Abstract:
Objective Indocyanine green (ICG) video angiography is widely used in aneurysm surgery.This study is to evaluate and analyze the effect of intraoperatively aneurysms clipping by quantitative analysis of ICG video angiography.Methods Twenty patients with cerebral aneurysms (six with anterior communicating artery aneurysms,five with communicating artery aneurysms and nine with middle cerebral artery aneurysms),admitted to our hospital from September 2012 to September 2013,were chosen in our study; they all underwent aneurysms clipping involving ICG.Same areas of interest (AOIs,aneurysm area,parent artery area and branch artery area) of images intercepted from angiogram videos before and after clipping of aneurysms were analyzed by Image-pro plus.Results Dramatic differences in time to peak of blood flow of aneurysm areas were observed before and after clipping of aneurysms ([10.975±1.208] s vs.[47.950±2.350] s,t=57.299,P=0.000).There were no dramatic differences in times to peak of blood flow of parent and branch vessels before aneurysms clipping and after aneurysms clipping ([10.600±1.619] svs.[10.350±1.452] s,t=0.641,P=0.529;[10.400±1.153] s vs.[10.425±1.311] s,t=-0.079,P=0.938).Conclusion Quantitative analysis is a good method to evaluate the effect of aneurysm clipping surgery according to the blood flow,which might improve the success rate.
