The use of the YELLOW 560 nm surgical microscope filter for sodium fluorescein-guided resection of brain tumors: Our preliminary results in a series of 28 patients

摘要

Objective: Sodium fluorescein (Na-Fl) is a fluorescent dye that accumulates in tumoral tissues via disrupted blood-brain barrier. It has been used in fluorescence-guided surgery for various brain tumors. Herein, we report our initial experience and preliminary results for the first 28 patients who were operated on under Na-Fl guidance with the use of a special filter on the surgical microscope.
