Case report: Use of markerless augmented reality system for ventriculoperitoneal shunt placement.

ABSTRACT:

Background

Ventriculoperitoneal (VP) shunt placement is one of the most commonly performed neurosurgical procedures, yet failure rates remain very high. Surface landmarks are typically used to guide VP shunt placement, but they are not reliable in identifying the target anatomy. Augmented reality (AR) is a promising new technology that has the potential to improve the accuracy and effectiveness of neurosurgical procedures. We describe the use of AR for the surgical planning of a VP shunt.

Case description

A 62-year-old male with a history of subarachnoid hemorrhage presented with delayed hydrocephalus. A computed tomography scan was obtained that confirmed dilated ventricles, requiring a right VP shunt. The patient was brought to the operating room, where the AR system was used for visualization and planning.

Conclusion

In this study, we describe the use of AR for VP shunt placement. The AR system consists of a Microsoft HoloLens 2 head-mounted display and a novel markerless registration system, which was used to register patient-specific 3D models onto the patient's head for visualizing target anatomy and planning an operative approach. The AR system was used to plan the VP shunt placement in the operating room. This system is easy to use and provides a visualization of the patient's anatomy, which can be used to plan an optimal trajectory. We believe that this has the potential to improve the accuracy and outcomes of VP shunt placements, and further studies are needed to characterize the system's accuracy and benefits.

Project description:BackgroundPostoperative communicating hydrocephalus has been described in the literature commonly associated with treatment of ruptured intracranial aneurysms; however, it is also reported to occur following other intracranial interventions such as meningioma resection and decompressive hemicraniectomy. In 2011, Burkhardt et al. reported the incidence of postoperative hydrocephalus following skull base meningioma resection was twice as high as resection of meningiomas in other regions.[1] They found that age and increased length of surgery were associated with higher rates of postoperative hydrocephalus. Our patient, a 76-year-old man, initially presented with the left-hand paresthesias and numbness before the revelation of a large sphenoid planum meningioma on workup imaging. He underwent surgical resection due to developing cranial nerve deficits and personality changes in an extensive procedure that required approximately 8 h to complete. His postoperative course, given the factors above, included the development of hydrocephalus.Case descriptionHe was taken to the operating room for ventriculoperitoneal shunt placement, as displayed in this video case report, which highlights our surgical and sterile techniques, intraoperative ultrasound to ensure appropriate ventricular placement, and a single-port laparoscopic technique for direct visualization of placement of the abdominal catheter. After shunt placement, his course was complicated by a small tract hemorrhage, which resolved without further treatment. He was observed to have an improvement in mental function that occurred over the following 2-3 days before being discharged to an outpatient rehabilitation facility for continued care.ConclusionVentriculoperitoneal shunt placement is an effective and safe procedure for the treatment of postoperative communicating hydrocephalus when performed with appropriate techniques as displayed in the associated video case report. The patient gave informed consent for surgery and video recording. Institutional Review Board approval was deemed unnecessary.

Project description:BackgroundGait and balance impairments are common in neurological diseases, including stroke, and negatively affect patients' quality of life. Improving balance and gait are among the main goals of rehabilitation. Rehabilitation is mainly performed in clinics, which lack context specificity; therefore, training in the patient's home environment is preferable. In the last decade, developed rehabilitation technologies such as virtual reality and augmented reality (AR) have enabled gait and balance training outside clinics. Here, we propose a new method for gait rehabilitation in persons who have had a stroke in which mobile AR technology and a sensor-based motion capture system are combined to provide fine-grained feedback on gait performance in real time.ObjectiveThe aims of this study were (1) to investigate manipulation of the gait pattern of persons who have had a stroke based on virtual augmentation during overground walking compared to walking without AR performance feedback and (2) to investigate the usability of the AR system.MethodsWe developed the ARISE (Augmented Reality for gait Impairments after StrokE) system, in which we combined a development version of HoloLens 2 smart glasses (Microsoft Corporation) with a sensor-based motion capture system. One patient with chronic minor gait impairment poststroke completed clinical gait assessments and an AR parkour course with patient-centered performance gait feedback. The movement kinematics during gait as well as the usability and safety of the system were evaluated.ResultsThe patient changed his gait pattern during AR parkour compared to the pattern observed during the clinical gait assessments. He recognized the virtual objects and ranked the usability of the ARISE system as excellent. In addition, the patient stated that the system would complement his standard gait therapy. Except for the symptom of exhilaration, no adverse events occurred.ConclusionsThis project provided the first evidence of gait adaptation during overground walking based on real-time feedback through visual and auditory augmentation. The system has potential to provide gait and balance rehabilitation outside the clinic. This initial investigation of AR rehabilitation may aid the development and investigation of new gait and balance therapies.
