Use of AR Fluorescence in Neurovascular Surgery

With GLOW800 Augmented Reality fluorescence, Dr. Renner recounts, it is possible to see the angiographic picture in the microscope directly during neurovascular surgery, with an optimal depth perception. There is no need to recall and try to reconcile the black and white blood flow video with the natural anatomical view.

As such, GLOW800 provides real-time information about blood circulation and perfusion during the arterial and venous phase. This information allows to select the safest way and strategy in the treatment of a lesion. It also helps verify the effective and definite elimination of the lesion.

Dr. Renner presented 5 clinical cases:

• 2 aneurysm clinical cases: GLOW800 supports aneurysm clipping procedures and helps confirm that the aneurysm is excluded from the circulation. For optimal depth perception, it is important to have the right working distance and magnification.

• A spinal dural arterio-venous fistula clinical case: the patient was operated using GLOW800. The fistula was clipped and GLOW800 allowed to confirm that the fistula was definitely excluded from the circulation.

• A complex cranial dural arterio-venous fistula patient case: the treatment was combined, with surgical exposure using GLOW800 and one of the fistula points eliminated through intraoperative coiling.  

• A low stroma hemangioblastoma patient case: the diagnosis was initially not clear and the surgeon removed a solid tumor to support the diagnosis. The procedure was performed with GLOW800 to visualize arterial inflow and identify the feeders.

GLOW800 provides real-time blood circulation and perfusion information within a controlled and tight workflow, without the need to turn away from the microscope.
