It is the most important to visualize cerebral vessels along with its surrounding structures during cerebrovascular surgery and it can be easier with real-time angiographic imaging. There are different kinds of indocyanine green dye based videoangiography are commonly used in cerebrovascular surgery. The objective. Comparative analyzing of ICG-AG, DIVA and Flow 800 color mapping in cerebrovascular surgery. Materials and methods. Real time surgery assessment of vascular and surrounding structures in 29 cerebral aneurysms clipping, one STA-MCA bypass and 2 carotid artery endarterectomy had been performed using ICG-VA, DIVA, flow 800 color mapping from August to October 2019. Result. In 23 cases in cerebral aneurysms clipping ICG-VA could not clearly visualize perforators compared to its’ better visualization by DIVA. In 3 cases, occlusion of perforators were assessed by DIVA after clip application which was solved by reapplication of surgical clips. In one STA-MCA bypass surgery, patency and sequences of blood inflow to cortical branches of MCA (M4) from recently anastomosed STA branches were assessed with ICG-VA, DIVA and Flow 800 color mapping. Visualization of the lack of blood flow and fluttering atherosclerotic plaques in carotid endarterectomy was observed by ICG-VA, DIVA, flow 800 mapping. Conclusion. In real time cerebrovascular surgery, ICG-VA, DIVA, and Flow 800 color mapping can be effective tool to better visualization of vascular and surrounding structures. Benefits of flow 800 color mapping outweighs the advantages of both ICG-VA and DIVA. However, DIVA is also better than ICG-VA to visualize
