Abstract

Highlights: Fluorescein angiography seems to be a valuable alternative to indocyanin green in brain AVM surgery. Fluorescein and ICG might be used together. Bolus injections of fluorescein are well tolerated during brain surgery. Abstract: Brain arteriovenous malformations (AVM) are complex and highly challenging lesions, for which intra-operative indocyanin green fluorescence video angiography is widely used. Fluorescein video angiography (FVA) recently appeared as an alternative technique but the feasibility and usefulness of this technique is yet uncertain. This short series reports our preliminary experience of FVA in intracranial AVM surgery. We retrospectively studied the cases of seven patients who had FVA for an AVM surgery. The primary objective of this study was to assess the utility of FVA as judged by the surgeon. Secondary objectives were the evaluation of the tolerance of bolus injection of fluorescein in the context of cranial surgery, the comparison with ICG and the rate of complete removal. For each of the seven patients, FVA was performed after exposure of the AVM and before the resection; it was visualized directly through the eyepieces of the microscope and helped in the identification of arterial feeders and draining veins. In one case, post-resection FVA allowed the visualization of a residual shunt and the resection was completed. In two cases, ICG and FVA brought comparable information. The resection was complete in all cases, confirmed by post-operative imaging. There was no anaphylactic complication. This preliminary work suggests that FVA is a simple and well tolerated technique, comparable to ICG angiography. Prospective and larger studies are needed to confirm the clinical benefit of this tool.
