Objective To study the application of intraoperative indocyanine green videoangiography in the surgical treatment of intracranial aneurysms. Methods Ten patients harboring 10 intracra-nial aneurysms were retrospectively analyzed. All the patients routinely underwent indocyanine green videoangiography during the clipping of aneurysms. According to the result of fluorescent angiography, the clip was adjusted if necessary.Postoperatively, CTA was performed to confirm the complete aneurysm obliteration.Results During the operations,aneuryismal neck remnant was found in two cases, parent arteries stenosis was found in one case.According to the operative findings,the clips were replaced until satisfactory blood flow was restored.Complete clipping and parent bypass vessels were comfirmed by CTA exams. Conclusion Microscope-integrated ICG angiography is a useful tool in aneurysm surgery, which may provides real-time information during aneurysm surgery, and help the operator real-time inspection surgical operation effect. It will play an important role in improving the clinical outcomes of intracranial aneurysm. Thus it can effectively improve the prognosis of patients.
