Introduction: In the last two decades the 5-aminolevulinic acid (5-ALA) has been utilized in primary brain lesions and metastases surgery to aid the identification of tumor limits and infiltration. Objectives: In this retrospective study, we demonstrate our experience with the first 41 cases Latin America of surgical resection of central nervous system (CNS) lesions with 5-ALA. Methods: In 41 consecutive patients, we recorded age, sex, histopathological diagnosis, intraoperative 5-ALA fluorescence tumor response, 5-ALA post-resection resection grade through magnetic resonance image (MRI) and other concomitantintra-operative techniques utilized (transoperative imaging, awake surgery, electrophysiological stimulation and monitoring). Results: Twenty seven high-grade gliomas and 4 non-glial lesions were 5-ALA fluorescence positive; 6 low-grade gliomas, 1 high-grade glioma and a hippocampal gliosis were 5-ALA fluorescence negative. In one case of a low-grade glioma, the patient developed a cardiac arrhythmia, probably not related to 5-ALA administration, but the surgery was suspended. Conclusions: 5-ALA fluorescence-guided surgery is a safe and easy technique to be used, increasing tumor total gross resection in glioma cases, proving to be an invaluable neurosurgical tool for intracranial tumor surgery. There was no serious side effect in this series. This dye should be utilized in all cases of high-grade gliomas.

Fluorescence-guided surgery (FGS) for high-grade gliomas using 5-aminolevulinic acid has become a new standard of care for neurosurgeons in several countries. In this video the authors present the case of a man with glioblastoma who underwent FGS in which similar images of the operative field were acquired alternating between the microscope and a new commercially available headlight, facilitating the comparison of visualization quality between the two devices. The authors also review some of the principles of fluorescence-guidance surgery that may explain the improved brightness and contrast that they observed when using the headlamp versus the microscope.

Abstract INTRODUCTION Fluorescence guided surgery with the use of 5-aminolevulinacid (5 -ALA) is nowadays the state of the art treatment of high grade gliomas. However, intraoperative visualization of 5-ALA under dark blue light remains challenging, especially when leaking blood covers parts of the surgical field, where tumor fluorescence becomes invisible. To overcome this problem and combine the brightness of visible light with the information delivered by fluorescence we developed multispectral fluorescence, a technique able to project both information in real time to the surgeon’s eyes, and embedded it on a surgical microscope. METHODS We examined 40 patients with brain tumors who underwent surgery, using the MFL operative technique. The tumors involved comprised of 20 glioblastomas, 7 astrocytomas WHO III, 5 meningiomas and 8 metastatic tumors. The MFL technique with the real-time overlay of 5-ALA fluorescence and white light was intraoperatively compared to the classic blue filter detecting 5-ALA fluorescence. RESULTS The tumor was in all cases clearly visible and highlighted from the surrounding tissues. The pseudocolor we chose to visualize the tumor was green, representing 5-ALA fluorescence, with the surrounding brain tissueremained in its origin white color. In the cases where blood was covering the surgical field, orientation was easy to maintain, due to the additional information delivered from the white light image. CONCLUSIONS The MFL technique embedded on a surgical microscope opens the way for a precise and clear visualization of tumor 5-ALA fluorescence in real time under white light. It can be easily implemented in the resection of all tumors accumulating 5-ALA. Drawbacks of classic 5-ALA fluorescence such as hidden fluorescence because of overlying blood could be overcome with the presence of additional white light and the clear visualization of the exposed brain.
