Dear Sir:With interest, we have read the article by Roberto Rey-Dios and Aaron A. Cohen-Gadol: Technical principles and neuro-surgical applications of fluorescein fluorescence using a microscope-integrated fluorescence module (Acta Neurochir. [2013] 155:701706).
The authors explore new technology proffered by the Zeiss company, the YELLOW 560 system for neurosurgery using fluorescein.
The images obtained for vascular surgery appear impressive. In contrast to the Zeiss INFRARED 800 or FLOW 800 systems, which use indocyanine green (ICG), fluorescein is directly visible within the vessels, which the surgeon can inspect and directly manipulate. FLOW 800, on the other hand, gives an image only available on the screen of the microscope, but has the advantage of giving semi-quantitative information that has been explored by our and other groups [2, 3].
Years ago, before we had access to the INFRARED 800 system, we used fluorescein for vascular surgery with the Zeiss Blue 400 system....
