研究概览
简要总结
The purpose of this study is to see if there is benefit to using an IV contrast called AK-Fluor® and a microscope filter called YELLOW560 when surgically removing a vestibular schwannoma, Meningioma, Head and Neck Paraganglioma, or Head and Neck Schwannoma.

研究组 & 干预措施
Fluorescein sodium (FS) and YELLOW 560 nm microscope filter (YE560) during surgery
Subjects undergoing clinically planned vestibular schwannoma, Meningioma, Head and Neck Paraganglioma, or Head and Neck Schwannoma, removal surgery will have contrast agent fluorescein sodium administered intravenously after tumor exposure, and a special filter called YELLOW560 will be used on the operating microscope to see the fluorescent coloring of the contrast.
干预措施: Fluorescein Sodium (Drug)

结局指标
主要结局
Surgeon Predicted Use of Fluorescein Sodium in Future Cases
时间窗: Approximately 3 months postoperatively
Physician response to surgeon survey question, "Based on the use and performance of FS in this case alone, how likely are you to use FS in future cases (excluding the research trial) involving this tumor?" using a Likert-style rating from 0-4 where 0=Unsure; 1= Plan to not use in any cases; 2= Plan to use in select cases; 3=Plan to use in the majority of cases; 4=Plan to use in all cases.
Correlation of Fluorescein Sodium With Surgeons' Visual Assessment
时间窗: Intraoperatively, approximately 1 day
Fluorescence correlate with surgeons' visual assessment of the tumor and nerve tissue under normal microscopy without the Yellow 560 filter using a Likert-style rating from 1-4 where 1=No correlation; 2=Some correlation; 3=Good correlation; 4=Excellent correlation.
Correlation of Fluorescein Sodium With Electrostimulation
时间窗: Intraoperatively, approximately 1 day
Surgeons' assessment of fluorescence correlate with electrostimulation (e.g. tissues with high fluorescence do not stimulate, whereas nerve tissues with low fluorescence do stimulate)" using a Likert-style rating from 1-4 where 1=No correlation; 2=Some correlation; 3=Good correlation; 4=Excellent correlation.
次要结局
- Time to Differential Visualization(Intraoperatively, approximately 1 day)
- Average Dose of Sodium Fluorescein Administration(Intraoperatively, approximately 1 day)
- Total Resection Rate(Intraoperatively, approximately 1 day)
