Augmented reality enhanced tele-proctoring platform to intraoperatively support a neuro-endovascular surgery fellow

Background Remote tele-proctoring has been conducted in neuro-endovascular surgery, however, evidence to support its use in the fellowship training is limited. We demonstrate a novel augmented reality tele-proctoring platform to enable a remote attending to guide a fellow. Methods A consecutive series of neuro-endovascular cases were performed by a neuro-endovascular fellow with remote guidance from an attending surgeon. The fellow and attending were connected using a commercially available cloud-based platform designed to capture and stream up to four live video feeds from a clinical environment to a remote user. In this setting, two video streams were obtained directly from the anteroposterior and lateral cameras on the biplane. Additional video of the operator from a telescopic camera was streamed live to the remote attending surgeon. The attending could provide immediate vocal feedback and also deploy the platform's augmented reality tools to communicate with the fellow in the angiography suite. Results A total of 10 cases were performed on eight patients utilizing the cloud-based tele-proctoring platform to facilitate instruction. The series included diagnostic angiograms and interventions such as intracranial balloon angioplasty, carotid stenting, and intracranial stenting. All cases were a technical success. No complications or deaths occurred. When compared to similar cohort of 10 cases prior to these which utilized a traditional instruction paradigm; we saw no differences in contrast use (p = 0.38), fluoroscopy time (p = 0.85), or technical success. Conclusions This study demonstrates successful use of an augmented reality tele-proctoring platform to guide a neuro-endovascular fellow through complex neuro-interventional procedures from a remote setting.
