Augmented reality–assisted roadmaps during periventricular brain surgery

Abstract

Visualizing major periventricular anatomical landmarks intraoperatively during brain tumor removal is a decisive measure toward preserving such structures and thus the patient's postoperative quality of life. The aim of this study was to describe potential standardized preoperative planning using standard landmarks and procedures and to demonstrate the feasibility of using augmented reality (AR) to assist in performing surgery according to these “roadmaps.” The authors have depicted stepwise AR surgical roadmaps applied to periventricular brain surgery with the aim of preserving major cognitive function. In addition to the technological aspects, this study highlights the importance of using emerging technologies as potential tools to integrate information and to identify and visualize landmarks to be used during tumor removal.

The intraoperative use of augmented and mixed reality technology to improve surgical outcomes: A systematic review

“…Of comparative studies, there were 9 retrospective cohort studies, 15 prospective cohort studies and 7 randomised controlled trials (RCTs). Most studies were performed in neurosurgery, 33 general surgery 22 and orthopaedic surgery 14 . Figure 6 shows studies of different designs grouped by authors' surgical specialities.…”

“…Postoperative complications were reported in 13 (6.6%) patients with various tumour types and locations, 27,28 while in six studies patients were reported to be without postoperative complications. [29][30][31][32][33][34] No other data on surgical outcomes were reported in these eight studies, aside from two patients spending two and 6 days in inpatient care following meningioma resection. 27,29 Seven studies of 217 patients-two retrospective cohort studies and five case series-investigated AR in cerebrovascular surgery (see Table A3).…”

Corona mortis and pelvic dissection: Understanding the relationship between anatomical structures and bone areas

“…This emerging technology is a tool that will enable us to integrate information and identify and visualize the landmarks previously described for use in pelvic and acetabular surgery. Our anatomical landmarks description and their relationships to different bone areas involved in traumatology can be used to define a “roadmap” in the preoperative planning of an augmented reality (AR) surgery (Bernard et al., 2021; Bernard & Bijlenga, 2022).…”

Mixed Reality for Cranial Neurosurgical Planning: A Single-Center Applicability Study With the First 107 Subsequent Holograms

“…[17][18][19][20][21] Their results supported the conclusion that VR only moderately affected conventional patient positioning but it did help better detection of pathology-specific anatomic relationships. The use of AR has also been extended to intraoperative visualization of major anatomic landmarks, as documented by Bernard et al, 22 to improve periventricular structure preservation in 13 cases of tumor removal.…”
