulators will be more proficient and have fewer errors in the first operations than those who received no virtual reality simulated education. VISPLAT will help to accelerate the learning curve. In future VISPLAT will offer more sophisticated task training programs for minimally invasive surgery; this system will record errors and supply a way of measuring operative efficiency and performance, working both as an educational tool and a surgical planning platform quality.

Laser interstitial thermal therapy (LITT) is a neurosurgical procedure that involves using heat treatment to ablate glioblastomas in the brain. Current methods for placing probes in LITT involve straight trajectory pathways. This limitation often requires surgeons to make multiple trajectories or leave undesired margins. There has been extensive work in steerable needles, concentric tube cannulas, and flexible surgical tools. In this work, we present an approach which focuses on providing steerability to tools that aren’t inherently steerable. To do this, we developed a curved port delivery system that leverages an active cannula for the deployment of a plastic, flexible port that delivers existing surgical tools. We present an initial prototype coupled with feasibility results illustrating that the port can be placed to steer probes to a desired location.
