Book Review

Ivan Cabrilo, Karl Schaller
2016 European Neurology  
Book Review a fluid fashion -and delivers clearly defined 'Principles' and 'Guidelines' that the authors suggest for keyhole surgery to be performed successfully. Moreover, the text is vividly illustrated by an impressive collection of figures and images from the authors' practice. However, although this book's goal is to advocate keyhole surgery, it can arguably also be perceived as doing the opposite, namely, when the inexperienced reader is, quite understandably, warned to steer away from

The application of recent augmented reality techniques, for example, addresses this issue and may help to acquire this experience and to further minimise procedural invasiveness [1, 3] . This aspect is lacking in the authors' promotion of keyhole surgery, and that would merit a short discussion on the steps/advances the authors believe should be taken in the future to make keyhole surgery more accessible. Altogether, Principles and Practice of Keyhole Brain Surgery (videos included) is not only an instructive and pleasant read, but a book that we think the reader will regularly go back to. And yet the authors explicitly state that this work was not meant to be a reference book! But, although it intentionally does not review other groups' works in the field, it is a commendable effort in providing a comprehensive overview of the authors' longstanding experience in keyhole approaches, a reference in itself.

Jugular Foramen Meningioma with Transverse and Sigmoid Sinuses Invasion and Jugular Vein Extension

Ivan Radovanovic, Ivan Cabrilo, Carlo Schaller, Jeremy Brodard
2017 Central European Neurosurgery  
AbstractWe present the case of a jugular foramen meningioma with predominantly intraluminal invasion of the transverse, sigmoid sinuses, jugular bulb, and internal jugular vein with venous occlusion in a 45-year-old woman. Magnetic resonance imaging (MRI) of the brain and conventional angiography were performed preoperatively and revealed a right-sided extra-axial dural-based mass in the jugular foramen. The surgical approach was a high cervical approach with exposure of the internal carotid

The transverse, sigmoid sinuses, jugular bulb, and superior internal jugular vein were removed en bloc, and the exophytic intradural tumor extension around cranial nerves IX, X, XI, and XII was resected subtotally. Postoperatively, the patient presented a transient right facial weakness (House-Brackmann II). MRI showed partial resection. This is the first case report of a jugular foramen meningioma with transverse and sigmoid sinuses invasion and jugular vein extension in the adult population.

Cortical Surface Co-Registration based on MRI Images and Photos [article]

Benjamin Berkels, Ivan Cabrilo, Sven Haller, Martin Rumpf, Carlo Schaller
2013 arXiv   pre-print
Brain shift, i.e. the change in configuration of the brain after opening the dura mater, is a key problem in neuronavigation. We present an approach to co-register intra-operative microscope images with pre-operative MRI to adapt and optimize intra-operative neuronavigation. The tools are a robust classification of sulci on MRI extracted cortical surfaces, guided user marking of most prominent sulci on a microscope image, and the actual variational registration method with a fidelity energy for
more » ... 3D deformations of the cortical surface combined with a higher order, linear elastica type prior energy. Furthermore, the actual registration is validated on an artificial testbed with known ground truth deformation and on real data of a neuro clinical patient.

Cauda equina tumor surgery: how I do it

Enrico Tessitore, Ivan Cabrilo, Colette Boex, Karl Schaller
2012 Acta Neurochirurgica  
Tumors of the cauda equina usually require surgery due to their impingement on neighboring nerve roots, often resulting in pain and neurological deficits. Method The Authors first give a brief introduction on cauda equina tumors, followed by a description of the surgical anatomy, and then develop the microsurgical technique. In particular, tricks to avoid complications are presented, underlining the importance of intraoperative neuromonitoring. Conclusion Both microsurgical technique and
more » ... nitoring are important in cauda equina tumor surgery, the goal of which is to achieve complete resection while at the same time preserving neurological function.

Right insular damage decreases heartbeat awareness and alters cardio-visual effects on bodily self-consciousness

2015 Neuropsychologia  
Recent evidence suggests that multisensory integration of bodily signals involving exteroceptive and interoceptive information modulates bodily aspects of self-consciousness such as self-identification and self-location. In the so-called Full Body Illusion subjects watch a virtual body being stroked while they perceive tactile stimulation on their own body inducing illusory self-identification with the virtual body and a change in self-location towards the virtual body. In a related illusion,

Although brain imaging and neuropsychological evidence suggest that the insular cortex is a core region for interoceptive processing (such as cardiac perception and awareness) as well as for self-consciousness, it is currently not known whether the insula mediates cardio-visual modulation of self-consciousness. Here we tested the involvement of insular cortex in heartbeat awareness and cardio-visual manipulation of bodily self-consciousness in a patient before and after resection of a selective right neoplastic insular lesion. Cardio-visual stimulation induced an abnormally enhanced state of bodily self-consciousness; in addition, cardio-visual manipulation was associated with an experienced loss of the spatial unity of the self (illusory bi-location and duplication of his body), not observed in healthy subjects. Heartbeat awareness was found to decrease after insular resection. Based on these data we propose that the insula mediates interoceptive awareness as well as cardio-visual effects on bodily self-consciousness and that insular processing of interoceptive signals is an important mechanism for the experienced unity of the self.

Intraoperative monitoring of visual evoked potentials in patients undergoing transsphenoidal surgery for pituitary adenoma: a systematic review

Farizeh Jashek-Ahmed, Ivan Cabrilo, Jarnail Bal, Brett Sanders, Joan Grieve, Neil L. Dorward, Hani J. Marcus
2021 BMC Neurology  
Background Transsphenoidal surgery is the gold standard for pituitary adenoma resection. Although rare, a serious complication of surgery is worsened vision post-operatively. Objective To determine whether, in patients undergoing transsphenoidal surgery for pituitary adenoma, intraoperative monitoring of visual evoked potentials (VEP) is a safe, reproducible, and effective technological adjunct in predicting postoperative visual function. Methods The PubMed and OVID platforms were searched
more » ... en January 1993 and December 2020 to identify publications that (1) featured patients undergoing transsphenoidal surgery for pituitary adenoma, (2) used intraoperative optic nerve monitoring with VEP and (3) reported on safety or effectiveness. Reference lists were cross-checked and expert opinion sought to identify further publications. Results Eleven studies were included comprising ten case series and one prospective cohort study. All employed techniques to improve reliability. No safety issues were reported. The only comparative study included described a statistically significant improvement in post-operative visual field testing when VEP monitoring was used. The remaining case-series varied in conclusion. In nine studies, surgical manipulation was halted in the event of a VEP amplitude decrease suggesting a widespread consensus that this is a warning sign of injury to the anterior optic apparatus. Conclusions Despite limited and low-quality published evidence regarding intra-operative VEP monitoring, our review suggests that it is a safe, reproducible, and increasingly effective technique of predicting postoperative visual deficits. Further studies specific to transsphenoidal surgery are required to determine its utility in protecting visual function in the resection of complex pituitary tumours.
