Smartphone-assisted minimally invasive neurosurgery

Mauricio Mandel, Carlo Emanuel Petito, Rafael Tutihashi, Wellingson Paiva, Suzana Abramovicz Mandel, Fernando Campos Gomes Pinto, Almir Ferreira de Andrade, Manoel Jacobsen Teixeira, and Eberval Gadelha Figueiredo

C omputer technology is increasingly being integrated into medical care. 16 , 18 , 19 Use of handheld computers has become more common among health care providers and throughout the general population. 10 , 28 , 31 , 34 In particular, over the last decade there have been rapid developments in smartphones. These mobile phones can perform many of the functions of the most sophisticated computer devices, particularly with regard to speed, storage capacity, optical resolution, and camera functionality; 17 and their compact size makes them useful in settings that

Image-guided endoscopic surgery for spontaneous supratentorial intracerebral hematoma

Guo-chen Sun, Xiao-lei Chen, Yuan-zheng Hou, Xin-guang Yu, Xiao-dong Ma, Gang Liu, Lei Liu, Jia-shu Zhang, Hao Tang, Ru-Yuan Zhu, Ding-Biao Zhou, and Bai-nan Xu

. We report here a simple, fast, and economical positioning and surgical procedure for endoscopic evacuation of intracerebral hematomas. The method is based on virtual reality using a hospital's picture archiving and communication system (PACS) and augmented reality using the a smartphone and the Sina neurosurgical assist Android smartphone app, which assists surgeons in precisely placing the obturator and introducing the sheath to the desired target. Methods Patient Population Twenty-five patients with a mean (± SD) age of 65.4 ± 11.1 years were included in the

App-assisted external ventricular drain insertion

Behzad Eftekhar

insertion is based on fixed anatomical landmarks and does not take individual variation into consideration. A patient-tailored approach based on the use of augmented-reality techniques can address this shortcoming. Smartphones are popular and have potential for intra-operative use in association with augmented-reality mobile device applications (apps). Although there are available apps that could be used for EVD placement, the need for certain features and the potential for further applications by other devices like augmented-reality glasses (e.g., Google Glass) led to

was compared with the freehand pass technique, the Ghajar Guide tended to permit accurate ventricle placement in fewer attempts, although there was no statistically significant difference between the two techniques. 15 Since then, endoscopy, ultrasonography, and neuronavigation are being increasingly used in selected cases. A recent nationwide survey revealed that more than half of neurosurgeons and neurosurgical residents in the US prefer to use image-guided techniques, 18 and recent trials are aiming to use smartphone technology in conjunction with MRI and CT

conical than the standard drill bit ( Figs. 3B and 7 ). Numerous attempts to improve the accuracy of EVD catheter targeting have been reported in the literature to date, including robotic, smartphone, neuronavigation, ultrasound, flat detector CT, and real-time fluoroscopy–assisted EVD placement, as well as using a mechanical guide device (the Ghajar guide). 3 , 14 – 18 While image guidance techniques have been demonstrated to improve EVD placement accuracy, 15 none of them have been widely introduced into clinical practice. Moreover, O’Neill et al. analyzed

passed through the open slot into the ventricle. After catheter placement, the clip secures the catheter to avoid inadvertent catheter manipulation during tunneling and closure. This design enables accurate catheter placement while minimizing interruptions to the existing procedural workflow ( Video 1 ). While other technologies have been developed, there remain practical factors limiting their widespread adoption. Neuronavigation, such as with the AxiEM Electromagnetic StealthStation (Medtronic), smartphone-navigated apps, and 3D tracking systems, has been found to
