The role of indocyanine green video-angiography (ICG-VA) in the resection of vascular malformations

The role of indocyanine green video-angiography (ICG-VA) in the resection of vascular malformations has been largely described.

Intraarterial injection was feasible and useful to distinguish feeders from normal artery and to observe changes in flow dynamics. Intra-arterial injection of ICG had better phase contrast than intra-venous injection of ICG and better spatial resolution than digital subtraction angiography. Therefore, this technique can be helpful in arteriovenous malformation (AVM) surgery 1).
The utility of ICG-VA before dural opening (transdural ICG-VA) proved an efficient tool that allows optimising the exposure of the malformation, performing a safe dural opening and identifying dural vascular connections of the lesion 2).
