Abstract
Microscope-integrated indocyanine green video angiography (ICG-VA) is used to assess the completeness of clipping and cerebral vascular flow during aneurysm surgery.[1] It is a more practical and less time-consuming alternative to intraoperative digital subtraction angiography (DSA). ICG has been reported to cause a decrease in peripheral oxygen saturation (SpO2).[2] [3] [4]
