Video-Based Propagation of Tacit Knowledge During Coil Embolization of Intracranial Aneurysms

Neuroendovascular treatment of cerebral aneurysms is considered a basic procedure for neurosurgeons and interventional neuroradiologists; however, its critical technical nuances, termed "tacit knowledge," are challenging to impart. This study aimed to evaluate the efficacy of our novel video recording and editing method in enhancing trainees' experience.

A wearable camera (wearable recording) and multiple media sources in a hybrid operating room (hybrid recording) were used to capture procedural details such as audio and conversation, thus enabling a re-experience. Trainees condensed both recordings into summary videos, and a supervisor subsequently evaluated them. Six trainees watched the following 3 videos: Video 1, only hybrid recording; Video 2, only wearable recording; and Video 3, both wearable and hybrid recordings synchronized, and then provided semiquantitative evaluations ranging from 0 (not useful at all) to 5 (extremely useful).

We examined 64 unruptured cerebral aneurysm coil embolizations using hybrid wearable recording methods. Video 3 received the highest rating among all participants (5 ± 0 [mean ± standard deviation]), while Videos 1 and 2 received relatively lower ratings (Video 1:3.8 ± 0.7; Video 2:4.2 ± 0.4). The educational impact of video editing across all videos was rated highly (4.4 ± 0.8). The respondents showed diverse opinions on editing time, with some perceiving it as less time-consuming than other surgery video edits (3.4 ± 1.1).

Our hybrid and wearable recording and editing methods facilitated the propagation of tacit knowledge of coil embolization and enhanced surgical education by enabling more efficient learning of technical tips.
