Three-dimensional Anaglyph Indocyanine Green Video Angiography: A New Technology for Cerebrovascular Surgeries

Background and Aim: Indocyanine Green (ICG) angiography has become the standard of practice in many centers managing cerebrovascular diseases. Though 3D stereoscopic recording of the surgeries has received widespread attention, there is a need for a technology to display and record realtime 3D ICG angiographies. In this study, we designed and constructed an ICG angiography camera to display the realtime 3D ICG angiographies. Methods and Materials/Patients: Our project had three phases. In phase I, a handmade ICG camera was designed and constructed in our laboratory. The second phase included creating a 3D camera to display realtime images in 3D anaglyph format. In the last phase, we developed a 3D ICG camera to demonstrate 3D ICG angiographies in realtime. Results: We successfully completed all three phases of the project and could display realtime 3D ICG angiography of a mouse mesenteric arteries, recorded it, and took pictures. Conclusion: We proposed a method and proved its feasibility for producing a 3D ICG angiography camera to be mounted on the next generation of neurosurgical microscopes.
