Hands we are having continuing {problems
Hands we are obtaining continuing challenges utilizing this approach and are just not observing the selectivity that we would desire. In our knowledge with metastases (Fig. 1) and malignant gliomas (Supplementary Video), significant fluorescein fluorescence is identified after resection at the margins in obviously standard and perifocal edematous brain tissue in spite of all efforts to follow the guidance of Dr. Acerbi and coworkers using low doses (four mg/kg) given with induction of anesthesia and performing surgery using the Zeiss Yellow 560 filter program. This confounds applicability.AWLAYellowBWLBYellowCWLCYellowDWLDYellowElectronic supplementary material The on the web version of this short article (doi:10.1007/s00701-015-2576-4) contains supplementary material, that is offered to authorized customers. Walter Stummer [email protected] of Neurosurgery, University of M ster, Albert-Schweitzer-Campus 1, Geb de A1, 48149 M ster, GermanyFig. 1 Metastasis of adenocarcinoma with perifocal edema, operated on using fluorescein (four mg/kg i.v., injected right away immediately after induction of anesthesia; Zeiss Yellow 560, filter) as previously described [1, 2]. a Prior to corticotomy; note decreased cortical fluorescence covering the tumor, indicating lowered perfusion by fluorescein. Considerably more fluorescence is identified cortically away from the tumor, where perfusion is greater and edema reaches the cortical surface (image captured 72 min following injection). b Following opening the cortex; little fluorescence is located in the tumor. Within the meantime, more fluorescein is accumulating in perifocal cortical tissue (image obtained 96 min just after injection and frozen section confirming metastasis). c Following resection of tumor. The entire cavity fluoresces. There is unspecific fluorescence in the adjacent (edematous) cortex (image obtained 144 min soon after injection). d Higher magnification of image c (WL white light illumination; Yellow560 using the Zeiss Yellow 560 filter)Acta Neurochir (2015) 157:2199200 distribution, and purchase CFI-402257 reproduction in any medium, supplied you give suitable credit to the original author(s) as well as the source, offer a link towards the Creative Commons license, and indicate if modifications were created.We locate this worrisome. Our differing vantage points have definitely now generated a very lively discussion. Dr. Acerbi et al. feel (wrongly) accused, with accusations absolutely not getting been my intention. I hugely respect their efforts to improve the surgical management of brain tumor individuals. Nevertheless, I do critically reiterate that I believe the use of fluorescein outdoors of studies to become premature and requiring further investigation within a complicated field in which histology, timing, dose, illumination, tissue perfusion, and edema play a part, with a marker of blood rain barrier integrity that offers a tissue signal which is not basically binary. Other folks are critical as well [4, 5]. Dr. Acerbi et al. are thankfully involved in such research and other folks and I are awaiting their outcomes.
