Abstract: Objective Indocyanine green angiography (ICGA) is a promising technique for assessment of clipping for intracranial aneurysms. The present study was to examine Intra-operative ICGA may help for clipping of anterior cir-culation aneurysms. Methods Forty-five patients with anterior circulation aneurysms undergoing clipping were included. Pre-operative CTA was obtained to analyze the location, direction, size and shape of the aneurysms. Intra-operative ICGA was performed on Pentero microscope. Routine digital subtraction angiography (DSA) were obtained. Coincidence of ICGA and DSA was analyzed. Clinical outcome was evaluated using modified Rankin scale in 6 to 12 months after surgery. Re-sults Aneurysm’s parent artery and perforating branches were illustrated clearly on ICGA. Coincidence of ICGA and DSA for aneurysm remnant, patent artery narrowing and perforating branch occlusion were 97.8%, 93.3%and 91.1%, respec-tively. Conclusion Intra-operative ICGA is a quick, reliable and cost-effective assessment method of anterior circula-tion clipping, which may be useful during routine aneurysm surgery as an independent assessment or as an adjunct to intra-operative or postoperative DSA.
