E 104 Image guidance for mechanical thrombectomy in stroke using an optical see through head mounted display (OST HMD): proof of concept and rationale

Background and Purpose Optical see-through head-mounted displays (OST-HMD) can enable a mixed reality (MR) experience for neurointerventionalists during procedures encompassing high resolution radiographic imaging and an unhindered view of the procedural site. The authors present a technical note detailing an approach to mechanical thrombectomy in stroke utilizing an OST-HMD as an alternative to traditional angiography suite display monitors.Methods Mixed reality visualization was achieved using the Microsoft HoloLens system. An anatomically realistic flow model was employed to perform the procedure. A commercially available guide sheath, intermediate aspiration catheter, microcatheter and mechanical thrombectomy device were utilized to perform a mechanical thrombectomy of a right M1 thrombus. The head mounted display created a real-time mixed reality environment by superimposing …
