Abstract: Objective To investigate the effect of intraoperative ICG angiography on surgery for hemorrhagic cerebral arteriovenous malformation（AVM）. Methods Eight patients with hemorrhagic AVM were underwent craniotomy in our hospital from January 2010 to December 2021.Intraoperative ICG fluorescence angiography, preoperative CTA and postoperative DSA vascular imaging data were retrospective analyzed in 8 patients. The role of ICG fluorescence angiography in operation was evaluated by comparing intraoperative ICG fluorescence angiography with preoperative CTA and postoperative DSA angiography. Results Of 8 cases, the AVM was clearly developed by intraoperative ICG angiography. The images of feeding arteries and draining veins were consistent with preoperative CTA images. No vascular malformation was found on ICG fluorescence angiography after operation, which was consistent with DSA vascular imaging. Conclusion Intraoperative ICG angiography can show the scope of AVM, and clarify the feeders and drainers, which has guiding significance in the resection of hemorrhagic AVM.
